List of Tom and Jerry characters

This article contains the list of characters featured in the Tom and Jerry animated series, given in the order of the era, they first appeared in.

Tom Cat and Jerry Mouse
Tom (originally called "Jasper") is a bluish grey and white domestic shorthair cat. He is usually, but not always, portrayed as living a comfortable and pampered life, while Jerry (originally called "Jinx"), a brown house mouse, is always living in close proximity to Tom. Despite being very energetic, determined, and much larger, Tom is no match for Jerry's wits. Jerry also possesses surprising strength for his size, sometimes even stronger than Tom's, being able to lift items such as anvils with relative ease, able to withstand big impacts. Although cats usually chase mice to eat them, it is quite rare for Tom to actually try to eat Jerry, but to either compete with Jerry as usual to taunt him (even as revenge), to obtain a reward from a human (including his owner(s) or master(s)) for catching him, or for generally doing his job as a house cat well. By the final "fade-out" of each cartoon, Jerry usually gets the best of Tom.

However, there are rare occasions where Tom triumphs over Jerry, mostly when the latter pushes Tom a little too far, such as in The Million Dollar Cat, where Jerry learns that Tom will lose his newly acquired wealth if he harms any animal, "including mice." He then torments Tom a little too much until he retaliates. In Timid Tabby, Tom's look-alike cousin pushes Jerry over the edge. Occasionally and ironically, sometimes they both lose, like when Jerry's final trap or attack on Tom backfires or he overlooks something, like in Filet Meow, where Jerry orders a shark from the pet store to scare Tom away from eating a goldfish, but finds himself entirely intimidated as well. They occasionally end up being friends, although within this set of stories, the truce is often ruined by some last minute event. One story that has a friendly ending is Snowbody Loves Me.

Both characters display sadistic tendencies, usually taking pleasure in tormenting each other, although it is often in response to a triggering event. However, when one character appears to be in mortal danger from an unplanned situation, or due to actions by a third party, the other will develop a conscience and save him. Occasionally, the duo can bond over a mutual sentiment towards an unpleasant experience and their attacking each other is more of a game than serious. Multiple shorts show the two getting along with minimal difficulty, and they are more than capable of teamwork when the situation calls for it, usually against a third party who manages to torture and humiliate them both. These partnerships are usually forgotten about when an unexpected event happens, or when one character feels that the other is no longer necessary. This is the case in Posse Cat, when they agree that Jerry will allow himself to be caught if Tom agrees to share his reward dinner, but Tom then reneges. Other times, however, Tom does keep his promise to Jerry and the partnerships are not so quickly dissolved after the problem is solved.

Hanna-Barbera era (1940–1958, 2000–2005)
The following characters were introduced in the theatrical shorts that were directed by William Hanna and Joseph Barbera.

Spike and Tyke
Spike, occasionally referred to as Butch or Killer, is a stern though occasionally dim-witted grey bulldog who is particularly disapproving of cats, but is gentle towards mice (though in his debut appearance, Dog Trouble (1942), Spike goes after both Tom and Jerry), and later, his son Tyke. In the shorts, Jerry would often try to get Tom in trouble with Spike so that the bulldog would beat him. Spike has a few weaknesses that Tom tries to capitalize upon: his possessiveness about his bone and his ticklishness. His first speaking role was in The Bodyguard (1944), where he was voiced by Billy Bletcher up until 1949, from which point he was voiced by Daws Butler. Spike is very protective towards his son and gets very angry at Tom if Tyke is bothered or harmed. After Daws Butler, Maurice LaMarche, Frank Welker, John DiMaggio, Michael Donovan, Phil LaMarr, Rick Zieff, and currently Bobby Cannavale would all perform Spike's voice. Unlike his father Spike, Tyke does not speak in Tom and Jerry or the 2014 TV series (aside from laughing in one short); he does speak in Tom and Jerry Kids, voiced by Frank Welker and speaking roles by Patric Zimmerman.

Nibbles
Nibbles (also known as Tuffy) is a little, blue/gray, diaper-wearing orphan mouse who is close to Jerry and appears frequently with him, especially in the comics. His cartoon debut came in the short The Milky Waif (1946). Nibbles was later featured in the Academy Award-winning short The Little Orphan (1949).

He is sometimes seen as Jerry's nephew, but occasionally referred to as an orphan. Although these details are very inconclusive. Nibbles is often shown eating excessively as he is always hungry. In his first animated appearance, Tuffy was left on Jerry's doorstep, abandoned by his parents. Tom enjoys chasing Nibbles/Tuffy as much as he does Jerry.

Though the character was created under the name Tuffy for the comics in 1942, his early animated appearances (from 1945) gave him the name Nibbles. During the 1950s and subsequently, the mouse was called Tuffy on-screen as well. In Tom and Jerry: The Magic Ring (2002), the name Nibbles was used again; and he was depicted as a pet-store mouse whom Jerry doesn't know.

In the Mouseketeer shorts, Nibbles speaks in French and English. He also is not Jerry's nephew; rather, he is the son of François Mouse—who does not make an appearance, but his name was given in two letters in the short Touché, Pussy Cat! (1954).

Like his guardian Jerry, Nibbles is often mistaken for a girl due to his extraordinarily high pitched voice. He was voiced by Francoise Brun-Cottan in the Mouseketeer shorts, Lou Scheimer and Frank Welker in The Tom and Jerry Comedy Show, Charlie Adler in Tom & Jerry Kids, Tara Strong in Tom and Jerry: The Magic Ring, Kath Soucie from 2010 onwards, and Alan Marriott in the video games Fists of Furry (2000) and War of the Whiskers (2002).

Butch
Butch (voiced by Frank Graham in Springtime for Thomas and Trap Happy (both 1946), Raul Martinez in Springtime for Thomas (singing voice), Jerry Mann in Casanova Cat (1951), Stan Freberg in Baby Butch (1954) and Daws Butler in Smarty Cat (1955) and Scat Cats (1957); by Nicky Jam in the 2021 film ) is a black alley cat who made his first appearance in the Tom and Jerry series in the short Baby Puss (1943), alongside Topsy and the already-established Meathead. He was voiced in the short by Jack Mather. His character, however (along with the character of Toodles Galore), first appeared in the MGM short (and Butch's only solo cartoon) The Alley Cat (1941), directed by Hugh Harman, and was voiced by Harry E. Lang. Butch is the leader of the alley cat bullies who are usually friends with Tom and help him catch Jerry. In his first appearance, Baby Puss (1943), Butch was an antagonist, tormenting Tom after Tom's young girl owner treated him like a baby—to the point of dressing Tom up in a diaper, a bonnet, and pink paw mittens. Thus costumed, Tom couldn't help, but be a figure of fun—both for Butch and his gang, and for Jerry. Butch also battles with Tom over Toodles Galore and her affections, creating a love triangle between him and Tom in a couple of shorts including the shorts, Springtime for Thomas (1946) and Casanova Cat (1951). In some cartoons, such as A Mouse in the House (1947), Butch battles with Tom to catch Jerry. Butch is usually portrayed as a homeless alley/street cat although in the short, Blue Cat Blues (1956), Butch is apparently a millionaire who wins the attention of Tom's love interest due to his immense wealth much to Tom's dismay. Butch also appears in a cartoon in the short-lived Spike and Tyke cartoon series, Scat Cats (1957), as a house cat owned by George and Joan, who in later installments of the original series own Tom.

In much later cartoons, he is voiced by Maurice LaMarche in Tom and Jerry: The Magic Ring (2002), Tony Cervone in The Karate Guard (2005), Colin Murdock in Tom and Jerry Tales (2006–08), Alan Marriott in Tom and Jerry in Fists of Furry (video game, 2000), Marc Silk in Tom and Jerry in War of the Whiskers (video game, 2002), Joey D'Auria in The Tom and Jerry Show (2014–2021) then onwards, and Nicky Jam in Tom & Jerry (2021).

Toodles Galore
Toodles Galore is an attractive white female cat, who usually wears a large blue bow around her neck, and is supposedly Tom's love interest, although Tom is a reputed playboy, and had other love interests before and after Toodles. Toodles is the only love interest who appeared more than twice. During the classic era, Tom had to compete twice against Butch and even once against Spike for Toodles's affection, and he lost them all. In Casanova Cat (1951), Toodles even fell in love once with Jerry.

Toodles is one of the more anthropomorphic animals in the early series, but her depiction varies by period. She never speaks and she rarely moves around. She has a feline main body, not a human one; however, details like whiskers come and go. She also has cat ears and nose. However, she has many human attributes. She sits in very human poses and walks on two feet (as does Tom in all but the very early shorts, where he chases Jerry on all fours). She has human-shaped hands with painted nails, and rather human eyes and lips made up as a human woman of the era might. In most appearances, like the other cats, she wears nothing but her fur, but she wears a bathing-suit in one early episode with a human feminine figure.

In the later series, The Tom and Jerry Show (2014–2021), for example, her appearance and attitude is shown even more anthropomorphically as she wears human clothes and accessories. She is also shown in a cream color instead of white. In the show, she is heard speaking for the first time, as voiced by Alicyn Packard. She also appears in Tom and Jerry in New York, voiced by Rachael MacFarlane.

Mammy Two Shoes
Mammy Two Shoes (voiced by Lillian Randolph) is an African-American woman. Whether or not she is a maid taking care of the home in which Tom and Jerry reside or the homeowner is never made clear. Her face is never seen (with the exception of Saturday Evening Puss (1950), in which her face is very briefly seen as she runs towards the viewer), and she usually wallops the cat (whom she usually addresses as "Thomas") with a broom whenever he misbehaves. She sometimes tries to get rid of Jerry's presence in the house. Mammy would appear in 19 cartoons, starting with Puss Gets the Boot (1940) and ending with Push-Button Kitty (1952). The character eventually became controversial due to being based on the Mammy archetype, and was retired from the series in 1953. Gene Deitch opted not to use Mammy's character in his shorts, as he felt a "stereotypical black housekeep" character "didn't work in a modern context."

Quacker
Another recurring character in the series was Little Quacker the duck, who was later adapted into the Hanna-Barbera character Yakky Doodle. He appears in Little Quacker (1950), Just Ducky (1953), Downhearted Duckling (1954), Southbound Duckling (1955), That's My Mommy (also 1955), Happy Go Ducky (1958), and The Vanishing Duck (1958). Quacker talks a lot compared to Tom and Jerry. His voice is a 'duck voice' similar to Disney's Donald Duck. In many shorts, he is the only character who speaks. He is very trusting, even trusting Tom in many situations in which Tom wishes to eat him. He is a friend of Jerry, but unlike Jerry harbors no hard feelings towards Tom. He appeared in The Tom and Jerry Show episode "The Lost Duckling" (1975). He also got his own series of shorts on The Yogi Bear Show (renamed Yakky Doodle) after guesting in several Hanna-Barbera TV shows. Quacker was then used as a template for the 'Hard Luck Duck' character starring in the titular character's short from the What a Cartoon! series. His What a Cartoon! counterpart Hard Luck Duck was voiced by Russi Taylor.

Quacker was voiced by Red Coffey in the classic shorts, Don Messick in The Tom and Jerry Show (1975) and Alan Marriott in Tom and Jerry in Fists of Furry and Tom and Jerry in War of the Whiskers. He was named "Duckling" in those games.

In Tom and Jerry Show, Quacker's "duck voice" is provided by Sam Kwasman.

In three cartoons, Quacker becomes separated from his mother at birth, only to reunite with her later in two of them (Little Quacker and Just Ducky). In That's My Mommy however, he is adopted by Tom. In Little Quacker, Quacker's father, Henry makes an appearance. Because his birth is shown differently in different cartoons, he may have siblings as seen in Just Ducky and Happy Go Ducky.

Quacker gets a girlfriend named Fifi in Downhearted Duckling.

Cuckoo
Cuckoo is a canary that first appeared in Kitty Foiled (1948). He also appeared in The Flying Cat (1952), Life with Tom (1953), Hic-cup Pup (1954), Two Little Indians (where he is red in color), and Matinee Mouse (which shows clips from the previous episodes). He is Jerry's best friend. Despite being a little bird, he can actually carry heavy objects like a bowling ball in Kitty Foiled and a 2000 lb. weight in The Flying Cat.

Lightning
Lightning is a ginger orange cat who first appeared in the short Old Rockin' Chair Tom (1948) as Tom's rival. Lightning is named as such because in his first short, he practically moved at the speed of lightning. In later cartoons, Lightning often appeared as one of Tom's alley cat buddies/rivals. Lightning has the same character design as Butch, but with an orange color (although his coloring occasionally varies from film-to-film). In Mucho Mouse, he speaks Spanish and is a house cat. He also appears in the Gene Deitch short Switchin' Kitten. In the Chuck Jones short Catty-Cornered (his final appearance), Lightning is portrayed with more of an orange-yellow color than before, with the additional changes of a black tail and ears. Lightning also appears in the live action film where he is voiced by Joey Wells.

Topsy
Topsy is a grey/brown Scottish Fold kitten. He is one of Tom's alley cat friends/foes, although in Professor Tom he befriends Jerry. He first appeared in Baby Puss; his final appearance in the original theatrical shorts was in Scat Cats. He also appears in Tom and Jerry Tales with a more yellowish color (similar to Life with Tom). In Professor Tom, Topsy is explicitly a house cat; more often (as in Saturday Evening Puss and elsewhere), he is depicted as an alley cat or a cat of unknown origin. In the live action film, Topsy is voiced by Harry Ratchford.

Meathead
Meathead is a brown, mangy alley cat who wears a red toupee (which is occasionally seen the same color as the rest of his fur). He is generally portrayed as dull-witted and first appeared in the short, Sufferin' Cats! (1943), as Tom's rival. He also appears in Baby Puss and additional shorts as one of Tom's alley cat buddies/foes. He is known as Frankie in Heavenly Puss. In Scat Cats, his final appearance in the original theatrical shorts, he is portrayed with an all-gray color.

Meathead appears in several episodes of Tom and Jerry Tales with an orange color similar to that of Lightning and also has a red nose and, in two episodes, a bushy tail.

Meathead re-appeared in The Tom and Jerry Show episode Cruisin' for a Bruisin' as a lead antagonist, while a drag version of the character named Meathelda appeared in the episode Hop to It! Meathead also makes multiple appearances in later seasons, usually alongside Butch and other alley cats.

Meathead also appears in the live action film where he is voiced by Na'im Lynn.

George and Joan
George and Joan (voiced by Daws Butler and June Foray respectively) are an average middle-class white couple, who debuted in the short Pet Peeve (1954), replacing Mammy Two Shoes. They are the owners of Tom, Jerry, and Spike, but Tom likes to keep Joan company and Spike likes to keep George company. Joan is often seen either cooking or sitting on her armchair knitting or sewing a dress with Tom keeping her company. George, on the other hand, hates the monthly bills and complains that they're too expensive. But when he's not complaining about the bills, he is sitting in his armchair or on the sofa reading the newspaper wearing his smart purple or grey suit and Spike is keeping him company. Both George and Joan are very kind and polite towards each other and Tom and Spike. In Pet Peeve, George and Joan decided to keep Jerry as a pet because he is easy to look after and doesn't eat too much (George and Joan do not know Jerry's secret: he has stored a large amount of food in his mouse hole, leftover from Tom's and Spike's carelessness with their food.) and tell Tom and Spike to leave. However, in later shorts with George and Joan, Tom and Spike still happily live with them and Jerry is not known by the couple and he isn't a pet.

George and Joan also appeared in three other Tom & Jerry shorts: Tom's Photo Finish, Busy Buddies, and The Vanishing Duck (Quacker's last short), and one Spike and Tyke short, Scat Cats.

In some shorts, Joan appears without George, such as Mouse for Sale, The Flying Sorceress, Mucho Mouse, and Tot Watchers. It could be presumed that George would be working at his office during the settings of these cartoons.

Jeannie and the Baby
Jeannie, the babysitter of George and Joan's baby, is an average teenager who spends much of her time talking on the phone. She is often called on to look after the baby if they're going out. Jeannie proceeds to leap straight onto the phone just as George and Joan shut the front door, which implies that she is very negligent about her job. Despite this, Jeannie is very kind, friendly, cheerful, and rarely loses a smile—except to scold Tom for "bothering the baby", which she thinks that he and Jerry are doing on purpose to annoy her. Jeannie and the baby were seen in only two cartoons: Busy Buddies (1956) and Tot Watchers (1958). Jeannie is voiced by Janet Waldo in the original shorts. The baby also appears in Tom & Jerry Kids where the babysitter is slightly younger and a redhead instead of a blonde. Due to modern sensibilities, this negligent-based climax would no longer be replicated in the newer entrees since child neglect became a very serious matter.

A handful of teenage babysitters do the similar climax as Jeannie's on The Flintstones.

The Ants
The Ants are an army of red ants who steal food as they see them. They appeared in four cartoons Cat Napping, Pup on a Picnic, Barbecue Brawl, and Carmen Get It!. They also appeared in Tom & Jerry Kids. They're unusually heavy for their size, and their combined weight often causes many items, such as Tom's hammock, to break. It is unclear how or why the ants are so heavy, as they are even capable of making tables and diving boards shake as they march onto them.

Guardian devils
Each guardian devil for Tom and Jerry appeared in three cartoons Sufferin' Cats! (1943), Springtime for Thomas (1946), and Smitten Kitten (1952). In the first of these cartoons, one served as evil conscience for Tom and in the other one for Jerry.

Goldfish
A tiny goldfish who lives in the same house as Tom and Jerry. She appeared in first debuts in The Little Goldfish (1939) by Rudolf Ising. Later, major roles in Jerry and the Goldfish (1951) and Filet Meow (1966) (although the goldfish in the latter could be a different one), where Tom's attempts to eat her lead to Jerry winning her affections. She mostly appeared in cameo roles in other cartoons Puss Gets the Boot (1940), Puss n' Toots (1942), Baby Puss (1943), The Million Dollar Cat (1944), Casanova Cat (1951), The Missing Mouse (1953), Haunted Mouse (1965), and The Brothers Carry-Mouse-Off (1965).

Muscles
Muscles is Jerry's cousin and a mouse with incredible strength. In Jerry's Cousin (1951), Muscles appears to hate cats, including Tom. In Haunted Mouse, another mouse named Merlin, who is also a cousin of Jerry's, appears as a wizard with magical abilities. Muscles' other appearance was in Tom and Jerry: The Magic Ring, however, his name was changed to Freddie and he was hostile towards Jerry (although it could be a different mouse who is identical to Muscles). He was voiced by Paul Frees in Jerry's Cousin and by Billy West in Tom and Jerry: The Magic Ring. He also appeared in The Tom and Jerry Show.

George the Cat
George is the cat counterpart of Muscles, but with a personality that is in stark contrast to him. Like Muscles, George is identical to Tom (although he is shorter) and is his cousin. Unlike Muscles, however, George is a coward and is scared of mice. He first appeared at the beginning of Jerry's Cousin where he gets thrashed by Muscles (possibly the reason for his fear of mice). His bigger role was in Timid Tabby (1957) where he finally overcomes his fear. He also appeared in Tom & Jerry Kids, the early 1990s television series, where his fear seems to have re-instated even though he pretended it had not (his name was changed to Tim in that short). He is voiced by Bill Thompson.

Fluff, Muff, and Puff
Fluff, Muff, and Puff are a trio of brown, black, and orange kittens that first featured in Heavenly Puss (1949) in a cameo appearance (during Tom's dream) as charming kittens who drowned. They also appeared as cute but mischievous kittens in Triplet Trouble (1952). They were also on The Tom and Jerry Show.

Chérie
Chérie is a brown/grey female mouse who serves as Jerry's love interest. She first appeared at the end of Springtime for Thomas (1946), and then later in Smitten Kitten (1952), Touché, Pussy Cat! (1954, the only cartoon where she has an identical twin), Tom and Chérie (1955, the first cartoon where she is named, but only seen in silhouette form) and The Mouse from H.U.N.G.E.R. (1967, as a ticking time bomb set by Tom).

Toots
Toots is the name given to three different characters that have appeared infrequently. The first of these is a fluffy beige cat who appears in Puss n' Toots (1942) and in The Mouse Comes to Dinner (1945), the latter being her only speaking role. She also has a cameo in The Bodyguard (1944) and Smitten Kitten (1952). This version of Toots also appeared in some 1940s Tom and Jerry comics, and in the 2021 theatrical movie. Toots is also a different cat by the same name who appears in The Zoot Cat (1944) and in the Tom and Jerry Tales episode "Kitty Cat Blues". She has occasionally and erroneously been referred to as "Sheikie", but this is actually Tom's nickname, as seen on a gift card in the cartoon. Finally, Toots is the name of a mouse who serves as Jerry's love interest in Blue Cat Blues (1956). Toots also appeared as an antagonist in Love Me, Love My Mouse (1966).

King of France
In some of the mouseketeer series of cartoons, Tom serves the king of France. This is an obvious reference to Louis XVI of France, who is shown as an extremely short-tempered and cruel monarch. In The Two Mouseketeers (1952), the king executes Tom while in Royal Cat Nap (1958), he orders for Tom's execution.

Mechano cat and Robot-Mouse
Mechano cat first appeared in Push Button Kitty (1952) as Tom's rival. Later, Mechano and Robot-Mouse are seen as a cat-like-robot and mouse-like-robot who serve Tom and Jerry (except at the end of Advance and Be Mechanized (1967), when they get revenge and switch roles with Tom and Jerry, as they control their minds and make them do the work) in the three Chuck Jones outer space cartoons O-Solar Meow, Guided Mouse-ille, and Advance and Be Mechanized (both 1967). Mechano's efforts to catch or trap Jerry or Robot-Mouse always backfire for Tom, except in Advance and Be Mechanized, when he succeeds to catch Robot-Mouse in the beginning. In Guided Mouse-ille, he can stand upright and have hands to use a gun to try and blast Jerry in his mobile tank. This backfired and left Mechano with a black face, while crying in frustration. He sneaks back and promptly shoots Tom, who attempts to shoot Mechano back for his insubordination. However, the shot came out on the wrong end and Tom faints leaving Mechano laughing himself silly. He also appeared in the Tom and Jerry Tales episode "Tin Cat of Tomorrow" (2006) where he is named Verminator 7000. Mechano (called "Robot Cat") also appeared as a fighter in the video game, War of the Whiskers (2002), and was voiced by Marc Silk.

The St. Bernard
The St. Bernard is a dog who first appeared in Puttin' on the Dog (1944) and then again in The A-Tom-Inable Snowman (1966). Unlike the other dogs in the franchise, he is not hostile to cats and on one occasion becomes Tom's medical aid. He also appeared in War Dogs and Little Cesario.

Eagle
Eagle is an eagle that tries to steal Jerry for food from Tom. He first appeared in Flirty Birdy, then in The Tom and Jerry Show episode "The Egg and Tom and Jerry" (1975, where he is female instead of male) and then again in Tom and Jerry Tales episode "Bend it like Thomas" (2007). Eagle also appeared as a playable character in the video game War of the Whiskers (2006), voiced by Marc Silk.

Lion
Lion is a lion that debuted in Slap Happy Lion (1947) by Tex Avery. He has switched from a tame one in Jerry and the Lion (1950), to a nervous one in The Tom and Jerry Show episode "The Hypochondriac Lion" (1975) to a monster in the Tom and Jerry Tales episode "You're Lion" (2007). He is also a playable character in Tom and Jerry in War of the Whiskers where he is voiced by Alan Marriott.

Baby Woodpecker
A baby woodpecker that first appeared in Hatch Up Your Troubles (1949) and its remake The Egg and Jerry (1956) where he could peck into virtually anything including Tom's stomach, Tom's golf club in Tee for Two (1945) or a water pipe as in Landing Stripling (1962). Baby Woodpecker and his Mama would re-appear by making cameo appearances in The Tom and Jerry Show which ran from 2014.

Uncle Pecos
Uncle Pecos is Jerry's cowboyish uncle who appears in Pecos Pest (1955). He was voiced by Shug Fisher. He is known to always play with a guitar and wears a black cowboy hat that covers his eyes. He plucks each of Tom's whiskers off to replace broken strings on the guitar. Being from Texas, he is shown to be super strong and is also shown to have a stammer, especially while singing.

Uncle Pecos returned in the Tom and Jerry Tales episode "Cry Uncle" (2006), voiced by Scott McNeil. In the episode, he arrives at Tom and Jerry's house and annoys Tom and Jerry with his music. He later leaves with Auntie Spinner in the end of the episode. Uncle Pecos made his second return in The Tom and Jerry Show, voiced by Stephen Stanton. He appears in the episodes, "I Quit", "Uncle Pecos Rides Again" and "Cat-A-Tonic Mouse" (all 2018).

Radio
A radio with a male human voice that broadcasts music, cookery shows and warnings on escaped animals, bomb threats etc. In Jerry's Diary (1949), the radio is shown to be anthropomorphic (with the announcer's name as 'Uncle Dudley') but this is not the case with other cartoons. The radio's announcements often cause troubles for Tom, as in Jerry and the Lion (1950), Little Runaway, (1952) The Missing Mouse (1953), and Down Beat Bear (1956), fear in Fraidy Cat (1942), embarrassment in Jerry's Diary (1949) and Life with Tom (1953) or as in Jerry and the Goldfish (1951) may be the cause of evil intentions.

Radio has been voiced by Martha Wentworth in Fraidy Cat, by Paul Frees in The Missing Mouse and Jerry and the Lion, Joseph Forte in Jerry's Diary and Daws Butler in Jerry and the Goldfish, while others are not known.

Jackass
Unlike the other Tom and Jerry characters, this one is not a character per se, but rather a substitution for a character, such as Spike the Bulldog, for a brief visual gag. Usually, a character turns into a jackass when it is fooled such as Spike in Solid Serenade (1946), The Framed Cat (1950), and Pet Peeve (1954) or Tom in Polka-Dot Puss (1949). In Pup on a Picnic (1955), 'Jackass' is replaced with 'Sucker'.

Gene Deitch era (1961–1962)
The following characters were introduced in the theatrical shorts that were directed by Gene Deitch in the early 1960s.

The Grumpy Owner
An overweight, short-tempered, average height, middle-aged, and bald white man became Tom's owner only in three of the thirteen cartoons: Down and Outing (1961), High Steaks (1962), and Sorry Safari (also 1962). Unlike any of the other owners and Spike the Bulldog, he has severe anger issues and is repeatedly violent towards Tom for his actions. He is voiced by Allen Swift.

The Grumpy Owner bears a strong resemblance to another character created by Deitch: Clint Clobber, the property manager of a rundown apartment building who had been created for Terrytoons in the mid to late 1950s. There is some debate as to whether the Owner and Clobber were the same character; however, Deitch claimed they were in fact different characters. While Clobber is portrayed to have a short temper, he is portrayed more as a man down on his luck, and never shown to be physically violent towards others nor depicted to be excessively cruel to animals.

Mad Scientist
He is a mad scientist reminiscent of Frankenstein. He first appeared in Switchin' Kitten (1961) and subsequently was the subject of a number of television episodes (for e.g. 'Trojan Dog' in The Tom and Jerry Comedy Show, 1980–82) and movies thereafter. In his first appearance, the mad scientist is the owner of Jerry (who is also his assistant) and has numerous cats trapped in a prison. When Jerry picks an orange cat named Lightning, the other cats flee in terror as the scientist pulls him out for his latest experiment. He switches the mind of the orange cat with that of a bulldog and presents him as his present to Jerry.

Thin Lady
An unnamed thin white lady was Tom's owner in Buddies Thicker Than Water (1962). Chuck Jones would also use her in The Unshrinkable Jerry Mouse (1964) and in the revised version of Saturday Evening Puss. She also appeared in the movie Tom and Jerry: The Fast and the Furry (2005). Like many other early owners, her face was never shown.

Chuck Jones era (1963–1967)
The following characters were introduced in the theatrical shorts that were produced by Chuck Jones in the mid to late-1960s.

Tiny Bulldog
This nameless mouse-sized bulldog, designed similarly to Spike the Bulldog, is Jerry's pet dog companion in only two shorts: The Cat's Me-Ouch (1965) and Purr-Chance to Dream (1967). His role is similar to Spike in cartoons such as The Bodyguard (1944), Fit To Be Tied (1952), and Much Ado About Mousing (1964), which is to defend Jerry against Tom. He is presumably the oldest son of Spike before Tyke, and this could be identified by his looks and personality that is similar to his father Spike. Unlike Spike and Tyke, he has a big bite (similar to those of Looney Tunes' Tasmanian Devil).

Porpoise
A shark who tries to eat Tom and Jerry. He appears in Puss 'n' Boats and Filet Meow (both 1966) and Surf-Bored Cat and Cannery Rodent (both 1967). The creature's color and species varies, in Cannery Rodent and Surf-Bored Cat it is a blue shark, while in Filet Meow and Puss 'n' Boats it is a great white shark.

Porpoise also appeared in The Tom and Jerry Comedy Show episode "A Connecticut mouse in King Arthur's court" (1980).

The Tom and Jerry Show (1975)
The following characters were introduced in The Tom and Jerry Show television series which ran for the first half of the 1975 season.
