List of Ultraman Tiga characters

Ultraman Tiga (ウルトラマンティガ) is a Japanese tokusatsu TV show and is the 11th show in the Ultra Series. Produced by Tsuburaya Productions, Ultraman Tiga was aired at 6:00pm and aired between September 7, 1996, to August 30, 1997. Following Tiga ' s conclusion, the series was succeeded by Ultraman Dyna (ウルトラマンダイナ) from September 5 1997 until August 28 1998.

Shin Asuka
Shin Asuka (アスカ・シン) is the main protagonist of Ultraman Dyna and is Ultraman Dyna's human host. Aged 22 years old in the series, he is light-hearted overall, and is one of the rare Ultra human hosts who also serves as the comic relief of the main cast. Asuka often whines and pouts immaturely, and sometimes pretends to be killed in combat just to see his teammates freak out. Despite his immature outlook, he can also be headstrong and overly courageous, fending off aliens far stronger than normal humans with only his hand-to-hand combat skills. His well-known motto is "Never give up", stemming from his character development as his series progresses. Using the Lieflasher (リーフラッシャー), he transforms into Ultraman Dyna by raising the object in mid-air.

During his childhood, Asuka's dad disappeared years ago when his space ship disappeared into a mysterious light. He spent his teenage years in high school as a baseball player and later on worked as a TPC maintenance crew in The Final Odyssey, saluting Daigo, who in fact his own predecessor. After enlisting himself as a ZERO Training student, he was accepted into the Super GUTS for being able to score high marks during their entry examination and saving Ryo from the Spheres by sacrificing his own GUTS Wing. During that time, he came in contact with Dyna's light and while fighting Darambia on Mars, this introduced Dyna for the first time. Although hesitating to use it again, he was able to overcome it quickly, embracing his duty as an Ultra Warrior like Daigo and fight against multiple monster and alien threats. In the three-part final episode, his identity as Ultraman Dyna was leaked and kidnapped by the Black Buster Squad to awaken the artificial Ultraman Terranoid, which eventually went rogue from Sphere's takeover. His kidnapper Gondo redeemed himself by sacrificing his life to replenish Dyna's energy and defeated Zeluganoid but Asuka collapsed from his injuries and was taken care by his predecessor, Daigo before Ryo picked him again. When Super GUTS unleashed a full campaign against Gransphere, he saved Ryo as Dyna from being held hostage by Neo Gaigaraid but during this point that his identity made known to his teammates. Despite Gransphere defeated by Super GUTS and Dyna's combined tactics, the battle came at a high price, forcefully dragging both Asuka and Dyna into a wormhole. While presumed dead, he was actually reunited with his long lost father and the two fly towards the space-time continuum, with Asuka eventually reappearing in subsequent Ultra Series installments.

Shin Asuka is portrayed by Takeshi Tsuruno (つるの 剛士) and Shunji Matsuzaki (松崎 駿司) in his childhood. Tsuruno is a fan of Ultraman 80, watching the series in his childhood and was once mistaken that said Ultraman would appear in Superior Ultraman 8 Brothers before Hiroshi Nagano corrected him. The original concept behind Shin Asuka is to have him as a baseball player but this was less focused due to Tsuruno having intermediate experience as a baseball player. His acting as Asuka left a huge impression to his eldest son, who has a habit of saying that his father's job is an Ultraman whenever people asked about it. While acting as Asuka, Tsuruno was reminded to portray himself as a teenager growing up. The props used to portray Asuka, such as his Super GUTS uniform and Lieflasher was nicely preserved under Tsuruno's own request, having expected to reprise his character in later years. Since Ultraman Dyna is a show that focuses on space, this left an inspiration to Tsuruno for his interest for astronomy.

GUTS
The Special Investigation Team GUTS (特捜チームGUTS) is the main attack team in Ultraman Tiga. Originally specializes in search and rescue, the team was changed into a monster attack team after frequent appearances of monster attacks, starting from Golza and Melba.

Ultra-Ancient Civilization
Unlike Showa Era Ultras, who were mostly from Nebula M78, Tiga ' s series mainly focuses on Ultra Warriors whose origin is from the Ultra-Ancient Civilization (超古代文明) of 30 million years prior.

A long time ago, this civilization was known for being a utopia, until the arrival of dark forces, which came in the form of rampaging monsters appeared and spreads fear towards its civilians. Then the light appeared to the cities' people, bestowed its power to selected warriors to fight against the darkness and restoring peace. However, as more warriors were turned into giants of light, a power struggle arose which split them into two factions. Soon, a civil war started between these two factions and as a result, several combatants corrupted after embracing the darkness, therefore destroying the very same civilization they lived on. One after another, the ancient civilization started to fall.

One of the strongest Dark Giants was Tiga Dark, but he switched sides after falling in love with Yuzare and sealed himself and his own companions within R'lyeh. In aftermath of the battle, leftover giants who survived the civil war were left to protect the Earth but when humanity fell under the influence of Gijera, the giants were unable to do anything and left due to their inability to interfere with humanity's decision. This gave the great darkness a chance to appear and strike the ancient civilization. The ancient giants left behind their Ultra DNA and powers (stone statues) for future generations to use in hope of the same incident that befall their civilization would not happen again in the future.

In The Final Odyssey, the remains of fallen combatants in R'lyeh donated their light to resurrect the defeated Ultraman Tiga as Glitter Tiga, therefore placing an end to both Demonthor and the dark influences from their civilization.

Land of Tiga Pyramid
The Land of Tiga Pyramid (ティガの地のピラミッド) was an ancient golden pyramid which serves as a final resting place for Ultraman Tiga and his two other companions before they left behind their stone bodies and left the Earth. As revealed in Ultraman Tiga Gaiden, this pyramid was situated near the Sakimori Village (which was later renamed as the Land of Tiga (ティガの地)), allowing Tiga's power to be utilized by Tsubasa and later Amui via a bronze Sparklence when the ancient sorcerer threaten the peace of their village. Said pyramid at that time was heavily disguised as a mountain while Jomonoid tried to destroy it. In the present day, (which took place in the first episode of Ultraman Tiga) Golza and Melba were awakened and contemplated to destroy the pyramid with the giants it houses. Guided by Yuzare's hologram in her capsule, GUTS located the pyramid but wasn't able to save it as both monsters destroyed it. When Daigo tried to defend the last statue from being destroyed, it was during that time he assimilated with it, bringing forth Ultraman Tiga to the modern era. The remains of destroyed statues were examined by Professor Yuji Tango, who in turn conspired with Keigo Masaki to search for another giant Ultraman statue in Kumamoto, leading to the birth of Evil Tiga.

As revealed in episode 49 of Ultraman Dyna, the remains of destroyed statues in the Tiga Pyramid was used by Gondo Kihachi to create his artificial Ultraman Terranoid.

In reality, Ultraman Tiga's first archetypal design was made in a form of a clay statue by Marbling Fine Arts company. Two other prototypes were also submitted by said company, and in the end one of them was chosen as Tiga's default design. The other two statues were however incorporated to the storyline as aforementioned stone bodies of Tiga's past allies that alongside him to protect the ancient civilization. Also, the original setting for the pyramid was instead supposedly to house five instead of three Ultras, with two statues being destroyed and the other two merging with Tiga to bestow him his Type Change abilities.

Evil Tiga
Evil Tiga (イーヴィルティガ) is a white-colored ancient Ultraman that appeared in episode 44 of Ultraman Tiga. Originally a giant of light whose statue buried under the Cytech Building in Kumamoto, he was discovered and had his powers utilized by Keigo Masaki, who like Daigo, a descendant from the ancient giants of light, but desired to use the ancient warrior's power to lead the human race with his own hands, having dreamt of humanity's destruction as well. He assimilated with Evil Tiga's statue via Daigo's Sparklence and his converter, which turn him into light particles.

But instead of leading humanity, Masaki's forced assimilation caused him to lose control over the giant, leaving Evil Tiga to wreak havoc within Kumamoto and attacked the Ancient Ultra's original companion Guarde until Ultraman Tiga appeared. While both giants fought to a standstill, Tiga performed the Brain Chop attack, which was enough to cripple the corrupted giant for the hero to defeat it. Although Evil Tiga no longer appeared, Masaki's formula in harnessing the Ultra's power led to the foundation of Project F in TPC. Prior to Terranoid's appearance, Evil Tiga appeared in episode 46 as one of the past enemies whose image was used by Moravia while using its powers to project its target's fears.

Being an ancient Ultra Warrior, Evil Tiga bears similar body features to the titular hero despite being differently designed, such as the forehead gem Evil Crystal (イーヴィルクリスタル) and Evil Protector (イーヴィルプロテクター) chest armor. His attacks are the energy blast Evil Beam (イーヴィルビーム), flying kick Evil Kick (イーヴィルキック), and defensive shield Evil Barrier (イーヴィルバリアー). His main finisher is the Evil Shot (イーヴィルショット), which is done in a reversal way to Ultraman Tiga's Zeperion Ray.

Evil Tiga is voiced by Takashi Kora in the series, who is also the actor for Keigo Masaki. He is a playable character in the video game Ultraman Fighting Evolution 3, where he is voiced by Yūji Machi (真地 勇志), Ultraman Tiga's voice actor and the narrator of Ultraman Dyna. In an original concept, Evil Tiga was meant to appear in the 2016 movie, Ultraman X The Movie under suggestion of writer Takao Nakano but was turned down by Kiyotaka Taguchi after finding the plot too similar to the original Evil Tiga.

Evil Tiga's design was improvised from a rejected design of Ultraman Tiga and was never referred to his real name during his appearance, ironically being called by Rena as a Tiga Impostor (ティガの偽者) despite his status as a genuine Ultraman. Evil Tiga's original proposal was meant to be a black-colored Ultraman, which was already made in conception by Hiroshi Maruyama since the first airing of Ultraman Neos (1995).

Although a genuine Ultraman, in the Ultra Series' 45th anniversary, Evil Tiga scored the fifth place in an Ultra Monster popularity ranking.

Ultraman Dyna
Ultraman Dyna (ウルトラマンダイナ) is the main titular Ultra Warrior of his own series, whose origin in the story remains unknown to this day. Dyna first appeared in the series as a mysterious light that bonded with Asuka after his GUTS Wing was destroyed, which left the man floating in space. When Super GUTS faced against Darambia on Mars, Asuka turned into a mysterious light and the Ultra Warrior made his debut on Mars, and killed Neo Darambia with relative ease. During that time, he was mistaken by a few people to be the long lost Ultraman, Tiga and was given an official name by Super GUTS' communication officer Mai (which revolves around the English word "dynamic") after other proposed names were rejected. Although bonded to Asuka, Dyna's entire activities were controlled by the man's own will, thus making him as the second case of "human Ultraman" (人間ウルトラマン) after Tiga himself.

From that point on, Dyna continued to fight against monster and alien threats when they could not be handled by Super GUTS or other military factions alone. Because of his appearance, he is regarded by many (both in-series and fans alike) as the spiritual successor to Ultraman Tiga, having met the latter once while the Earth was in the brink of invasion by Alien Monera. During his brief meeting with Tiga, he also inherited Tiga's light, further cementing his title as Earth's next protector. During the series finale, when the Sphires' invasion reached its climax, his host Asuka was kidnapped and Dyna's power was forcefully used to bring forth TPC's artificial Ultraman Terranoid. When a weakened Dyna faced his mockery, it was then when his host's kidnapper Gondo reformed by sacrificing himself to give Dyna the energy needed to fight back. His relation to Asuka was first exposed to Gondo, Ryo and the Black Buster Squad before the rest of Super GUTS discovered it as well when he tried to save Ryo from Neo Gaigaraid. With the help of Super GUTS, Dyna was able to save the Earth from Gransphire but unfortunately both him and Asuka were sucked into the black hole created from said monster's explosion. Although seemingly killed, Dyna and Asuka in fact survived and the two continued to travel in-between universes, first meeting with Asuka's long lost father, Kazuma.

Dyna possess the Dyna Crystal (ダイナクリスタル) that allows him to Triple Change (トリプルチェンジ), switching body colors and fighting prowess to his own preferences, based on Tiga's Type Change (タイプチェンジ). In every accessed forms, he retains the common ability to erect Ultra Barrier (ウルトラバリア), an energy shield that defends him from incoming attacks. Unlike Tiga, Dyna's version is limited, as in each transformation he can only switch to one Type before switching back to the regular Flash Type (default form). However, his advantages is that he is capable of accessing his alternate forms right during his transformation, as he did so when fighting against Deathfacer and against Graikis. His three forms include:
 * Flash Type (フラッシュタイプ): Dyna's default form, which bears the color red and blue and the Dyna Tector (ダイナテクター) chest armor. Flash Type is based on the original Ultraman's fighting skills and is an analogous to Tiga's Multi Type, both are well-balanced in performances but unlike the latter, Dyna is mostly agile and dynamic, hence the origin of his name "Dyna". Apart from that, his Dyna Techtor allows him to manipulate light energies into various beam attacks, true to the form's namesake "flash". His main finisher is the Solgent Ray (ソルジェント光線), which is performed in a similar manner to the original Ultraman's Spacium Ray but can also unleash a stronger variation, the Empowered Variant Solgent Ray (強化版ソルジェント光線), by spreading his arms backward in a similar manner to Tiga's Zeperion Ray. Apart from that, he can also utilize real life-based skills such as Ultra Fork (ウルトラフォーク), a forkball attack. In later appearances, he demonstrated other techniques, such as the healer-type Dyna Charging (ダイナチャージング) in Ultraman Saga and Spiral Burst (スパイラルバースト) in Ultraman Orb: The Origin Saga.
 * Miracle Type (ミラクルタイプ): Dyna's blue-colored alternate form, based on Tiga Sky Type as both focuses on speed. Unlike Tiga, who proficiens in aerial combat, Dyna possess the ability to perform ESP-based attacks, such as Ultra Psychic (ウルトラサイキック) to utilize telekinesis or Nature Control (ネイチャーコントロール) to manipulate natural elements to his liking. A variation of the latter is also utilized known as the Miracle Thunder Charge (ミラクルサンダーチャージ), which helps him perform electrokinesis. He used it once to recharge his energy via Kokakuchu's plasma lightning. His main attack is Revolium Wave (レボリウムウェーブ), which can be performed in two variations: the Attack Version (アタックバージョン) that banished his targets to a black hole or Reverse Version (リバースバージョン) that reflect incoming attacks back to his opponents. Alongside Cosmos' Luna Mode, this form is the foundation of Ultraman Zero's Luna-Miracle Zero.
 * Strong Type (ストロングタイプ): Dyna's red-colored alternate form; its color scheme being inversion to Miracle Type, as the red color dominates the most than silver and is based on Tiga Power Type, as both focus on brute strength. Compared to Tiga who also utilized range attacks, Dyna only has a little of them, and most of his attacks are strength-related. His only ranged attack is Garnate Bomber Shooting Version (ガルネイトボンバー・シューティングバージョン), which involves launching a spherical projectile towards the enemy or creating an Ultra Barrier to hold off the opponent's ranged attacks before launching it back to them. His known physical attacks are Vulcan Swing (バルカンスウィング), spinning his opponents in a high velocity or performing a Cross-Counter Punch (クロスカウンターパンチ) to defeat his impostor, Imitation Ultraman Dyna. He as well had an attack that was never shown in the series proper, called Garnate Bomber Swing Version (スウィングバージョン), slamming the opponent's head onto the ground. Alongside Cosmos' Corona Mode, this form is the foundation behind Ultraman Zero's Strong-Corona Zero.

Ultraman Dyna is voiced by Takeshi Tsuruno, the actor of his human host, Shin Asuka. In Ultraman Boy no Urukoro, he is voiced by Hiroshi Okamoto (岡本 寛志). In the Ultra Series' 45th anniversary, Dyna was placed 17th in the popularity poll and ranked 13th in 2013 with a total of 2301 voters.

Terranoid
Artificial Ultraman Terranoid (人造ウルトラマン テラノイド) is a man-made Ultra Warrior that appeared in episode 49 of Ultraman Dyna.

Created by TPC in secret as part of the plan F, Terranoid used the remains two destroyed statues that laid to rest with Tiga and used Keigo Masaki's forced merger with Evil Tiga as a basis. Requiring an Ultra Warrior's energy to activate it, Gondo ordered the kidnapping of Asuka and used Dyna's energy as it went into the action by fending off Mars Base against an army of Sphires. However, Terranoid's energy quickly ran out due to his inability to conserve energy and was assimilated/hijacked by the Sphires into a horrid monster called Super Synthetic Beast Man Zeluganoid (超合成獣人 ゼルガノイド). The creature rebelled against his own creators, forcing Asuka/Dyna to fight in a depleted energy until Gondo sacrificed his own life to replenish Dyna, allowing the giant of light to kill Zeluganoid with ease.

Terranoid's appearance is in fact based on Ultraman Dyna (particularly that of Strong-Type) with golden armor accessories. His main attacks are the Solgent Ray (Fake) (ソルジェント光線（フェイク）) and Beam Slicer (Fake) (ビームスライサー（フェイク）). As Zeluganoid, he retained his original attacks and is capable of utilizing energy shields and Flash Cycler (Fake) (フラッシュサイクラー（フェイク）), the former which is also demonstrated in most Sphire-related synthetic monsters.

Terranoid/Zeluganoid's grunts were recycled from Dyna's original grunts, who in turn is voiced by Takeshi Tsuruno, Shin Asuka's actor.

Ultra-Ancient Monsters
The Ultra-Ancient Monsters (超古代怪獣) were the main monsters of Ultraman Tiga. As their title implies, their origin dated back to the era of ancient civilizations, having attacked same location before being driven away by the ancient giants of light. Their shared feature are porous skin on their neck, which in reality were used to disguise the peepholes for the suit actors.
 * Ultra-Ancient Monster Golza (超古代怪獣 ゴルザ): Called by Yuzare as the "earth shaker" (大地を揺るがす怪獣), Golza was awakened within the grounds of Mongolia and join its partner Melba to attack the Tiga Pyramid and destroy Tiga and his companion's statues. Although being able to destroy the other two, once Golza was about to trample Tiga, the giant awakened after it assimilated with Daigo and fought both monsters. As the fight turned to Tiga's favor, Golza escaped and buried underground, leaving its partner Melba to be killed by Tiga. In The Final Odyssey, 5 Golzas appeared in the Ultra-Ancient civilization and terrorized it until they were countered by the ancient Ultra Warriors. Golza's main ability is Ultrasonic Ray (超音波光線), which involves launching ultrasonic beam from its forehead. Golza is designed by Hiroshi Maruyama, with its face resemble that of Geronimon from Ultraman and original motif is based on Gomess from Ultra Q. Its original name was Orugo (オルゴ) before being changed to Golza.
 * Golza (Empowered) (ゴルザ（強化）): Months after escaping from Ultraman Tiga, Golza buried itself into a volcanic area where it consumed the heat from its surroundings and evolved, gaining enhanced strength and firepower. Awakened by GUTS' attempt to stop said volcano from erupting, Golza went on a rampaging spree in its nearby area until Tiga appeared and killed it after a brief fight.

In the present day, Gatanothor awakened several days after Gijera's destruction, bringing forth the sunken island R'lyeh to surface and unleashing its vanguard Zoigers. When Gatanothor's darkness began to spread all across the world, Tiga fought it but was quickly defeated due to its sturdy armor and gigantic body. Tiga was later turned into a stone statue before sinking into the depths of the sea. Eventually with everyone's lights around the world, Tiga was momentarily revived as Glitter Tiga and turn the tables to defeat Gatanothor, therefore restoring peace to Earth.

Space Orb Spheres (宇宙球体 スフィア) were the main antagonist of Ultraman Dyna. Their first appearance was during the Super GUTS training enrolment, attacking ZERO cadets and Asuka sacrificing his GUTS Wing to save Ryo. During its attack on TPC Mars base, it was then where Dyna made his debut and destroy several Spheres before fighting against Neo Darambia. While having fewer appearances in the series, they were soon given an active involvement in the three parter finale episodes, combining with each other to form Dark Planet Gransphere (暗黒惑星 グランスフィア) and contemplated to consume the whole Solar System. Having consumed Pluto and the artificial sun, Gransphire set its target on Earth, using a black hole as its shield until Super GUTS in Clarkov fires the Neo Maxima Cannon for Dyna to finish it. But Gransphire's death came at a high price, as Dyna/Asuka was absorbed into the black hole. In Ultraman Saga, it was revealed that several Spheres survived and tried to attack the TPC Mars base once more before being countered by Nozomu Taiga and being captured by Alien Bat to feed his Hyper Zetton.

Neo Geomos' barrier grew stronger despite GUTS Eagle and GUTS Wing equipped with anti Maxima cannon. However, Munakata's arrival with the GUTS Wing EX-J which equipped with a further enhanced anti Maxima cannon turn the tables for both Ultraman and TPC officers to attack. Using Strong Type, Dyna threw Neo Geomos in mid-air for all forces to finish it at once.
 * Blazing Synthetic Monster Graikis (灼熱合成獣 グライキス): Created when a Sphere assimilated with Ice Venus, artificial bacteria developed by TPC as part of terraforming Venus. Instead of being destroyed, Dyna separated the Sphere fragment, allowing the monster to revert into the Ice Venus once more as it rained on the Venus surface in a similar manner to snow.

In Ultraman Dyna: Return of Hanejiro, the Alien Miji was captured by Super GUTS, which simultaneously took place in Dyna's defeat by One-Z. To escape death penalty, they offered their alliance and used Pochi Garaon to do so by having Hanejiro deliver it to One-Z and freed Dyna, as well as killing Casa Madara, the android that manipulate the monster.
