Marvel Adventures: The Avengers

Marvel Adventures: The Avengers was a comic book series published by Marvel Comics that began in 2006. The series has no direct relation to the history of the mainstream Avengers comic titles or its characters. Like the other Marvel Adventures series, the series is aimed toward younger audiences. The series was canceled in 2010 when the entire Marvel Adventures line was revamped.

Avengers

 * Captain America (Steven "Steve" Rogers) is a super soldier from the second world war who was frozen in ice, but defrosted decades later to join the team. He has greater strength and reflexes, as well as wielding an impenetrable shield. He is the leader of the Avengers. He was created by Joe Simon and Jack Kirby.
 * Iron Man (Anthony "Tony" Stark) is a billionaire who wears a suit to ensure that the shrapnel that impaled him during an attack would not reach his heart. At the same time, the suit contains various weapons and has various models. He was created by Stan Lee, Jack Kirby, Don Heck, and Larry Lieber.
 * Storm (Ororo Munroe) is a mutant who controls weather, and also creates electricity. She is the second-in-command after Captain America. She previously joined the X-Men. She was created by Len Wein and Dave Cockrum.
 * Hulk (Bruce Banner) is the scientist of the group, and turns into a giant, green superhuman after a gamma radiation incident. He was created by Stan Lee and Jack Kirby.
 * Wolverine (James "Logan" Howlett) is another mutant who has retractable claws, high sense of smell, hearing, sight, and of course healing factors since birth. He has a painful past as he was a Weapon X test subject, which gave him an adamantium skeleton. He also previously joined the X-Men. The Avengers wonder why he is very grim and selfish at times, but many times his past is the main reason. He was created by Len Wein, Herb Trimpe, and John Romita, Sr.
 * Spider-Man (Peter Parker) is a normal graduate and photographer for the Daily Bugle that was bitten by a radioactive spider, and was given wall-crawling, web-shooting, super-strength, reflexes and enhanced agility abilities, and an ability he calls spidey-sense, which he uses to warn him if he is in danger. His origins as Spider-Man resulted when his uncle Ben died. He carries his uncle's last words with him everywhere he goes: "With great power, comes great responsibility." He has a witty sense of humor, and at most times he jokes along with Giant Girl. He was created by Stan Lee and Steve Ditko. Ironically, he was supposed to join the New Avengers.
 * Giant-Girl (Janet Van Dyne) is a scientist who, with Pym particles in a machine, grows taller to about sixty feet. She is the strongest of the Avengers having strength enough to hold back landslides and to catch a school flying through the air. She is later, with the help of a new suit, able to shrink down to diminutive size and calls herself Wasp. In this form, she is able to fly, has proportionally superhuman strength, and can fire bio-electrical stings from her hands. Originally, she was vulnerable to insect mind control, due to her suit's insect controlling mask. After being freed from the mind control, she crushes the leader of the dangerous plot with her boot. The suit with these capabilities was eventually replaced, and she eventually receives a new suit that lacks the insect control feature. Giant Girl seems to have humor similar to Spider-Man's, and sees the team as family, even enveloping them in a giant bear hug after nearly crushing them. Instead of primarily using the Wasp identity, she typically uses the Giant-Girl persona. She was created by Stan Lee and Jack Kirby.

 * M.O.D.O.C., or the Mental Organism Designed Only for Conquest, used to be an A.I.M. agent. They were working on a project and needs a human to complete it, thus he was chosen. He wishes to conquer the world. He turned the Avengers into versions of himself after battling them, but was ultimately stopped, and the Avengers turned back to normal.
