About Marvel Super Hero Squad

The Super Hero Squad Show is an American cartoon series by Marvel Animation. It is based on the Marvel Super Hero Squad action figure line from Hasbro, which portray the Avengers, the X-Men, and various other characters of the Marvel Universe in a cartoonish super-deformed-style. It is also a self-aware parody of the Marvel characters, with influences taken from on the comedic Mini Marvels series of parody comic books, in that the heroes tend to find themselves in comedic situations, and have cartoonish bents in comparison to their usually serious personalities (such as The Incredible Hulk being jovial and good-natured but with major anger issues), and is an overall comedic take on the Avengers. The series' animation was produced by Film Roman and Marvel Animation.

Comedy is the driving factor of The Super Hero Squad Show, and the members of the squad have a comedic bend that parodies their usually serious personalities and their powers:

Iron Man is obsessed with high-tech solutions for even the most mundane of tasks, and his newest gadgets tend to either go untested or blow up in his face.
The Hulk is childlike, good-natured, and even jovial, but is prone to major anger issues that lead to unintended mishaps. He owns a massive collection of comic books, and tends to get into juvenile arguments with The Thing from the Fantastic Four over which one of them is stronger. He also has a strong aversion to water, due to his heavy weight, which causes him to sink like a rock.
Thor is overly enthusiastic about everything, and the other members of the Super Hero Squad sometimes cannot understand his archaic English.
Wolverine resents being a mentor to Reptil, choosing to go it alone, yet concedes they make a great duo. He also hates being nicknamed Wolvie. Whenever he is badly injured, he always refers to his adamantium skeleton (curiously, his healing factor is not mentioned).
The Silver Surfer talks in a stereotypical surf culture accent, uses typical slang associated with surf culture, and likes to engage in philosophical discussions.
The Falcon is often paired with the Hulk, who calls him Bird, and is like a big brother or mentor to him in that he either keeps the Hulk from losing his temper or frequently reminds him of the task at hand.
Captain America frequently uses phrases or thinks things that imply he believes he still is in the 1940s (for instance, mentioning Franklin D. Roosevelt when referring to the President, or shocked when he sees karaoke, as that was invented by the Japanese, and the other characters explain to him that they made up a while ago). This is a reference to his classic origin: getting frozen in ice during World War II, and then getting unfrozen during modern times. In addition, he has been present at various events in American history (though how he witnessed these events is unclear and not explained), and will tell the others about it in full detail unless they keep moving.
Scarlet Witch is a former villain and stowed away on the Helicarrier thanks to Falcon before being accepted as a member of the team.
