* CreatorsApathy: The writers openly admit the "Thor" segment was just to showcase how awesome Hulk is.
* FakeNationality: Ironically enough, despite most of the voice cast being Canadian, three of the four prominent Canadian characters in the "Wolverine" segment ([[Creator/StevenJayBlum Wolverine]], [[Creator/NolanNorth Deadpool]], and [[Creator/TomKane the Professor]]) are all voiced by Americans, with only Sabretooth actually being voiced by a Canadian voice actor.
* TheOtherMarty: Deadpool was originally voiced by someone working for The Ocean Group, but the producers didn't feel he worked very well. They then brought in Creator/NolanNorth (who was already working for them in ''WesternAnimation/WolverineAndTheXMen'') and had him improvise lines for Deadpool.
* ThrowItIn: Most of North's dialogue for Deadpool was improvised as a result.
* WordOfGod: The producers have said that the "Wolverine" short, ''WesternAnimation/WolverineAndTheXMen'', and ''WesternAnimation/TheAvengersEarthsMightiestHeroes'' take place in the same universe despite all the continuity errors that seem to say otherwise. However, [[GodNeverSaidThat they said no such thing about the "Thor" short]].
