Re: Avengers Assemble! Animated Show - Part 1
Well some characters on Earth's Mightiest Heroes did change outfits from time to time. Thor's outfit changed in season 2. While he was a Skrull, the Skrull Cap wore an Ultimate style costume. Iron Man changed his main Iron Man suit. I think Hulk even started wearing different shorts.
Surprisingly Wasp never really changed outfits when her character had the reputation of changing her costume like every other month in the comics.
