This is pretty cool stuff so far. I do have one comment, though - you might want to rethink having so many heroes wear outfits with such a similar color scheme. Fusion, Captain Stupendous and the Riveter are all wearing purple, the silver on the latter two costumes is reminiscent of all the white on Fusion, and her black hair ties in with the black outfits of Stupendous and the Brooder. Don't get me wrong - I like the costume designs, and I hope I don't come off as overly critical - it's just that there's very little color variation so far, which can make characters difficult to tell apart. If you get a chance in the future, it might be a good idea to vary their color schemes a bit.
