Re: Why that costume
For any of the characters I've come up with, the costume design is almost random in some ways. I just come up with a look I feel suits the character, sometimes the color scheme has some relation to thier powers. Spectrum for example has a yellow and black costume, the yellow due to his light powers and the black....well I just thought it looked cool.
They have no in game reason for thier costumes (mainly due to the fact that I haven't been in a game for quite some time), except for Shadowfist. He was a ninja, that pretty much dictated what he would wear from the instant I came up with him.
