Here are some... don't have pics to compare all of them, sadly and some are actually new chars to Champions universe
Condor:
This one was very easy to translate from oen game to the other, only thing missing are proper shields on Champions.
Violet Darkmoor:
There was no way to make the hooded costuem look right without glowing aura for the eyes onChampions... so I went into making a completely new costume but keeping the theme. I think I did it quite nicely.
Psychic Silk:
Same with Silk here... sadly I could not replicate the awesome purple costume, so I went to something that captured her spirit.
Anemona:
This one was easier than the others, I just had to check how Atlanteans fit on Champions universe and made some minor adjustments.
Puma:
Another one that was easy
Tralka:
This one needed some work but basic colors remain.
Ok... I hope that was not too much
