Upon further review, it looks like this is the person you referenced:

However, I am trying to keep the characters consistent with Marvel comics. The primary reason is to give me a common reference point for creating the powers/abilities for each of the characters. I have a reference site that is extremely helpful with this. The secondary reason is that I can put together a better story if I know something about the characters and their shared history within a common Marvel universe.
