Well in my case Miyuki is based on the speed type trope because I thought it might be fun; who doesn't like fast girls LOL

Elliot is another matter because she's modeled around two unusual powers that are seldom ever considered for heros. I was also trying to figure out how to make an effective yet nonviolent sort who's ability would be useful to a team.

Elli's primary power is her ability to see into the past by touching objects and people, this makes her an invaluable forensics investigator who can see the crime as it happened and even track the person or persons 

Her ability to be able to speak any language or understand them means that when people talk in her retro visions she's able to understand what was said

I was toying with giving her the ability in the future of being able to project what she sees as a limited illusion (the limit being that she can only show what happened an not alter it)
