I read through the stories and came to love this idea. Definitely interested!Also, I was thinking of my character being a Sense Manipulator with a touch of Imperceptibility. Contemplating being a 100% full pure human female.

Perception distortion would be a good ability for one of us to have. There aren't any really big differences between pure humans and your run-of-the-mill few-non-human-chromosome normal humans.
1) Pure humans tend to have wider array of possible powersets, as any non-human DNA skews the possible sets towards the race it is from.
2) Theoretically, pure humans can adapt faster than non-pure, but that hasn't been tested.
3) The racist people who think non-humans are evil will accept a pure human much more readily than a non-pure. Also, they won't have kids with non-pures.

I'm thinking of making a guy with Kekkai (spherical barriers that are good against physical attacks, poorer than average against energy) and a rogue power of "sympathetic healing" (link our subconscious so that I take your pain, emotional or physical, and boost your immune system and healing rate).
