So. I have this lovely psychonaut reserved; my question is, how much of his psychic powers would he be allowed to retain? Pokemon, as you've said, does allow for some of it. I was thinking just his telekinesis and perhaps very limited clairvoyance (the ability to see through other people's eyes). If that's too much, just telekinesis or even stunted telekinesis would be fine.

Also, I was wondering if there would be any possible way to keep his skin it's greenish hue. My backstory for him so far involves him having grown up in Magnolia and then going to live in the forests surrounding it to research the pokemon there; I had a half-formed idea of some of the plants he used for food turning him green, but that just sounds ludicrous.
