-Mutagen [Scientist x Hybrid]
My character's a recluse who lives on an island and does experiments. He accidentally releases a mutagen which turns animals into hybrids of various sorts. Your character would be a half-human hybrid who has a crush on him and tries to follow him around while he tries to contain the genetic disaster to his island.

-Time Travel:
My character is a time traveler from 20 minutes into the future, who gets stranded in a previous time period. Preferably, a very long time ago (Ice age to medieval, I was thinking). Your character is a lady native to the time period who teams up with my character, to go and fix his time machine.

Both of these sound interesting if you wanna RP I would like to do either of these. I have an idea on what to use for the time traveling one.
