Well. Telepathic powers could be nice. But then I would hate people more than now. Msybe not.
Teleportation would be nice. But I would use it steal stuff and probably be stupid and someone would kill me. So no.
Perfect heath and super-luck would be nice, but dunno. I lost my faint to good luck and heath many years ago, so I don't think it's my thing.
What I really would like to would be to grant other people's wishes. And ability to twist them. When again, people would ask stuff that would cause bad stuff for them anyhow so I would take it it anyhow. Yep I want to be evil genie of legend who sometimes is nice for really nice people. Mmh I can do this, in indirect kinda ways.
Ah there are other things. I want to be young again and have power "have faint in myself" again.
Or to be really talented at languages and mathematics and all art stuff. Or even one or too. I am painfully avarage.
I also want to kidnap often random punch of people in train/buss to some random fantasy world. And watch what my test subjects do, while suffering myself. I would hate that. Ah but to witness reactions of 30+ people would be totally worth it.
I want to remain forever as bodiless, dispassionate ghost to be able to witness the end of the universe. After this life naturally. Not in any hurry to that quite apperently.
I've thought up various interesting superpower options, alas only rally lame ones are available in this universe.
