I'd either control space and time, like Hiro Nakamura in Heros, or have the power of physic persuasion. Kind of like Matt Parkman in Heros.
With time and space, I'd fukk with people. Moving things that were in front of them, and watching them go "

" after they can't find it. I'd be able to slow down time, while I'm moving normal. I'd, also, be able to teleport.
I'd go all vigilante with it too.
First stop, Chicago.
I'd get the real Batman outfit, and have a ball. I can't fight like Batman, but the powers would make up for that. nikkas would think I was FAST AS HELL, so it would seem like I was a crazy good fighter. I'd really scare the shyt outta nikkas. nikkas would be like "The Batman is REALL!!!

And he's BLACK!!!

"
If I went with the physic persuasion, Id be able to project my thoughts on others.
With that, I'd collect decent sized, lumped sums of money from a bunch of celebrities and SUPER rich people.
Or maybe, I'd go into a big corporation and tell them I want a job. Then make them pay me a CRAZY salary to do nothing.
I'd take my nikkas to the club, and put them on so much p*ssy too. lol Every bad chick that came by, I'd be like...."Aye, love. Why don't you go fukk my mans real quick" My nikkas would be like "How yoube doing that shyt, Sims?

"
I'd also try and kill some of the corruption in the government. Straight go and figure out who's bribing who, and make them stop.

Straight kill the lobbyist game, almost.
I wouldn't use my persuading on everyone though. I also wouldn't tell anyone about it. Especially people close to me. I wouldn't want them to feel like I use it on them.
I might plant a few good ideas in peoples head, though. Like, makin some nikkas go to college, and stop pushing nik bags of weed. lol
I'd probably use it to get a lot of p*ssy, but I wouldn't use it on the girl I was really feeling though. After a while I'd get married (who knows...fukkin random girls ALL the time might get old

). I might use it on my kids though, if they started fukkin up.
I could go on and on with this. lol
