[@GamerXZ] That's a really good question, thanks for bringing that up.

1. Shit people are already doing, it would make the RP a little less fun. Variety is the spice of life <3
2. Anything that make any conflict a cakewalk for the character. They can become more powerful to the point where it will be a cakewalk for them, but don't make them start off too powerful. This can be overridden with behavior (like the person is a pacifist and will show restraint to not kill his enemies... a bad example but an example nonetheless). Depends.
3. Any power that will destroy planets/universe/moons/cities/whatever.
4. Any power that will destroy the RP itself, whether it would halt the RP or just make the RP no longer fun.
5. I don't know, just whatever I see that could cause a whole lot of problems. I'm GM, and my word is [url=https://www.youtube.com/watch?v=q6cyDsuNx_U]LAWWWWWW!!![/url] 

I hope this helps, I hope I don't come off as too strict. :(
