[@The_written_John]I'm a little iffy about space and time manipulation. At first I skimmed your character sheet expecting the Doctor, and I definitely could've used a guy with some neat gadgets who knew how to fix things. Your character's powers, however, are far too much for the party. I don't like letting my players use characters they don't like though, so how you tone it down is your choice entirely. My only judgement is that you nerf it somehow. Everything else looks good though. I could argue that the scope of his goals are also far greater than most of the other party-members, but I can easily adjust to that, and it's not like I wasn't planning on epic-level adventuring anyways.

Nerfed the powers. Besides, its not exactly overpowered, he cant freeze time, he can slow his foes, speed up his allies and assault his enemies with spacial rock and magic stars, i think ive balanced it well. 

No healing or damage over time abilities, nexus vaccume is now only a bag of holding and doesnt do damage.

Shrunk the comets size conciderably

I assume this is nerfed enough? After all hes mostly about damage and isnt very well protected, so he needs to have some power. It should be nerfed for your rps standards however.
