My answer:

First thing is, I would want to fly. But not into space,
just around the planet. I would also go on inviso power, so I could have time to train. I'd never want to reveal these abilities if I hadn't trained to use them first.

So hopefully my ring would've called Kilowog and I could go to Oa or he could come here.

So first on my list would always be Power Mastery.
