Scenario 1: I hang out in space a lot, and take advantage of being able to fly and teleport and such. I go to a far, far part of the galaxy to blow up an empty planet or two for the pretty explosions just because I can, then come back and go to work in the morning. Chances are, I don't actually make much practical use of my abilities other than never needing a car again. I guess I do a lot of world travelling too, just because I can.
All of that dependent on my being able to convince people that I am me, and figuring out some kind of excuse for having a solid purple eye and blunt purple spikes sticking out of my forehead in a line above said eye. If not, I guess I bum around and take advantage of not needing any necessities, like food, air, water, or protection from basically anything and just hang out wherever I feel like. I hear the core of the sun is nice this time of year.
I definitely try and practice until I can use a small enough amount of power throwing beams and booms around that I'm not accidentallying the city a hundred miles down range, if I can't already. I probably already can though, so not much of a problem really.
Scenario 2: I try and figure out a way to get Tokimi to treat me nicer. Maybe make a fuss of things without going as far as Z did in canon, to get her to decide to do so on her own while hopefully not getting myself gibbed by Tenchi awakening as ubergod like Z did. It might end up with me becoming Tokimi's husbando with no choice in the matter, but that should be acceptable.
