I may have overpowered this guy. I don't really care, I put a lot of thought into this. ( I can get really bored)
Meteor-kinesics: I would have control of the weather, specifically making any kind of storm (except highstorms, I'm not going there) Anyway, this would allow me to fly, as I could control wind. Oh, and if I could get the power to create lightning from my hands, awesome. (Changing the lightning's color would be doubly cool.)
Bottomless Pockets: I would be able to create wormholes between any two dark spaces, preferably enclosed. Thus, I would wear a cloak, and whip out weapons and other things from the robe (storing them in secret caches, of course) The cloak could also serve to allow me to simply pull up the hood, and teleport to somewhere else, though I would prefer simply disappearing down a dark alley.
Forcefields: These aren't normal forcefields. I could get really technical with this, but basically, ten seconds after the forcefield is damaged, it gets stronger proportional to the damage done in the first second, then the second, and so on until ten seconds after the attack stops. However, the larger the field grows, the weaker it is, and if it gets shattered by too much force at once, then I have to start over. There are some formulas I could put together for this. I will abstain for now.
For the outfit, I would wear a suit of metal armor all over, but thin and light enough for me to easily move around, since it's mainly ornamental. The robe would be blue with bright, almost neon green ( go onto Paint and set the green to 255, and Red and Blue to zero. That's the color.) I would likely have a bunch of lightning-powered weapons, like a quarterstaff or spear, sword, etc. If I couldn't get lightning shooting out of my hands to power this, I would just make tech that did the same thing.
And now for the name. I thought of this Epic before I made my 17S account, and chose the name of my account to match my Epic's name. Yeah, my Epic's name is Stormgate. I also use it as my character's names me on RPGs, since Stormgate is usually never taken.
Oh yeah, what would set me off... I honestly don't know. I don't often get angry, so I don't have enough experience with it to figure out how I get ticked off. As an older sibling, probably the continuation of an annoying activity after a request for it to cease.
