Name would be Rex Dark. As for my plans, if I told you them, you might attempt to use that information to stop me, at which you would fail, but you would be too much of a distraction when executing may plans, possibly forcing me to delay my plans again.
But here's one plan I could use anyway:
-Build missile silos under roundabouts all over the world.
-Fill missile silos with nuclear warheads.
-Hack into TV satellites to transmit me on every channel worldwide.
-Broadcast evil monologue followed by evil laughter.
-Broadcast me pushing a Big Shiny Red Button of Doom from inside a spaceship on the one rocket without a nuclear warhead while all the nukes launch (they'll never be able to find out which one I'm in).
-Launch into space and watch the fireworks from a safe distance.
Optional part to do after watching the fireworks:
-Realize I forgot my cheesy snacks.
-Turn on top view internal camera.
-Put my hand in the air.
-Scream "Nooooooo!".
Actually it sounds rather fun, I think I'll try that plan sometime.
