Why the hell has no one posted Thorion yet?!?!?!
What do you mean by powering up?
Well, not in the sense as DBZ or anything, but their was a space ship on the moon which belonged to an alien race. Orion decided to destroy it with the Astro Force on the moon, but in doing so would have torn the earth apart.
Orion's Astro Force was also capable of containing the Oblivion Bomb's energies, which was powerful enough to destroy the universe.
