Case in point: After first discovering this world changing energy source, he makes exactly one more arc reactor, and uses it to power his pizza-colored murder suit.

Wait a second. Who throws away the only backup power source for the machine that's keeping him from having a heart attack?
Comic books have a name for brilliant scientists with nearly debilitating Messiah complexes. They're called supervillains.
