Depends on my power level. If it's above-average/street level, I'll just keep on living my shitty life as if nothing had happened. If it's cosmic/OP levels, I'd actually do the same. Too much effort/unwanted drama otherwise.
... On a second thought, I'll probably rob something regardless of my power level so I can be rich and do nothing but travel around the world (or Universe).
Fuck being a hero/villain. Too much work and too much drama.
