Beast Boy (DC)

The Changeling of the Teen Titans, though in several universes he's a major perv so it's not surprising if he got the power.

So what universe? Is he in the Titans, Young Justice, the Doom Patrol, solo?

Does he know other heroes?

How did he get the power?

Does he get corrupted the more he uses it?

Does he have a limit to what he can do?
