I could see how Penguin is one of the first to come to mind on account of his flip-floppy ways, with his successor being Emperor Penguin, but that's not who I'm thinking of. I'm willing to give clues but I want to save the most obvious ones for last.

Here's a hint though, both the successor and the original share the alias. One was not operating at the same time as the other.
