King Koopa's alter egos

King Koopa's alter egos are the many aliases utilized by King Koopa throughout numerous episodes of The Super Mario Bros. Super Show! With a few exceptions, an alter ego involves both a special costume as well as a different name. Aside from cosmetically fitting the theme of a given episode, no real reason is given as to why King Koopa uses these alter egos, as they don't conceal his identity in any way. It's possible that King Koopa just uses them for the pleasure of it.
