Wizpig

"Well, lookie here! It's the little worm!"

- Wizpig, Diddy Kong Racing 

Wizpig is a gigantic, pig-like, alien sorcerer and the main antagonist of the game Diddy Kong Racing. Not much of Wizpig's past is known, except that Wizpig, bored, decided to conquer his own planet. Succeeding in this endeavor, Wizpig forcibly transformed his home world into a high-tech amusement park (for his own pleasure) called Future Fun Land. Eventually, Wizpig once again, grew bored and decided to leave his planet to look for thrills on other inhabited worlds. One of the thrills Wizpig discovered was racing, this sport eventually became Wizpig's favorite thing to do, along with causing chaos.

From then on, Wizpig went from world to world causing destruction and racing those who were brave enough to challenge him. After a while, Wizpig would grow bored of the planet he was on and would eventually leave it, possibly destroying it after he had his sadistic "fun" on it.
