K. Rool was the anti-Bowser. While Bowser for the longest time was this super-generic dragon villain, K Rool at the time oozed personality, in terms of the many roles he undertook (king, pirate captain, technology expert, boxer in DK64). K Rool can be seen as the model for what Bowser slowly grew into, a more dynamic villain with a lot more to say about himself than "Capture Peach rawr!"
That said, he's still a bit overrated, but there is certainly much to be said for him.
Monster Hunter: pissing me off since 2010.
