Not really. How are we insane?
K. Rool is just as awesome as Bowser in many respects,
1st. Theyre both comical villains. Both bumblers who have crazy bumbling henchmen.
2nd. He is DK's EQUIVALENT to Bowser. (Bowser is a turtle, who orders other turtles around, and kidnaps something of value to Mario, and his plans are always foiled in the end.)
K. Rool is a croc, who orders around other crocs, he steals DK's bannanas, etc. etc.
Starting to see the similarities?
K. Rool had more right to be playable than many of the other "shoe ins" except maybe Ridley, because come on... Metroid is in need of another rep.
Is your reasoning for not liking him SamuraiPanda's reasoning? He's ugly?
Well, if he was supposed to be adorable, or sexy (lol) or something else, he wouldnt have the same effect he does in the games, nor would he have the same personality.
Rare doesnt work that way. Rare creates far-out villains and situations and monsters (Every inanimate object in Banjo-Kazooie and Conker had huge staring eyes, Banjo's enemy was a rhyming old hag, yada yada)
K. Rool should have been in, and it's a shame he isnt, but I respect Sakurai's decisions anyway.
