K.O. the Kat is one of the bosses of the cancelled Twelve Tales: Conker 64.
He is a giant purple cat with a striped t-shirt, a purple turtle's head on its front private parts and is armed with a hammer similar to Thor's Mjölnir.
It's more likely that his name is Knock Off the Kat, due to his hammer that could knock off someone.
- "Come on, ya little squirt!"
- "Where ya runnin' to?!"
- "Take yer best shot! Ha ha ha!!"
- "Hurts, don't it?" (After flattening either Conker or Berri)
- "You won't beat me like that." (speech bubble)
- The name was given by Rare official website DK Vine.
- His real name is confirmed in the Nintendo 64 magazine.
