Norm

Norm is the weirdest character from Nitro Kart because he can divide himself into two different characters, small Norm and large Norm. They both wear berets and the big Norm is the talker while the small Norm never even speaks, small Norm seems to be a mime. They both don't like losing. Emperor Velo takes away small Norm's books because he doesn't follow Velo's command to race the first time. They both don't like losing and are the penultimate boss the characters face before racing Velo. You can unlock big and small Norm from the GameBoy version by finishing the race first place against them in Out of Time.

Trivia

 * Norm and Velo are the only characters in the series who are both really big and really small. This blows the mind of several fans for undisclosed reasons.
