Kixx

Experiment 601, later known as Kixx is a very ill tempered, four armed, musclebound fighter; his personality is basically like any of Dr. Jumba Jookiba's 600 series experiments: excessively violent. Physically the most powerful of all creatures in the series, this big purple monster loves to fight and has the strength to hold his own against a rebooted 626, as well as being able to easily lift and throw a full-grown man and trash a small car. After his defeat and subsequent rehabilitation, he now works as a fighting instructor on Earth.
