Mitch, A.K.A. Experiment 173, is an illegal genetic experiment created by Jumba Jookiba. She is designed to be the leader.
Experiment 173 was the 173rd genetic experiment created by Jumba with Hämsterviel's funding. She was designed to be the leader.
171 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
All of the experiment pods were released and scattered across the island of Kauai.
She works with Rich (171) and Ditch (172). When Jumba was making 171 the embryo split into 3 so she only has 2 of the 6 powers she was supposed to flight and a lethal sting. She is neutral but tends to choose evil because of her brother 172.
At an unknown point, 173 was activated, captured, tamed, and named Mitch.
