Kaia is an eco-activist as well as the leader of Terra. She is one of the main antagonists in Motorcity. She is voiced by Laraine Newman.
Kaia is the leader of an eco-friendly resistance group called the 'Terra', who live in a village outside Detroit that was destroyed by Kane Co's waste dumping and fight using rapidly-growing mutant plants as their weapons to take revenge on Kane as well as the Deluxe population. As a side effect of the dumping, the Terra themselves had been mutated and are forced to conceal their appearances behind gas masks. While allied at first, Kaia and her followers are now enemies of the Burners, primarily because of the Terra's attack on innocent Deluxe citizens.
- Kaia is seen as a dark image of Mike.
- She has the trademark broken lips of other Terramembers, but also has a third eye hidden by her headband.
