Greenzilla is one of the very worst outlaws and, as such, is kept on one of the very few solitary confinement cells within Sledge's ship. His tentacles sometimes can escape the reinforced cage and wrap around those outside. Sledge himself describes him as his most dangerous monster. He has momentarily ensnared both Wrench and Poisandra before letting go due to damage to the appendages.
- Greenzilla can launch his appendixes to trap and entangle enemies.
