|Green security guard
The guard is a green humanoid. He wears a tan shirt and a brown pair of pants with black stripes (one stripe per side), as well as a blue necktie, a belt, a pair of black shoes, and what appears to be a badge or yellow patch near one of his shoulders. In "The Safety," he can also be seen wearing black arm pads and a SWAT-like helmet.
The green security guard is fairly dutiful in his job. In "The End," he stops Gumball, Darwin, and Richard from running in the mall, and thus from breaking the rules. He also tries to prevent Nicole from passing through a "vehicles only" entrance in "The Mothers," though to limited success.
- "The Mothers": He tries to stop Nicole from entering a parking garage.
- "The Safety": He is part of Darwin's new police force.
