Monokid is a child-like robot. However, he also has a very bad mouth and a short temper, and he's considered the hooligan of the group. He is a noisy and vulgar bully. He enjoys rock music and playing his guitar, and occasionally shouts exaggerated high-pitched screams like a rockstar. He also apparently loves eating salmon and especially honey, which for some reason can make him drunk and mutter nonsense.
