| Bomb Guy
| Character Information
He is a humanoid character with a bomb for a head. He has also been styled to resemble classic cartoon characters, such as Mickey Mouse, wearing white gloves, similar two button shorts, along with a bow-tie. He is also monochrome to match the style.
He is shown to take charge, as he gives orders to Gumball, Darwin, and the Pink Bear. He is also shown to be quite smart, as he was able to plan an escape from Elmore Junior High, using Gumball and Darwin as scapegoats. At times, his "head" lights a fuse, usually due to anger. Once he explodes, his head is replaced with a much smaller bomb, thus making his voice really high and squeaky. He also appears to still have a grudge with Gumball and Darwin as he is seen along with the angry crowd attacking the Wattersons inside their house at the end of "The Finale."
