Doombox is an out of control experiment that escaped and took control of the first machine it could find - a classic boombox. He has a tendency to go berserk for reasons unknown. His reasons for playing in the Lethal League are likewise unknown.
Doombox can hover and fly in multiple directions. Doombox can only hover for about 4 seconds before needing to land. Doombox's special move targets an opponent and launches the ball straight at them. Doombox can bunt out of his special. Doombox can also push opponents away, and launch the ball in a straight line from which direction he is looking, by crouching and pressing jump.
- Doombox is playable in Lethal League through a cheat code that can be entered in Challenge, Versus and Training Mode. The "code" consists of selecting the characters Sonata, Raptor, Switch, Candyman, Raptor, Dice, and finally Latch. Upon selecting Latch, the player's character will set as a question mark, as Doombox has no character select image1.
- The achievement "Doombox slam dunk" can be earned before unlocking achievements for beating the challenge mode as regular characters if they have not been unlocked, and you beat the challenge mode as Doombox without using continues.
- According to Dion Koster, Doombox's design is inspired by the Lasonic TRC-931.
