Monzo
- Monzo is a Decepticon-allied Nebulan Headmaster from the Generation 1 continuity family.

On Nebulos, Monzo was a professional hyperwrestler. He's a feral fellow who doesn't appreciate the fine art of tactics or strategy. He especially hates poetry, which puts him at odds with his Headmaster partner, Weirdwolf. However, they both find common ground in wanting to beat stuff up.
Fiction
Marvel Comics continuity
Generation 1
After Scorponok's Decepticons arrived on Nebulos and set up a headquarters in a former industrial complex on the remote plains of Thok, Monzo was kidnapped by Mindwipe, Weirdwolf, and Skullcruncher to subject to their experiments. Monzo's capability to experience fear was removed via Mindwipe's hypnosis, and the former professional wrestler was encased in a bubble created by the Decepticons' experimental polymer membrane machine. With a blast from Skullcruncher's anti-gravity gun, Monzo began floating upwards, towards the open skylight. When it became apparent to the Decepticons that the bubble was going to pop, indicating a structural disorder in the polymer membrane bubble, Mindwipe flew after Monzo. No sense wasting a good laboratory animal, after all.
Lord Zarak, another prisoner of the Decepticons, made a deal with them to become their Headmaster partners in order to equal the Autobots' own new Headmaster might. Monzo was next seen as the Headmaster partner of Weirdwolf. Whether he was still hypnotized at the time of this conversion or if he joined the Decepticons of his own free will is not detailed. Love and Steel!
Generation 2
Weirdwolf served in the Decepticon army, and so presumably Monzo did also.
Classics
In the fifteen years after the battle on Klo, Weirdwolf fell under the sway of the mysterious Bug Bite, who had Weirdwolf rebuilt to remove his Headmaster technology, resulting in both a spurned Monzo and Weirdwolf being even less coherent than he was previously. Weirdwolf's recreation was Bug Bite's downfall; Monzo turned to the Autobots with what information he knew, and a rogue Autobot team led by Ultra Magnus arrived and put a stop to Bug Bite's insurrection.
