Runamuck

Runamuck is a Decepticon warrior who debuted in Marvel's original Transformers series. A loyal soldier on the side of Megatron's faction, he is a Battlecharger — a class of Decepticons that transform into cars and are known for reckless, destructive behavior carried out purely for personal enjoyment.

Bursting onto the scene in 1986 courtesy of Bob Budiansky and Don Perlin, Runamuck is a Copper Age Decepticon who made his mark in Marvel's landmark The Transformers series — sharing those explosive pages with heavy hitters like Optimus Prime, Soundwave, Starscream, Shockwave, and Galvatron. Though his catalog footprint is modest, he's earned a place in reference staples like The Transformers Universe and the Transformers Compendium, cementing him as a genuine piece of the original Marvel mythology. For collectors who love the deep cuts of that foundational era, Runamuck is exactly the kind of character who rewards digging in.
