Runamuck

Runamuck crashes into comics history as part of one of the Modern Age's most unexpected crossovers — the 2007 Marvel event New Avengers / Transformers, where the worlds of Earth's mightiest heroes and Cybertron's mechanical warriors collided on the same page. Debuting in that landmark first issue courtesy of Stuart Moore and Tyler Kirkham, this Transformer shares the stage with heavy hitters like Optimus Prime, Bumblebee, and Captain America — genuinely rarefied company for any character. With only a handful of catalog appearances, Runamuck is a true curiosity for the dedicated crossover collector, a snapshot of a gloriously ambitious moment when Marvel swung for the fences and brought two beloved universes together.
