Bumblebee

Few crossover events dare to mash up Marvel's mightiest heroes with Cybertron's legendary warriors, but that's exactly the wild territory Bumblebee stakes out in the 2007 Modern Age gem New Avengers / Transformers. Debuting in the very first issue of this Stuart Moore and Tyler Kirkham collaboration, Bumblebee shares the page with an extraordinary roster — Captain America, Optimus Prime, Wheeljack, Ratchet, and Runamuck — making for one of the more delightfully unexpected assemblies in comics history. With only four catalog appearances, this is a rare, focused slice of crossover comics that rewards the curious collector willing to dig into Marvel's adventurous publishing experiments of the era.
