Decay

Decay made their Marvel Comics entrance in 1999's Juggernaut #1, brought to life by writer Joe Casey and artist Terry Shoemaker at the dawn of the modern era. Over a surprisingly long publishing footprint stretching to 2016, this character carved out a niche in the Marvel Universe, most notably turning up in the pages of Avengers and Avengers Assemble — rarefied company that speaks to their place among Marvel's bigger-stakes storytelling. Sharing adventures with the likes of Conquest, Stonecutter, and Yoshiro Hachiman, Decay occupies that intriguing corner of the Marvel cosmos where deep-cut characters reward the curious collector willing to dig past the household names. Even an entry in the All-New Official Handbook of the Marvel Universe A to Z confirms this is a character Marvel considered worth cataloguing — a small but satisfying badge of legitimacy for any completist hunting the full picture.
