Bacillus

A menacing presence born from the early 1990s Marvel universe, Bacillus made their debut in Marvel Comics Presents #114 in 1992, brought to life by the creative pairing of Ann Nocenti and Steve Lightle. That anthology series was a proving ground for some of Marvel's most intriguing corners, and Bacillus emerged into some genuinely charged company — sharing pages with the likes of Ghost Rider, Logan, and Giant-Man. Rare and elusive with only a handful of catalog appearances, this is exactly the kind of Copper/Modern Age obscurity that makes digging through back-issue bins so rewarding.
