Zookeeper

Emerging from the chaos of DC's landmark Infinite Crisis event, Zookeeper made their debut in 2006's Villains United: Infinite Crisis Special #1, brought to life by the celebrated creative team of Gail Simone and Dale Eaglesham — a pedigree that signals real menace from the very first page. This Modern Age figure has proven surprisingly durable, with a presence stretching nearly two decades and appearances alongside heavy-hitters like Green Lantern, Firestorm, The Flash, and Beast Boy. Most at home in the pages of Titans and Teen Titans, Zookeeper is the kind of deep-cut DC villain that rewards the dedicated reader — a figure born in one of comics' most turbulent crossover events and still lurking in the shadows of the DC Universe today.
