Zookeeper (Samuel Register) is a character appearing in DC Comics, primarily as an enemy of the Teen Titans.

Zookeeper first appeared in Teen Titans #13-15 (Sep. - Nov. 2004) and was created by Geoff Johns and Tom Grummett.

Samuel Register is an assistant of Mark and Marie Logan in Africa. He despises their rambunctious son Garfield, who constantly causes damage in his lab.^[1]

After the Logans are killed in a boating accident, Register attempts to continue their work. He conducts inhuman experiments on animals, earning the nickname "Zookeeper".^[2]

In the "Beast Boys and Girls" storyline, Register steals a sample of the Sakutia virus, infecting himself and thousands of children and gaining shapeshifting abilities. However, Beast Boy subdues Register by transforming into a Sydney funnel-web spider, after which he is imprisoned in Alcatraz and his blood is used to cure the children.^[2][3]

Zookeeper later joins Alexander Luthor Jr.'s Secret Society of Super Villains and Superboy-Prime's Legion of Doom.^[4][5]

Zookeeper can turn into any animal at will, similar to Beast Boy.
