Fictional character biography
Dr. Samuel Register worked with Mark and Marie Logan in Africa. He despised their rambunctious son Garfield who constantly caused damage in his lab. He was (and still is) obsessed with people calling him "Dr. Register" and nothing else.
After Logan's parents successfully cured Garfield of Sakutia, Register went on to try to finish their work. He became mad for results and inhumanly slaughtered animals in experiments which produced grotesque mutations. This earned him the nickname "Zookeeper".
In the "Beast Boys and Girls" storyline, Register stole a sample of Sakutia to try to mutate it like Garfield's parents did. He accidentally infected himself and every kid in San Francisco. When Beast Boy was infected, the virus in him was canceled out and he was cured.
Zookeeper injected venom from the Sydney funnel-web spider into Garfield and attempted to dissect and extract the cure to Sakutia from him. Cyborg and the other Titans kept Register busy while Raven healed Beast Boy. Wanting to stop Zookeeper desperately, Garfield reinfected himself with Sakutia. His powers back to speed, Beast Boy fought and defeated Zookeeper. He also found a way to cure the kids that were infected. Apparently, Register is immune to Sakutia like Beast Boy.
Powers and abilities
Zookeeper can turn into any animal at will, just like Beast Boy. However, his side effects are different from Garfield's. His skin is purple and scaly, and his eyes and hair did not change color with his skin.
