Luperus, sometimes known as Cerbekus, is more of a monster than a villain: something to haunt your nightmares, especially if you're a Chia. Many Chia parents tell their children Luperus will come and get them if they misbehave.
Luperus lurks in a cave which joins the Haunted Woods with Altador. Though many run from him, in fact he just wants to play fetch with visitors.
This character is based on the three-headed dog Cerberus from Greek mythology.
During the Void Within plot, Luperus was infected by the Void in his left head. The conclusion of the plot claimed he had been cured, but other characters infected by the Void still retained their infection so it is unclear if it was removed or merely halted with the collar device seen below.
