Euclid
Euclid is a young scientist and the inventor of the Ultimate Pet Zapper (Pet Zapper V2). He conducts his experiments in The Darkside.
The Zapper
Euclid has allowed the public to use his zapper in exchange for 15 wizard tokens, though he warns the device is still in a testing phase and the results may be unpredictable. For 400,000sP, he can zap a player's pet into a random Experiment.
On February 10, 2015, Euclid gained his current appearance thanks to his rejuvenation experiment. The energy generated by that experiment also wiped out the original Pet Zapper, leaving Euclid's zapper the only one remaining in Darkside.
During Morostide, Euclid lets users zap themselves to randomly unlock one of many unique Zapper Skins in exchange for 50 wizard tokens.
Rivalry with Ian Asmodeus
Despite having studied alongside Ian Asmodeus, the two scientists do not get along. Asmodeus once accidentally turned Euclid into a Wyllop for five years.
Euclid's pet Cringing Constrictor was a "gift" from Ian during his time as a Wyllop — Ian made the minion to tease his rival, but Euclid bonded with it and kept it after regaining human form.
