Dark Kury Virus Kury Orochi Kury Evil Kury And several other nicknames that Kury received when he showed his dark side on one role play in THERE ARE MORE NAMES, PLEASE TELL ME IF YOU REMEMBER XD
His berserk mode was made to just activate in very stressful situations, so he can become more active, strong, and protect the others in the surroudings. After this, as a side effect, he becomes a total jerk, and behaves in inapropriate and scary ways. But somehow his CPU got a virus and he started to show it for no reason (and also for fun).
