Yuika

Yuika is a character from the MegaMan Battle Network series. She appears in MegaMan Battle Network 6 and MegaMan Beast. Her NetNavi is CircusMan.EXE

MegaMan Battle Network 6 Yuika is a member of the WWW. She first appears in Central Town advertising a dance festival at Central Area 3. Once there, she uses CircusMan.EXE to drain the energy out of the NetNavis there. She catches one Cybeast and runs after the Netpolice arrive. Yuika takes part in a successful mission to capture MegaMan.EXE, after which she, Vic, and Ito break away from the WWW and form their own group; however, during the split, they lose MegaMan.EXE and have to retreat. They show up again to kidnap Iris.EXE and are sucessful. Once they have Iris, Baryl tries to rescue her, but the ex-WWW members beat him up and nearly kill him before Joe Mach shows up and drives them away. Yuika and the others appear again during the final battle against Lan. Their NetNavis are deleted, but they are about to attack Lan themselves when Chaud, Mayl, Dex, Yai, Mick, and Tab show up. Yuika, Ito, and Vic jump off the pavilion and are knocked unconscious. They are later arrested for their crimes.

MegaMan NT Warrior
She appears in Rockman EXE Beast and Beast +. She and Blackbeard live in Beyondard and work for the Beyondard Lord Wily. Following the ending of Beast+, she and Captain Kurohige are mysteriously transported to what they consider to be Beyondard (note, characters on both sides consider the other parallel world Beyondard). After attempting to cause chaos in the world of not their own, they meet the Dr. Wily of Beyondard (yet again, not the one they are used to). When Dr. Wily refuses to aid their cause of revenge against Netto and Rockman, they steal some chips which they believe to be synchro chips (in fact, they are reverse synchro chips), by burying Dr. Wily and Dark Miyabi with a pile of cans while the two were sharing a drink. They use the reverse synchro chips to cross fuse and end up in Internet City. They are saved by the work of Rockman, Shadowman and Dr. Wily. Afterwards, she and Captain Kurohige are sentenced to work at an aquarium by Dr. Wily.
