Dundun Qwerty is a Tech District CRiTORA and the leader of the CRiViRUS Gang.


The Error Message CRiTORA. Dundun Qwerty is the leader of the CRiVIRUS Gang, a group of troublemakers helping the evil Queen ViRUS. Dundun likes to mock other CRiTORA with sarcastic computer error messages, but he's also a skilled fighter, so most CRiTORA don't even try to mess with him. One punch from him can cause a CRiTORA to have a BSOD moment. Why he sides with the ViRUSES remains a big mystery...
