The primary focus of his jobs are mostly related to attacks against rival gangs, with one of these mission requiring that Claude turn his back against the Diablos by killing several of its members. The final "job" involved Claude being lured into a trap, where Catalina has dispatched vans of "SPANK-ed up madmen" suicide bombers to kill Claude, an act that subsequently fermented relationships between Claude and the Yardies. He is never seen in person in Grand Theft Auto III, but does during his appearances in Grand Theft Auto Advance. In Grand Theft Auto Advance, he appears as Mike's fourth boss.
