Der Rudi is a highly intelligent, optimistic action hero who prefers non-violent conflict resolution wherever possible. His main weapon is his practical application of scientific knowledge and inventive use of common items; constructing contraptions within minutes using nothing more than his ever-present Swiss Army knife, a paperclip, and duct tape. Even in cases where his improvised devices are used to attack hostile opponents, he is always doing so in self-defense and, if possible, subduing or disabling rather than killing.
