Fred is a formalin-preserved rabbit specimen revived by Kunstlijk using a special invention. Upon awakening, Fred, Michael, and Sonny exhibit gangster-like behavior, immediately asserting independence from their creator. The trio operates with a mafia mentality, marked by fierce internal loyalty and violent tendencies towards perceived enemies. Their interactions involve deal-making when advantageous, underscored by a stereotypically Italian leitmotif reinforcing their criminal archetype.

Their primary motivation shifts dramatically when Sonny vanishes due to malfunctioning time-travel technology created by Kunstlijk. This event triggers an intense pursuit by Fred and Michael, who relentlessly hunt Kunstlijk to retrieve Sonny or exact vengeance for his disappearance. During this pursuit, they acquire firearms, escalating their vendetta's threat level.

Fred functions primarily within the collective dynamic of the rabbit gangsters.
