Carl, the former lover of Marty Chonks' wife, is angry over her death and is looking for revenge. Agreeing to meet Marty at the Bitch'n' Dog Food Factory, he successfully avoids Marty's trap by killing him with a concealed shotgun, effectively taking over Marty's business. Carl can be killed by Claude as he walks away from Marty's corpse. However, the Love Media website suggests that the conglomerate owns the Bitchin' Dog Food Factory.
Although he is referred as "Carl" by Marty in a mission cutscene, the real name of this character is "Carlos", it is revealed in the PC version of the game if you fail the mission: walking away with the car when Carl goes to enter into the car. The mission fails with the following inscription: "You have left Carlos the loan shark behind!"
