Jimmy Cage is the alleged brother of Johnny Cage, appearing only in the webseries Mortal Kombat: Federation of Martial Arts. He is said to bare a "striking resemblance" to the actor, but hides a "deadly secret".
Jimmy's only fight in FoMA is against Kitana. He begins the fight by looking her over and dismissing her, but she kicks him hard enough to knock his $650 sunglasses off. As Jimmy goes to pick them up, he is knocked down by Kitana, and she then stomps on the glasses, breaking them. He gets a few good hits in on the princess, but is ultimately beaten easily.
