Marc Kumar was a freelancer P.R. and marketing expert who met Pepper Potts in Las Vegas, during Tony Stark's absence in space, while he was handling a drunk client at a party Pepper was attending. After dating for months, Marc proposed to Pepper in Scotland. From the stories Pepper told him about Stark, Marc came to the conclusion that he treated her badly, and grew resentful at Tony.
Shortly after that, Marc was given the Liar ring of the Mandarin due the secret hate he harbored towards Stark. He joined other Mandarins in fighting Malekith the Accursed after the Dark Elf began to steal the rings from other bearers. He kept working with the remaining Mandarins in Mole Man's plan to create ring-powered weapons to destroy cities from their base in Sinister London. When Iron Man, the Trojan Guard, Abigail Burns and Iron Patriot pinned them down, Marc revealed his identity as the Liar to Tony, and attempted to escape, creating an illusion of Pepper Potts to use as collateral. Having seen through Marc's illusion, Iron Man called his bluff and grazed Marc with a repulsor blast that went through the phantasmal Pepper.
Marc's ring was taken from him, and he was hospitalized in a high-security S.H.I.E.L.D. hospital. Pepper later visited him to return her engagement ring to him, claiming that she didn't need saving, and that even though Tony had treated her bad, at most times he didn't.
