Peng was a leader of the Chinatown Crew who made a deal with Eli Morrow to assist him in building a weapon against S.H.I.E.L.D. in exchange for payment. However when Peng refused to help Morrow any longer, he killed him by using his powers to put diamonds into Peng's lungs.
Working for Eli Morrow
Betrayal and Death
- "You're right, hard days work deserves a hard days pay. Hope you take diamonds, they're unrefined but they're priceless once properly cut. Speaking of which, you may have to cut the rest out of his lungs."
- ―Eli Morrow
Morrow responded by demonstrating his new powers by lodging diamonds inside Peng's throat, killing him. Morrow ordered his men to cut his lungs if they wanted any for their payment. This terrified the other members of the Chinatown Crew into working without question while Morrow then continued constructing his Quantum Battery, saying that he'll show S.H.I.E.L.D. what he was making.
