- "Mancini, thank you. You will be receiving your payment shortly."
- ―Ian Quinn
Carlo Mancini was an ex-Special Forces mercenary employed by Cybertek to provide security, and to safeguard the transportation of merchandise across Italy.
During an operation by S.H.I.E.L.D. to track and apprehend Ian Quinn, Agent Coulson's team marked Mancini as the leader of the security detail protecting a product to be delivered to Quinn. Unbeknownst to Coulson, Mancini and his team were tipped off to S.H.I.E.L.D.'s plan by Luca Russo, a corrupt Italian law enforcement agent who was being payed off by Cybertek to protect their interests in Italy. Mancini and his team successfully drove Agent's Coulson, May and Ward from the train. However, they were unaware that Skye and Agent Fitz were still aboard and followed them to Quinn's villa.
Mancini delivered the package to Quinn and disarmed Skye, who had infiltrated the villa and discovered Mike Peterson in a hyperbaric chamber. On Quinn's orders, Mancini affixed the device, a cybernetic leg, to Peterson's amputated right leg. A short time later, while waiting for his payment, Mancini and his entire team were met by Peterson, then codenamed "Deathlok", who single-handedly (and without breaking a sweat) eliminated them all - permanently.
