Bio: Agent Morelli was a member of S.H.I.E.L.D. and was aboard the Helicarrier that illegally brought She-Hulk on board to determine if she posed a possible threat to humanity similarly to how her cousin The Hulk did at certain points in his life.
When a civilian that was actually just a host for a collective hive mind of human level intelligence cockroaches was transported on board at the same time as She-Hulk, they crashed the S.H.I.E.L.D. Helicarrier to show the world how powerful they were. She-Hulk was able destroy every single one of the cockroaches however. Morelli was one of the agents killed when he went to try and get the port rotors up and running again to prevent the Helicarrier from crashing. The handle had been booby-trapped and exploded, killing himself and an Agent Mackie in the process.
