Private E. Hamboyan was a MACO assigned to Enterprise NX-01 during the search for the Xindi weapon in 2153.
In November of 2153, Hamboyan was one of the MACO escorting Captain Archer and a few Triannons in Shuttlepod 1 to the surface of the planet Triannon. (ENT: "Chosen Realm")
Hamboyan stood guard in the shuttlebay where an alien transport pod was opened. Later, he stood guard in sickbay after the crew recaptured the Sphere-Builder that had just wrought havoc on the ship. (ENT: "Harbinger")
Hamboyan was among the MACOs to volunteer to board the Xindi weapon. He was, however, not chosen by Reed, and remained on board Enterprise, where he assisted in repelling the invading Sphere-Builders. (ENT: "Countdown", "Zero Hour")
In 2154 he served as a guard for Arik Soong when he visited the sickbay and was later beamed down to Verex III. He also guarded Archer along Lieutenant Reed when the captain discussed with Malik in his briefing room. He was unable to stop Malik when he took Archer as a hostage. (ENT: "Borderland")
In the holodeck recreation of Commander William T. Riker, Hamboyan accompanied Shran, Captain Archer, T'Pol, Commander Tucker, and Lieutenant Reed to the negotiations with the alien criminals, who had captured Shran's daughter Talla. (ENT: "These Are the Voyages...")
