Bisenti

Private Bisenti was a UNSC Marine, voiced by Mike Madeoy, who was assigned to the UNSC Pillar of Autumn.

During The Battle of Reach, he was one of the Marines aboard Reach Station Gamma, above Reach. He, along with Staff Sergeant Avery J. Johnson, Private First Class Wallace A. Jenkins, and Private O'Brien, were fighting a group of Jackals when Spartan-117 and Spartan-058 boarded the station to destroy the logs of the ONI Prowler Circumference. He was picked up with Johnson and the Chief when they took a Pelican and flew back to the Pillar of Autumn.

He later landed in the same Bumblebee lifepod as Sergeant Johnson on Alpha Halo, and they met up with the Master Chief again. He was one of the first to see him. Bisenti then returned to Alpha Base with his squad and they later traveled to what they thought was a Covenant weapons cache, which was uncovered by a captured Elite named 'Qualomee. It turned out that the cache was actually one of the Flood Containment Facilities. Bisenti and the squad were soon attacked by Flood Infection Forms. Bisenti escaped from the Flood Containment Facilities and was evacuated by Echo 419 after The Chief found what was left of the squad on his way to the surface. He was presumed killed when John-117 destroyed the Pillar of Autumn's fusion engine core, causing a wild-cat destabilization, in which destroyed Alpha Halo.
