Marvin Mobuto

"I didn't know you, Sarge, but I sure as hell wish I had. You must have been one hard-core son of a bitch."

— SPARTAN-117, upon finding Mobuto's body

Staff Sergeant Marvin Mobuto was a tough-as-nails marine and the first Reclaimer during the Flood infestation on Halo.

Biography

Staff Sergeant Mobuto participated in the Battle of Reach, and was on the Pillar of Autumn when it made a blind jump to escape from Reach. Since the Pillar of Autumn traveled directly from Reach to Halo, it can be assumed Mobuto was involved in the battle itself. However, his involvement during the conflict is unclear and unaccounted for. He participated in the defense of the Autumn and was jettisoned before the craft crashed into the ringworld, Halo.

A Reclaimer

While on the ring, Mobuto was contacted by 343 Guilty Spark, who used Halo's teleportation grid to transport him to the Library, much like he did with the Master Chief. Instructed to retrieve the Index, Mobuto fought valiantly through hordes of Flood Combat, Carrier and Infection Forms. With little experience against the enemy and standard, UNSC-issued body armor as protection, Mobuto eventually succumbed to the Flood's might. His body was completely thrashed and mangled to the point where the Flood Infection Forms could not make use of his body.

Master Chief John-117 found Mobuto's body in the Library during his mission to collect the Index. John discovered Mobuto's identity through his dog tag, and paid his respects to the Marine. Mobuto's determination inspired the Spartan to continue through the Flood-infested halls and complete his mission.
