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 Marine and most likely 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

Mobuto was one of the ODST's who went with Captain Keyes "weapon". However, after the rest of the group perished due to Flood (except Johnson), he must of escaped. Then, 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 Forms, Carrier Forms 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. It is suggested he could be a SPARTAN I due the great battle he must have fought against countless Flood numbers.

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. Master Chief was surprised at how far Mobuto had managed to come as he himself had been pushed to the limit to get as far as he had even with his augmentations and MJOLNIR body armour. Mobuto's determination inspired the Spartan to continue through the Flood-infested halls and complete his mission.
