Henry (Sangheili)

"Henry" was a Sangheili prisoner of war aboard the human prison ship, The Mona Lisa. How he and his compatriots were captured by the UNSC remains unknown, but it is presumed they were found at the derelict ruins of Installation 04 and placed on the prison ship.

The Mona Lisa
After being captured by the UNSC, he and an unknown amount of his compatriots were brought on board for study. One of particular interest, however, was infected by an unknown parasite. ONI officer John Smith was brought aboard to study the infection, starting by infecting other Sangheili, then prisoners. At an unknown point in time, the Flood broke out from capture, running rampant. Somehow, he and a human prison named Rimmer survived the horrors of the outbreak to hole up in a maintenance room. Rimmer called him Henry, due to the lack of the ability to communicate names.

Days later, they were found by Benti, Gersten and Clarence, surviving members of Lopez' squad, which had decided to investigate after a survivor had found his way to an escape pod and was found by The Red Horse. After fighting their way through the infection, Benti, Rimmer and Henry formed somewhat of a bond, working together with enough efficiency to regroup with MacCraw and Lopez, the other survivors of the squad. Henry earned enough trust from Benti to be given the Assault Rifle originally assigned to Rimmer.

Upon reaching the pods, Clarence revealed his status as a Section III operative, eliminating Rimmer, much to the grief and rage of Henry. Benti, being previously injured, forces Clarence into the Flood beyond them, sacrificing both their lives. Henry and Lopez make the rest of the way to the pod, finding that there was room only for one. Lopez was out of ammo and couldn't finish off the Elite, and Henry still had his cricket bat. With thirty seconds left, they fought for the pod, their fates are unknown.
