McKaskill

McKaskill is an ONI agent who served as a mechanic and undercover for Colonel Herzog on the UNSC Apocalypso before its destruction in 2552.

Early Life
His family came from Durban, a city on Biko. They fled the Outer Colonies before Biko was glassed, leaving McKaskill to be raised in refugee apartments.

Apocalypso
He served on the ONI spyship Apocalypso long enough for Melissa, the ship's AI, to become protective of him. When the ship picked up the Deep-Space Artifact, McKaskill tried to send a message to Herzog about it. Melissa, however, recognized the act as treason and halted it at once to keep her crew member safe from capital punishment.

After the ship crashed in Lunar orbit and Major Standish acquired the artifact, Standish attempted to eliminate every former crew member including McKaskill. The brakes of his Hog were cut, but he was able to survive. He went dark after that, taking James James' black taxi across the country.
