Watchman

Watchman, aka Lieutenant Dahmer is an A Class Atlas-Type who manifested his powers during US Army basic training.

He served in both the China War and the Caliphate War, and after his final tour (where he met Astra, both as a recruiter and later at Whittier Base) he was recruited by the Sentinels to help fill in the holes in their roster and to further train Astra.
