Blackstone

One of the Sentinels' founders and a mentor to Atlas, and later to Astra, Blackstone was a retired US Marine turned stage magician. His power is essentially "stage magic" - he can appear and vanish both himself and objects he pulls from his hat or waves away (teleportation), fly (levitation or flight), and spin completely convincing visual illusions.

He has always been the team's intelligence analyst, and after the deaths of Atlas and Ajax, the last founding members, he became the team's de-facto leader.
