Bael Nomine

Memory Beta, the wiki for licensed Star Trek content.

Bael Nomine was a male Betazoid cadet at Starfleet Academy in the 2370s. He was an expert in holography, and was able to adapt and perfect the holographic technology seized by Starfleet from Ardra, allowing him to change his appearance at will.

He was recruited into Red Squad, and assigned by Admiral James Leyton to Starbase 375, under Commander Ishmael Snowden. There, he was ordered to set off a bomb, made to look like the work of the Dominion, in order to bolster Leyton's call for increased security measures. However, when he was ordered to set off a second bomb, certain to cause a large number of casualties, he balked, and turned against Leyton and Snowden. He was then taken into custody and returned to Earth to face a court martial. (TNG eBook: Slings and Arrows: The Oppressor's Wrong)
