Wyatt
From FEInfobase
Little is known about Wyatt, not even his real name. that is something he plays close to his heart, just like the reason he was drummed out of Starfleet.
As he joined the crew of the Starlight it became apparent that Wyatt has a prosthetic hand, this came to light when he was attacked by Aegis another member of Starlights crew. During their altercation the Caitian ripped one of Wyatt's digits off. This made Wyatt declare his intent to kill the creature if it ever came close to him again.
Wyatt has a thing for older weapons, on Scardia he has built himself quite an armoury of guns and rifles ranging back to old flint lock models and stretching as far forward as early Starfleet Plasma weapons. Wyatt's personal side arm is a vastly modified plasma based weapon.
