Darth Warlock

This is an OC and base
If you remove the armor, it can be used as a base I think.

Story: saber to throat, Jedi knight Warlock had lost against a sith only known as “the shrouded one.” His fate was nearly sealed when he recalled a forbidden ability he had reviewed without the counsel’s consent. As the saber struck him, he drew an immense amount of power through the dark side of the force, allowing him to withstand the blade and repel his opponent. Unfortunately as an effect, the dark side of the force corrupted him and took partial possession over him. This shifted his mindset, and actions to pursue his “rightful” place in the ranks of evil.
