Rayvis

Rayvis was a male Gen'Dai warrior who served as the leader of the Bedlam Raiders, a marauder group based on Koboh. A powerful warrior who had slain many Jedi during the High Republic Era, Rayvis served as an enforcer and servant of the renowned Jedi Knight Dagan Gera after Gera bested him in single combat. His loyalties remained strong even after Gera was placed in stasis for two centuries, and—after breaking free of imprisonment of his own—he rescued his old friend in 9 BBY, restarting Gera's quest to return to the planet Tanalorr.

Rayvis was subsequently confronted and defeated by the Jedi Knight Cal Kestis, who granted Rayvis the honorable warrior's death the Jedi before him had refused to do, after yielding to him after their bout.
