Pong Krell

 Pong Krell was a male Besalisk Jedi Master who served as a Jedi General in the Grand Army of the Republic during the Clone Wars. A powerful Jedi and a recognized war hero, he was relentless in his tactics on the battlefield, seeking success at all costs. As a combatant, he was an especially ferocious lightsaber duelist; the advantage of four arms allowed him to wield two double-bladed lightsabers at the same time. As a general, Krell found insubordination intolerable and required strict adherence to command from all of his soldiers. During the war, Krell foresaw how the Republic would be destroyed from within, thus paving the way for the rise of a New Order. This vision, coupled with his lust for power, ultimately caused Krell to abandon the Jedi way. Outwardly, he maintained the appearance of his ties to the Jedi and Republic. In secret, Pong Krell had embraced the dark side of the Force.

Around 21 BBY, when the shadow planet Umbara seceded from the Republic, Pong Krell was given command over the 501st Legion, serving as an interim general during Anakin Skywalker's absence. Krell deliberately crafted incompetent battle strategies in order to sabotage the Republic's campaign to retake the planet. By covertly assisting the Separatists' efforts to retain Umbara, Krell hoped to join the Sith ranks as a disciple of the Sith Lord Darth Tyranus, thus securing a place for himself in the future Empire.

Krell's plans were ultimately thwarted by the clone troopers under his own command. When his duplicity was uncovered, Krell was confronted by Captain CT-7567 (nicknamed "Rex") and troopers from the 501st Legion and the 212th Attack Battalion. Although he single-handedly slaughtered scores of clones, eventually he was captured and detained. While restrained by binder cuffs, Krell was fatally shot in the back by Dogma, his most loyal soldier, thus ending the fallen Jedi's life.
