A Besalisk Jedi Master and Jedi General during the Clone Wars, Pong Krell was the owner and wielder of two lightsabers. These weapons were both double-bladed, with one emitting a blue blade and the other a green one. For convenience in carrying, they could be folded in the middle.
Pong Krell's pair of identical lightsabers were built primarily from metal and were larger than typical lightsabers to accommodate the size of their owner's hands and body. Each lightsaber had a blade on either side of the hilt, making them double-bladed, a design not commonly used by members of the Jedi Order. When activated, one lightsaber produced two blue blades and the other produced two green blades. Upon activation, both lightsabers created a distinctive low-pitched hum, different from the sound of a standard lightsaber. A hinge located at the midpoint of each lightsaber allowed Krell to fold them in half for easier carrying, even though they could still be activated while folded. The lightsabers were powered by internal Kyber crystals. When not in use, Krell usually clipped his sabers to his utility belt around his waist.
During his time on Umbara, Krell rarely used his lightsabers and did not fight alongside his troopers, unlike most Jedi. He used them once to eliminate several banshees that were attacking his troops and again (while folded) to threaten CT-5555 into silence.
When Krell was revealed to be a traitor, he used his lightsabers to murder numerous clones as they tried to apprehend him, although he sometimes abandoned them to kill a few troopers with his bare hands. Afterward, Krell was lured into the grasp of a dangerous vixus, a plant-like creature native to Umbara, that attempted to devour him. As the creature reached for him, Krell managed to sever its tongue, causing it to slam him into the ground and making him drop his green lightsaber. Despite this, Krell defended himself from the clones with his remaining blue lightsaber and freed himself from the vixus' grasp, only to be stunned by Tup and taken into custody.
The lightsabers of Pong Krell made their debut in "Darkness on Umbara," which was the seventh episode of Season Four of the animated television show Star Wars: The Clone Wars. The episode originally aired on October 28, 2011. Designed by concept artist Chris Glenn, Krell's lightsabers were the first instance of hinged double-bladed lightsabers to appear in Star Wars.
