I guess my new Padawan is arriving."
"There's two?
—Obi Wan and Anakin await Devin and Ahsoka's arrival
Devin Kallish was a Male Human Jedi Padawan and was the second Padawan of Obi-Wan Kenobi. Kallish was known for wearing a beanie on many occasions. After the Skirmish on Rishi, Devin often would serve in battles with Echo and Fives.
Arrival on Christophis[]
When Ahsoka and Devin both got on the shuttle transporting them to Christophis, Devin introduced himself to Ahsoka as they talked. Devin told Ahsoka a little bit about himself but before he could finish his story, he realized that they were touching down. As the two got out of the shuttle, much to Skywalker's surprise, there were two Jedi Padawans. Anakin asked Obi-Wan if he was taking on two Padawans but to Anakin's surprise again, he was not. Anakin asked Devin and Ahsoka what was going on and Devin answered by saying he was Obi-Wan's Padawan and that Ahsoka was Anakin's Padawan. An unhappy Skywalker groaned and took Ahsoka with him Obi-Wan though introduced himself to Devin and told him they were looking for Whorm Loathsom. As the two made their way across the city, much to Kallish's surprise, Kenobi did not attack Loathsom, surrendering instead. Devin quickly realized what was going on and decided to play along. After many hours of stalling, Loathsom realized the situation and attacked Kenobi, but Obi-Wan used Loathsom as a shield and Devin attacked the battle droids protecting him. The battle ended quickly and Obi-Wan started to take a liking to his new Padawan.
Stranded on Rishi[]
Later in that year, Devin Kallish was sent to Rishi with Jedi Knight Nahdar Vebb, Captain Rex and Commander Cody. As they arrived, they were greeted by a commando droid disguised as a clone trooper. However, Nahdar and Devin were not fooled and Nahdar plunged a lightsaber through the droid. As they attempted to enter the base, they were denied by the guard. The four later saw a flare go up into the air; Nahdar, Cody, Rex and Devin found three living clones who introduced themselves as Echo, Hevy, and Fives. Devin came up with a plan to have Rex pick up a droid head and use it as a disguise. Rex, Fives and Echo all agreed to the plan, but Hevy, Cody and Nahdar were not convinced the plan would work. When the plan was done, it actually worked and the seven made quick work into the base, but the only way to survive would to destroy the base. Hevy hooked all the wires up and readied the bomb, but it would have to be activated manually. Nahdar and Devin both offered to sacrifice their life, but as the droids approached, Hevy told them to escape through the air vents. As Hevy held off the droids, the six made their escape and were able to flee to see the destruction of the base. Devin later told Ahsoka and Obi-Wan what happened on Rishi. Nahdar Vebb would die two weeks later and his death would put Devin in sorrow.
Battle of Orto[]
In 21 BBY, Devin Kallish was knighted and was sent to the Ortolan homeworld of Orto along with Obi-Wan Kenobi, Ahsoka, and Anakin to free Ortolans from the clutches of the Bothan Separatist leader Rol Heklin. As Devin arrived with Rex into Heklin's compound, they fought against Heklin's forces. A droid commando fired a rocket at Rex but Devin hurtled the rocket back at the droid. However, Devin's force was not accurate and the rocket hit the generator.
Kallish quickly sealed off the doors to make sure the Ortolans would not die in the explosion, but Rex and Devin were both trapped under the rubble and Obi-Wan sensed his apprentice was losing health fast. Kenobi quickly rushed toward the base and sifted through the rubble, looking for Devin, but found Rex first. Kenobi kept looking through the rubble and finally found Kallish, but Devin Kallish collapsed to the ground and was brought to the medical base. Devin awoke and found himself hooked up to a life support machine. He took a look around and saw an Ortolan Jedi. Devin asked Obi-Wan who the Ortolan. Jedi was and Kenobi responded by stating that his name was Nelek Jalas and that he was to be Devin's first Padawan. Kallish responded stating he would be honored to train Nelek, but Devin stated that, since he needed medical attention, Nelek should join Obi-Wan in the battle.
Nelek did not agree with Devin at first but decided to follow Master Kenobi. As the two made their way into the battle, Nelek disabled two Armored Assault Tanks using the Force and threw them into droid reinforcements. Then, he charged at the Separatist forces but Nelek found himself surrounded by a group of Sith: a Bothan, a Duros and a Kel Dor. Nelek tried to fight them off but was in danger. Devin sensed this and left his medical attention to go aid Nelek. As Devin arrived. Nelek had already killed the Duros Sith but was still threatened. Devin lashed at the Bothan Sith and decapitated him; then, Devin impaled the Kel Dor Sith with a lightsaber and used the Force to heal Nelek. After the battle, Devin told Nelek that he might make a great apprentice.
Trapped to Wasskah[]
After the Battle of Felucia Devin and Ahsoka were trapped on Wasskah and were hunted by Trandoshans, Devin and Ahsoka quickly met up with a group of Padawans Kalifa, Jinx, and O-Mer as the 5 decided it was time to fight they were ambushed by Trandoshan Hunters deep in the Jungle of Wasskah as Ahsoka, Kalifa, and Devin went deeper into the Jungle they witnessed a Terrelian-Jango Jumper Jedi and a Snivvian Jedi fall prey to the Hunters, as Ahsoka was about to move into action she was quickly stooped by Devin and Kalifa, the 3 made their way away from the other hunters but as they got to a tree they realized Kalifa had been shot, Ahsoka and Devin attempted to heal her but out of no where a second shot was fired by Garnac at his anger of his son Dar's death. Devin and Ahsoka witnessed Kalifa's death at the hands of Garnac they both left the body of Kalifa at the stump of the tree while Garnac's cries still echoed of "You killed my son!". Ahsoka and Devin met up with Jinx and O-Merr and told them of Kalifa's death and this deeply saddened the Jedi Padawans, Jinx told them he thought they should stay there however Ahsoka and Devin believed they could attack the ship and destroy the Hunters as the 4 rushed into action they attacked the ship and were quickly attacked by the hunters however O-Mer attempted to kill one of the hunters but was thrown off the ship but was caught in mid-air by Jinx, O-Mer thanked Jinx but had trouble holding his hand. Jinx pulled his arm up onto the ship and brought O-Mer up with him, Devin attacked one of the hunters and snapped his neck, Ahsoka jumped into the Ship along with Devin and Jinx and the 3 were able to destroy the ship and as they made their way onto the land, Ahsoka believed they might die so Ahsoka kissed Devin with Kallish accepting. Later the 4 Jedi realized there was a survivor of the crash Devin ignited his Blue-Bladed lightsaber, but quickly realized he was not a threat Devin disarmed himself and introduced himself the Wookiee introduced himself as Chewbacca. Later Chewbacca was able to contact his homeworld and many of his Wookiee brethren including Tarfful and Sugi arrived and raided the Trandoshan Compound and killed Garnac.
