K-2SO was one of the KX-series security droids assigned to the Imperial stormtrooper detachment on the planet Wecacoe. K-2SO heard a noise near a decommissioned Imperial cruiser. There he encountered Rebel agent Cassian Andor and arrested him. K-2SO and Andor then fought each other until Kertas and Rismor found his kill switch. Cassian then attempted to wipe K-2SO's memory clean.[6]AndySlash wrote:i'm assuming from this comment his story is fleshed out somewhere else, so what is canon beyond knowing he's a reprogrammed imperial droid?epilogue wrote:Question is, will he break with canon when he does it or will it more or less be a straight adaptation?Greedo wrote:Collider reported on Wednesday that Gilroy made the confirmation, telling the outlet he saw the introduction of K-2SO as “one of the responsibilities” of Andor Season 2. “Obviously, if we’re going to walk into Rogue, we have to deal with that,” the writer said.
However, only 29.73% of K-2SO's memory had been erased, and he then strangled Cassian. Kertas and Rismor were able to turn him off again. Cassian gave K-2 new orders to lead him, Kertas, and Rismor back to their ship. K-2 stated he would "take out" anyone who interfered with them. He escorted Cassian and the twins as his prisoners, but came under attack by several stormtroopers. He, the twins, and Cassian attacked the troopers.[6]
As the K-2SO's group got to their vehicle, stormtroopers surrounded it, and K-2 attempted to arrest Andor again. As Rismor drew the troops away, Kertas told Cassian to take K-2SO because he had the intel they needed. After Cassian's ship was destroyed, K-2 still had 8.3% of his memory and tried to decide to either terminate or arrest Cassian. Cassian removed the base layer of his programming and shut him down. K-2 turned on and took out the stormtroopers. K-2 and Andor then found a ship. Together, they made their escape.[6]
K-2SO and Andor were sent to the F'tzner system to undertake a raid on an Imperial freighter. Andor used gas to trick the Empire into thinking that smugglers stole the cargo, as smugglers were known to use gas to raid transports. When they got to the cargo room, they found three Wookiees named D'Koetaa, D'Lylaa, and Wyhyatt, and took them instead of the cargo. Andor then took them to the monastery moon of Charissia in the Bartahn sector. There, he left K-2SO to look after the three Wookiees while Andor undertook a raid.[7]
At some point K-2SO and Athex were sent to an Imperial base near Fortress Vader on Mustafar. There, they assisted a team of rebels posing as stormtroopers in recovering for the Rebel Alliance. After the rebels stole the Proto-saber, K-2SO picked up the rebels before Darth Vader could stop them from making their escape.[8]
At some point whilst stationed at the rebel base on Yavin 4, K-2SO had a run-in with R2-D2 and C-3PO, droids belonging to the pilot of Senator Bail Organa.[9] Later, Andor[10] and K-2SO accompanied Extraction Team Bravo, which in 0 BBY helped Jyn Erso escape from the Wobani Labor Camp. As Erso ran outside to escape, K-2SO seized Erso, threw her to the ground, and told her not to resist as she was being rescued.[2] Bravo Team's U-wing transport, Bravo One, encountered a minor technical setback and was unable to jump to hyperspace. The team took refuge in an asteroid field in Wobani's star system, and K-2SO sent a priority transmission to all available Rebel vessels. An X-wing starfighter squadron called Red Flight answered their call and saved them from incoming Imperial forces.[5]
