K-2SO is a fictional male character who works for Rebel Alliance in the Star Wars franchise. He has been portrayed on screen by Alan Tudyk. K-2SO (Kaytoo Esso) was once a Galactic Empire droid that`s been converted to work for Rebel Alliance in their mission to steal the Death Star plans. The robot is reminiscent of the droid in Jabba, the Hutt`s palace that wanted to put a restrainer belt on R2-D2 at the time he was torturing another droid. The droid is extremely funny compared to every other comical character that has gone before.
K-2SO does share some traits that C-3PO has such as having the nack of giving chance of success percentages. He acts as though he`s human. Cassian Andor gave the K-250 an instruction to stay on the ship but he betrayed his captain which was just as well because K-2SO saved the lives of Cassian and Jyn Erso in doing so.
Where they tried to make Jar Jar Binks the comedic character in the prequels and failed dismally. They have learnt their lesson and made K-2SO into a very funny character without the stupidy acting, they just relied on his wit and one liners.
Sadly, K-2SO will not be returning for any future film as he was killed off when Stormtroopers stormed the computer control room that he was in. K-2SO was able to fight off and give Cassian and Jym Erso the time that they needed to get the item and broadcast the plans to the Rebel Alliance in orbit round Scarif.
