M-OC

M-OC is a hunter droid built by the Emperor Palpatine in Lego Star Wars: The Freemaker Adventures. Darth Vader has a competitor relationship with it.

History
After the Freemakers defeated Naare and fled with the Kyber Saber, Emperor Palpatine built the M-OC to chase Rowan Freemaker, because he thought he still had the Kyber Saber. During the hunt it worked logically, and yet many times Rowan Freemaker managed to escape it. But when the Arrowhead graduated and the Rebel Alliance used it to overthrow the Galactic Empire, Palpatine gave it and Vader the task of grabbing Rowan Freemaker together. But Darth Vader shattered it, captured Rowan Freemaker and took him to Coruscant himself. But it managed to rally itself and return to Coruscant, and when it took over the Arrowhead, it was going to kill Rowan Freemaker. But Freemakers and Quarrie succeeded in destroying the Arrowhead by colliding with the StarScavenger, but M-OC managed to take the Arrowhead's Kyber crystal to the Death Star. But when Rowan Freemaker met it for the last time with the Death Star, he used Kyber Saber to fight it. The battle was fierce, but Rowan managed to destroy it and the Kyber Saber once and for all.
