C1-10P, better known as Chopper, is an Astromech Droid owned by Hera Syndulla and one of the tritagonists of the 2014-2018 television show Star Wars Rebels. He made his live-action debut in the 2016 film Rogue One: A Star Wars Story as a cameo character, and a supporting character in the 2023 Disney+ series Ahsoka.
He has been described by the creators as being lazy, belligerent, rude, grumpy, and cantankerous as well as frequently ignoring his crew's orders and being much more content to do things his way. In contrast to the more lovable and openly heroic R2-D2, Chopper is a much more apathetic individual and nowhere near as easy a character to get along with.
Nevertheless, he still serves as the repair droid on the ship Ghost during its fights against the Empire and is also very loyal in spite of his many flaws. Due to the crew of Ghost having little in the way of resources, Chopper is cobbled together from a variety of pieces and as such is nowhere near as "sleek" as many later droid models, or even his fellow astromech R2-D2.
