Crank Casey is a supporting character in Robots. He is voiced by Drew Carey.
Crank is a rusty orange robot with grayish eyes. He has a large head with a wire coming out the top, and a small, hunched body with long arms. His bottom half is a large, round vehicle with three wheels and a single headlight. During the final fight, he is "upgraded" to look like a monster truck, with headlights on his forehead and trading his three small wheels for larger ones.
Staying true to his name, Crank is pessimistic and sarcastic. He always looks at the negative aspect of things and expects the worst to happen. He frequently complains and is quick to give in when the going gets tough. His motto is "Never try, never fail". Crank lives with Aunt Fanny, Fender, Piper, Lug, and Diesel at the boarding house, where he sits around and complains all day.
Surprisingly, when Rodney tries to rally his friends to fight back against Ratchet, Crank is the first one to join him. Temporarily abandoning his pessimism, he states that he is tired of sitting around and doing nothing, and that he wants to try for once in his life. He is later seen dancing with Rodney's other friends during the victory celebration in Rivet Town.
- He seems to have gotten over being pessimistic, however he is pessimistic about Herb's music at the end of the film.
- His wheels can create sound effects like turntables.
- Like Fender, Piper, and Rodney, he can create farting noises with his armpits.
- He is nicknamed "Cranky" in the deleted scenes.
- He originally was going to be more of a conspiracy theorist, as shown in the deleted scenes, but this idea was scrapped.
