CC-2237, nicknamed «Odd Ball» and also known as Davijaan, was a Clone Commander and pilot during the Clone Wars who participated in campaigns such as the Battle of Teth, the Battle of Umbara, the Battle of Coruscant, and the Battle of Utapau. A skilled pilot, Odd Ball flew an assortment of various starfighters including a V-19 Torrent starfighter, a BTL-B Y-wing starfighter/bomber and an ARC-170. During the Clone Wars, Odd Ball often served under the command of Jedi General Obi-Wan Kenobi.

A human male clone of the bounty hunter Jango Fett, CC-2237 was 1.83 meters tall and had browneyes. He proved to be a skilled pilot during the Clone Wars and was apologetic towards Obi-Wan Kenobi when the Jedi provided assistance at the Battle of Teth.

Initially during the Clone Wars, Odd Ball donned standard Phase I armor for all clone trooper pilots. Later on in the war, he switched to the Phase II variant which featured a fully enclosed helmet and breathing apparatus. However even further on in the war his armor changed yet again when he adopted the newer open-helmet design, which he wore during the Battle of Coruscant.

CC-2237 was portrayed by Temuera Morrison in Star Wars: Episode III Revenge of the Sith. He also appeared in the Star Wars: The Clone Wars film and television series, in which he was voiced by Dee Bradley Baker.

In Star Wars Helmet Collection 45, predominantly in the first half of the magazine, Odd Ball is first referred to as a Clone Commander. In the second half of the magazine, the rank changes to Clone Captain. Because Star Wars: Complete Vehicles also refers to him as a Clone Commander, this article assumes that the rank of Clone Captain is erroneous.
