Initial development for ' film chose Alpha-17, featured in the ' comic, to be the principal clone trooper character. However, because Anakin Skywalker, Ahsoka Tano, and R2-D2 (Artoo) were also principal characters, "Star Wars" creator George Lucas felt Alpha's name created too much alliteration between the main cast, and a new character, Captain Rex, was created instead. The name "Rex" was chosen by Lucas. Previously, the name Captain Rex was used for the error-prone rookie droid pilot RX-24 of "Star Tours", who replaced an earlier concept of an unpredictable and risk-taking Clone Wars veteran.
