Manny (マニー): Voiced by Kōichi Yamadera (山寺 宏一). Yamadera is often called the "man of seven colors" for his incredible range, also known for voicing Spike Spiegel in Cowboy Bebop and Disney's Donald Duck.

Sid (シド): Voiced by Hikari Ōta (太田 光). A prominent comedian and member of the duo "Bakushō Mondai," Ōta brings a manic, fast-talking energy to Sid that mirrors the character's original English performance while adding local comedic flavor.

Diego (ディエゴ): Originally voiced by Naoto Takenaka (竹中 直人) in the first two films. In later installments, such as Continental Drift and Collision Course, the role was taken over by Unshō Ishizuka (石塚 運昇) and later Hiroshi Shirokuma (白熊 寛嗣). Key Supporting Characters
