Sol, a robot character unique to the Lensman anime adaptation, serves as a crew member aboard Kimball Kinnison's patrol ship. Functioning as one of Kinnison's primary mission companions, Sol operates as a supporting figure within the Galactic Patrol team dynamic. The character provides operational assistance aboard the spacecraft during confrontations with Boskone forces. Sol appears in the 25-episode *Galactic Patrol Lensman* television series (1984-1985) and the edited compilation film *Lensman: Power of the Lens* (1987). Created specifically for the anime, Sol does not originate from E.E. Smith's original Lensman novels. No documented background details, origin story, character development arc, narrative progression, technical specifications, or contributions beyond general crew activities exist for the character.
