Ralmophan, also romanized as Ralmophon, is a supporting character in the Dirty Pair Flash original video animation series. He appears in the second volume of the series, in an episode titled Darkside Angel, which takes place on the planet Shutajitto. In the episode, he is a person of considerable standing on that world, a VIP whose life is under threat, and the story is built around a mission to keep him safe. Kei and Yuri are dispatched to Shutajitto specifically to serve as his bodyguards, and he is the central figure of their assignment.

Ralmophan is presented primarily through his function in the story, and the episode gives little attention to his personal background, personality, or private motivations. He is not an active force in his own narrative; events happen to him rather than because of him. The key relationship in the story is the professional one between him and his protectors, since Kei and Yuri are answerable for his safety and their attentiveness determines what becomes of him. The episode also implies an enmity between him and the people who want him dead, though that conflict is handled by the agents rather than by Ralmophan himself. He possesses no notable combat abilities or special powers; his importance lies entirely in his position as a prominent figure, not in any personal capability.

The character undergoes no personal development over the course of the episode, as his presence is confined to the security operation built around him. The turning point of the story is the failure of that operation. Because of a lapse in Kei's attentiveness, the protection detail is broken, and Ralmophan is killed. His death is the pivotal event of Darkside Angel, and the circumstances surrounding it, along with the consequences for the agents who were meant to guard him, form the dramatic core of the episode.
