Robert Ryan is a fellow pilot in the Cosmo Ecology space force, operating alongside Tsutomu Saki. His background prior to joining remains undisclosed. During an investigation of satellite wreckage, Ryan becomes pinned by hostile fire from the outlaw soldier Jimmy Dean, forcing the reluctant pacifist Saki to intervene. This situation acts as a catalyst for Saki's decisive action.

Ryan depends on Saki's technological expertise and unconventional problem-solving to overcome their adversary. Together, they successfully incapacitate Jimmy Dean's combat capabilities non-lethally. Both pilots then directly approach Dean, attempting a peaceful resolution by taking him into custody to prevent his self-destruct sequence, underscoring nonviolent conflict resolution.

Ryan demonstrates professional competence during space combat operations defending waste transport missions against outlaw elements.
