In the 1994 Gatchaman OVA's English adaptation, Jinpei the Swallow adopts the alias Jimmy the Falcon. As G-4, he operates as the Science Ninja Team's reconnaissance specialist and youngest member. Jinpei's early years remain mostly undefined: Jun discovered him as a toddler in the Jupiter Mountains while fleeing wartime conflict, then brought him to the Shirayuki Orphanage. They grew up as adoptive siblings before Dr. Nambu recruited them both, leveraging Jinpei’s natural agility—which made him popular at the orphanage—and, in the OVA, his self-taught hacking skills via online education. Jinpei stands at an average height for his age, with wild brown hair and a lanky build. The OVA modernizes his civilian look with a beanie and sweatshirt, slightly curlier hair, and updates his Bird Style uniform to red with yellow accents and a purple cape, replacing the classic yellow-and-blue design. The belt emblem simplifies to a central symbol instead of the "G" insignia. His personality blends cheerful mischief with responsibility: he provides comic relief yet assists Jun in her snack bar and supports teammates during missions. Jinpei dislikes academic subjects like math but excels at gaming and electronics. Key relationships define his character—he shares a close sibling bond with Jun, teasing her about her feelings for Ken, whom he views as an older brother, addressing him as "Aniki". For reconnaissance, Jinpei employs stealth and incapacitation tactics to offset his small stature against adult opponents. His weapons evolve across adaptations: original series American clackers (bolas) give way to sequels' rebound ball or swallow top (a yo-yo-like spinning top). The OVA introduces an unnamed hacking device featuring a collapsible screen and gamepad interface, syncing intel to his helmet visor via heads-up display. His mecha includes the Swallow Helico VTOL aircraft for tight spaces and, in later sequels, the Gatcha Four tank, which contributes to the combined Gatcha Spartan. The alias "Jimmy the Falcon" remains exclusive to this OVA’s English dub, diverging from his traditional "Swallow" codename. No spin-offs, films, or other series entries utilize this alias or expand upon his established origin.
