Dr. Rafael, occasionally known as Dr. Kane in adaptations, is a scientist pivotal to events after the original Science Ninja Team series. Held captive at Galactor headquarters, he conducted covert experiments in space communication. These experiments unintentionally drew Leader X to Earth, an act stemming from scientific curiosity that generated controversy. He survived Galactor's initial downfall and escaped. Fleeing Galactor, Dr. Rafael discovered Joe Asakura's body near Cross Karakorum following Joe's sacrifice. He transported Joe to a hidden facility and used advanced cybernetics to revive him. This extensive remodeling transformed Joe into a cyborg, a living weapon specifically designed to counter Leader X. Dr. Rafael justified this as necessary for Earth's survival, leveraging Joe's hatred for Galactor and combat skills. He kept Joe's cyborg nature and condition secret from the Science Ninja Team upon Joe's return. Dr. Rafael also created the Micro Space Bomber, the only effective weapon against Leader X, presenting it as both his responsibility and a gift to the world. His operations extended to establishing a hidden cyborg colony where he conducted further experiments on subjects like Cathy and Wulfe, exploring human-machine integration. These actions defined his morally complex role, balancing technological drive against the greater good. His past contributed directly to the creation of Gel Sadra. Aboard the Queen Margaret during Leader X's attack, which caused mass casualties including Dr. Pandora's husband and the presumed death of her child Sammy, Dr. Rafael survived. Unbeknownst to Dr. Pandora, Sammy also survived, was captured by Leader X, mutated, and rapidly aged into Galactor's new commander, Gel Sadra. This indirectly linked Dr. Rafael to the sequel series' primary antagonist. Dr. Rafael's motivations blended guilt over bringing Leader X to Earth with a relentless pursuit of scientific solutions, regardless of ethical cost. His manipulation of Joe exemplified this, viewing the revived Condor as an essential tool for Earth's survival rather than a human being. His ultimate fate, alongside the resolution of his role with the cyborg colony and against Galactor, remains unexplored within the sequel series and its documented adaptations.
