He first appears in Episode 23. He is a GenJyuKen Dragon-Fist Master and is the coordinator of the GenJyuKen. He is a mysterious fellow, hiding behind the scenes. For a long while, he only made his presence known to Mele, whom he sneakily manipulated. He told Mele that Rio will obtain DoRinki and defeat Maku. Ron was the one behind Gou's transformations into the werewolf until Bae's interference stopped that. From that point, he did consider the Gekiranger worthy adversaries for Rio. When Rio headed to the Beast Origin Village, Ron took the guises of Jan, Gou, and Master ShaFu to inform him he must obtain the SouJyuTo first. Ron manipulated Mele into stealing the SouJyuTo from Ken in a underhanded manner, leading her to establish her Dorinki. When Rio and Mele both left for the land, Ron made his presence known to the three Kenma and teased Maku. Maku was the only one who knew him. In Episode 35, he murdered Rageku, who taught he was just a mere boy but when he showed her his golden Beastman form, it terrified her and she recognized it. He then revealed his identity to Rio, luring him into GenJyuKen. His name is based on Long, the Mandarin word for Dragon.
In Episode 41, Ron requested to go out in conquer the world. Rio put him in his place and told him to show him his power. Instead, Ron sent his Phantom Twins, who seemed to get the job done but where ultimately were defeated by the Gekiranger. In Episode 44, he sent Suugu after GekiRed, seeing him as a roadblock. Jan was able to get to his father Dan inside of Suugu. This angered Ron, so he changed into his Beastman form and shot an arrow towards Jan. Suugu stood in the way and was mortally wounded. In Episode 45, Jan defeated Rio and Rio grew huge in the GenJyuOu form. This was part of Ron's plan all along. Mele, seeing how much Ron was enjoying it, she knocked him down. She screamed for Rio and he stopped and returned to normal. This surprised Ron. Whhen the Gekiranger were going to approach Rio, Ron attacked them and approached Rio. Before Rio could question Ron, Mele dived in and took him away. Ron followed them and tried to stop them in streaks. In Episode 46, it was discovered that he not only killed Rio's family when he was young, that propelled his darkness, but Ron also killed Jan's mother in front of him.
Ron revealed to everyone he was responsible for Maku creating RinJyuDen and wanted him to be a God of Destruction, but once he was sealed, he had designs for Rio. Ron actually hates his human form, as he is immortal and dislikes humanity for their mortality. Never being able to die, he is bored and wants some 'fun.' When Ron sent Mele a death blow and Rio blocked it, Ron finally realized Mele was what tied Rio to his humanity. Ron takes her a unconscious Mele hostage in a vain attempt for Rio to resume his part in the master plan. Mele is rescued and the seven destroy Ron with SaiDaiGekiRinTouja, or so they believed. He returned with Sanyo in Episode 48. He swallowed Sanyo and took his true form, to be defeated by Rio. Ron survived it and battled the Gekirangers in one final fight in Episode 49. His power and himself was sealed into a ball, which now hangs around Jan's neck.
