Rokusho is a KWG type Medabot build to have the appearance of a stag beetle. He was build by Dr. Hushi before Medabots were known to the rest of the world. It's highly possible that he was the first modern Medabot build by a human. He lived with the professor whom he saw as a father figure and his best friend was a robot parrot named Baton. After a terrible fire destroyed Hushi's house and seemingly ended the professor and Baton's life, Rokusho wandered the world alone, trying to find answers to why he had lost everything he loved as well as the purpose of his creation.
In the manga
Rokusho in the manga has similarities to his anime counterpart with the main difference being that Dr. Aki became his owner after Hushi died. He is a very polite and patient robot who enjoys reading, but his patience has a limit as shown when Aki and Henry exchange Medabots for a day and he threw a tantrum after Henry and his fiends treated him as if he was a dressup doll.
Rokusho is an old and wise Medabot who prefers being alone. Unlike other Medabots, he finds no joy in combat and consider Medabots like Metabee as childish for fighting for no other reason but to fuel their ego. But he is skilled in combat and is extremely focused, making him a formidable swordsman. Rokusho respects nature above everything else and also seems to enjoy studying insects and how they live. He especially admires ants for making a society similar to that of humans.
Powers and Abilities
Rokusho body is build for swordsmanship. His fighting style is based on his speed and uncanny accuracy. He has antennas on his head that boosts his accuracy, meaning that he almost never misses his target once he gets close enough to strike them with his blade. His signature move is the Chanbara Sword where he with record speed slices up his opponents. Rokusho is also very nimble which gives him a huge advantage when he is up against Medabots who relies on long distance attacks.
Rokusho has no Medafighter, meaning that he is alone in combat, but he has through his many years gained wisdom and fighting tactics.
Rokusho's medal is a legendary Kuwagata medal, meaning that his reflexes and fighting skills are superior compared to other Medabots who uses "normal" medals.
Another thing that separates Rokusho's medal from "normal" medals is that he can use the Medaforce, an energy-based attack that taps out an huge amount of energy from his medal and fires it out of his body as a powerful laser beam.
