; : :Goku is a first-generation assobot whose primary mission is to locate the 49 Keys of the Apocalypse, which he believes will lead to a great treasure. His companions include Suzie, Sanzo, Tongo, Joe, and later Meeyon and Shiyon. While largely humanoid, his face is distinctly simian, a trait about which he is sensitive. He wields a magic metal "joystick" that extends at will and rides a robotic horse named Skywalker. Sanzo places a curse on him, making him physically vulnerable to women and children. After collecting six keys, his appearance changes and he gains new abilities like the "Easter Wind" and "Fire Vortex Revolution". His name, Goku, is derived from the characters for "five" and "nine". ; : :Sanzo, who awoke from a thousand-year cold sleep to prevent global destruction by collecting the 49 Keys, forces Goku on this quest, promising to remove his curse only upon reaching the final city. He wields a magical harmonica that can control, heal, and power up most assobots, though it is initially ineffective on those infected with the Destruction Virus. After he collects six keys, the harmonica's appearance changes and it gains the power to heal infected assobots. He acts as a brotherly figure to Suzie and was once the lover of Rhea, the mother of all assobots. ; : :Suzie joins the quest after losing her father in an attack by infected assobots, seeking to witness the legend he once told her. Though lacking innate abilities, she operates a flying vehicle and later discovers a unique bow that emits a sound affecting assobots, a weapon only she can wield. With this bow, she ultimately uses the Bow of the Sun to peacefully lay Ryutaro Demon's soul to rest, being the only one who understands his anguish. She chooses to return to the past with Goku and the rest of the group. ; : :A worker assobot, his face is perpetually covered in a ninja-style mask. He requires significant amounts of water to survive and is considered invincible in underwater combat, wielding a weapon known as the Feather Sword. After collecting six keys, his appearance transforms and his weapon evolves into the Feather Blade. He holds to the principle that the bandit group should never abandon each other, a belief that leads him to return to the past alongside Goku and their companions. ; : :A nurse assobot who resembles a portly feline with a fondness for eating. His primary weapon is the Chain Hammer. After collecting six keys, his appearance alters and his weapon transforms into the more powerful Megaton Hammer. He participates in the final battle against Ryutaro Demon alongside Goku and their allies. Adhering to the bandit group's principle of loyalty, he accompanies them on their journey back to the past. ; : :Meeyon is a nearly human-looking assobot who later joins Goku's group. Sanzo observes her resemblance to Rhea. She travels on a transforming pet named Saati, which becomes her hoverboard, and employs candy-based attacks like bubblegum bombs. After collecting six keys, she acquires a magical umbrella capable of flight, defense, and hypnosis. In the final confrontation, she and her sister, Shiyon, are instrumental in discovering Ryutaro Demon's weakness. The sisters ultimately choose to travel to the past with Goku and the others. ; : :Meeyon's little sister. Like Meeyon, she is an assobot and one of Ryutaro Demon's quartet. During her time as part of the quartet she used a Sitar played like a cello. She joined Goku so she can spy them in their journey. After she died due to the Destruction Virus, Sanzo revived her after his harmonica is changed by the 6 keys. She can transform or change into a pretty lady who looks like Meeyon, only with blue hair.
