The pilot of Tobot X. Now a 5th grader, but his style as a model student who excels in his studies remains unchanged. He enjoys logic, has a great interest in math and science, and knows a lot for his age. The Tobot system developed by his father, Franklin, is also one of his areas of interest. He is a rational boy with a strong sense of responsibility who, unlike his twin Kory, always deals with situations calmly, though he sometimes appears to be lecturing others when explaining what he knows.

Ryan's twin brother. The pilot of Tobot Y, also in 5th grade. He still hates studying and loves to play, but he has added a tendency to act like a know-it-all now that he's a 5th grader. The gap between his excessive boasting and his lack of effort is filled by his sly attitude and smooth talking. He often shows a shameless side, such as showing interest in other Tobots in front of his own Tobot Y, but deep down, he is a very affectionate and sincere type.

The pilot of Tobot Z. Although he is in the same 5th grade, he is slightly taller than Ryan and Kory, making him look more mature. His left arm and left leg are robotic. He has a taciturn personality and doesn't express himself much, but he is thoughtful and has a delicate side that secretly cares for his family and friends. Worried that Z might disappear because its Mind Core is damaged, he keeps Z at home and instead asks his father, Limo, to strengthen his left arm, becoming a 'Super Boy'. He has a chic personality. 12 years old (5th grade) Side: Does not believe you

He is so timid that it's almost suspicious. He is extremely reluctant to communicate with people he meets for the first time, and even when he tries, he often struggles because he is unfamiliar with expressing his feelings directly. Beneath this timid personality, a righteous side is hidden. 10 years old Side: Believes you

A curious 3rd-grade elementary school boy who lives across from Dylan's house. He was unable to participate in a soccer training trip because he injured his leg during club activities, and since his mother is often away from home to care for his hospitalized father, he spends a gloomy time alone. During this time, he meets Tobot Z, who is in a similar situation, and they develop into friends who empathize with each other's pain. 10 years old Side: Does not believe you

Extremely ugly. Uses profanity when backed into a corner. Dislikes and hates you.
