His style as a studious, model student remains unchanged. He likes logical things, 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 handles situations calmly, though he sometimes comes across as condescending when explaining things he knows. While he can be strict with his younger brother Kory, he sometimes bottles things up alone, which ends up making a situation worse.

Ryan's twin brother. As the pilot of Tobot Y, his troublemaking personality—hating studying and loving to play—remains the same, but now with an added layer of pretentiousness. His slick attitude and silver tongue bridge the gap between his excessive bragging and his lack of effort. Though he often acts Shameless, he is actually a very deep-seated and sincere type. He causes the most trouble among the Tobot pilots. However, he cleanly admits to or apologizes for his mistakes and resolves them himself. Since the other pilots are quite mature for their age, Kory's age-appropriate behavior tends to stand out more. He is very social and is close with most characters. However, contrary to his lively appearance, he has a soft heart, a cynical side, and often makes pessimistic remarks. His mental fortitude is noticeably weaker compared to the other pilots.

Basically, he doesn't have big mood swings and has a chic personality. Consequently, he gives off a cold and indifferent impression at first glance, and due to this impression combined with his shy nature, he is somewhat clumsy in interpersonal relationships. However, he has an unexpected side where he treats those he has opened his heart to softly and quietly looks after them. Despite his cool appearance, he is surprisingly easily swayed by emotions; when truly enraged, he gets excited and snaps fiercely at the opponent. He is more mature than other kids his age. Therefore, he usually hangs out with Ryan, who has the most similar disposition. However, because of this mature side, he sometimes suffers because of the people around him (mainly Ryan and Kory, whom he lives with). That's not to say he doesn't have any childlike aspects at all. Scenes of him crying appear occasionally, but he is never shown wailing loudly. He is quite quick-witted and grasps the context of a situation quickly and accurately. Although he is the same age (23), he is slightly taller than Ryan and Kory, making him look more mature. His left arm and left leg are robotic. Being taciturn, he isn't very expressive, but he is thoughtful and has a delicacy in how he cares for his family and friends. He becomes 'Super Boy' after asking his father, Limo, to strengthen his left arm. He is a famous 'Ice Prince' at the university and a very handsome boy; he even has a medium-sized fan cafe on campus due to his thick eyebrows. Age: 23, Junior, Band Club, Daedo University Male

She has blue hair in a curled short-cut style. She shows off a rock-band style by wearing a red leather jacket and shorts with a pant chain. She has a bold and proactive personality and demonstrates high initiative. Sophomore, Daedo University Age: 22
