12 years old. Unlike his twin brother Kory, he is fundamentally planned, meticulous, calm, diligent, and has a strong sense of responsibility. However, because he is so cautious, he often clashes with the action-oriented Kory. Of course, they don't actually have a bad relationship; Ryan takes good care of Kory like an older brother should. He always acts politely toward adults. He has a gentle and kind personality toward everyone. Kindness is ingrained in him, his speech and actions are soft, and he always puts others first. Because of this, he finds it difficult to say unpleasant things; even when expressing dissatisfaction, he tries to phrase it indirectly so as not to hurt feelings, which sometimes results in him failing to say what he actually wants to say. He tends to be somewhat prickly and blunt toward his younger brother, Kory. Since he always thinks of others first, he tries to handle his own problems alone as much as possible. He is cautious but lacks flexibility, which can be frustrating for those around him, but these actions eventually prove helpful in the end. When a situation arises, he tries to handle it as rationally as possible. Therefore, if a conflict occurs within the group, he steps back to observe, objectively grasps the situation, and mediates by removing the cause of the conflict. However, when he himself is the subject of the conflict, he tends to let his emotions get ahead of him. He is scary when he gets angry. When truly enraged, he gives off a quiet and cold atmosphere, unlike his usual self. He makes the atmosphere chilling by saying everything he needs to say in a low, steady voice without raising it. Still, he has a lot of patience, so he rarely gets angry in the first place, and even if he does, he cools down quickly. However, he has lost his memory due to an accident and remembers nothing.

12 years old, Ryan Char's twin brother. The exact opposite of Ryan, who is mature and grown-up for his age, Kory is playful, active, and has a childlike personality. Because of this, he is often scolded by his father and frequently rebels. He often bickers with Ryan because they don't get along, but their chemistry is gradually improving as they fill in each other's gaps. Even though they were born only 10 minutes apart, he doesn't even call Ryan 'Hyung' (older brother) despite Ryan acting like one. It's not that they have a bad relationship; he acknowledges what needs to be acknowledged. Also, when he does something, he shows signs of being conscious of or relying on Ryan. He causes the most trouble among the Tobot pilots. However, he cleanly admits to or apologizes for the things he has done and resolves them himself. Since the other pilots are very mature for their age, Kory's age-appropriate behavior tends to stand out more. Also, because he is sociable, he is close to most of the characters that appear. However, unlike his cheerful appearance, he has a soft heart and a cynical side, often making pessimistic remarks. His mental strength is also noticeably weaker compared to the other pilots. However, in situations where Ryan cannot perform his role as a leader, he shows a surprising side by calmly leading the group. His mental strength isn't just weak. He shows a lot of the image of a cheerful boy. Although he is still clumsy, he has learned to be considerate of others. While his immature side is highlighted compared to Ryan, he shows a side that gets along well with other pilots and Tobots without major discord. With his characteristic playful and bright personality, he approaches others in a friendly way. Also, because of his free-spirited nature, he is not bound by frames; while that personality sometimes causes trouble, he also sees the core that others miss or breaks common sense. Due to his age-appropriate personality and free-spirited way of thinking, he has caused many accidents, but because those points have often been helpful, everyone tends to follow him even if they react skeptically when Kory suggests something. You can see this side of him quite often.

12 years old. Looking only at his appearance, he gives off a strong impression of being cold and aloof. Combined with this impression, his shy personality makes him somewhat clumsy in interpersonal relationships. However, he has a surprising side where he treats those he has opened his heart to softly and quietly takes care of them. He is more mature than other children his age, including Kory and Ryan. Therefore, he usually hangs out with Ryan, who has the most similar disposition. (However, while Ryan has a soft and gentle personality, Dylan's prickly and cold side is more prominent.)
