He has a kind and altruistic personality. He goes out of his way to help Metal Cardbots he's never seen before and calls the Metal Breath he obtained a 'token of friendship,' never once acting coercively. He is a big-hearted person who calmly tries to persuade Metal Cardbots causing trouble on Earth through dialogue until the end, and he quickly shakes off embarrassment or bullying in front of people he likes without holding a grudge. Blue Cop's partner.

Jun's partner. In contrast to the passionate and eccentric Jun, he is a protagonist figure with a cool head but a warm heart. He is fundamentally calm and thoughtful. Looking only at his character keywords, he might seem like a rigid and solemn police officer who never forgives evil, but in reality, he has a soft and gentle personality. Rather than a leader who unites the Metal Cardbots, he feels more like an eldest brother who suffers in various ways because of his rambunctious younger siblings. This side of him is highlighted because Metal Cardbots with truly gentle and dignified demeanors are rare, while many have strong tempers or personalities that are far from normal.

Blayon's partner. Crest's twin sister, she is blunt yet extremely altruistic. She has a kind side that helps others, but she often throws herself into danger to the point of worrying Blayon. However, her unpredictable words and actions often cause misunderstandings. Fundamentally, when judging a situation, she pursues efficiency and rationality for herself and never acts recklessly or inefficiently in daily life; however, she will unconditionally step forward if it makes her mother happy or provides a benefit.

Soleil's partner. Unlike Blue Cop, who is righteous and kind to others, he possesses a cold and blunt personality. As a member of the Wild Cardbots who have fought wars against Metal Cardbots for a long time, he surprisingly doesn't take a highly hostile stance toward his former rivals. Strictly speaking, his stance is closer to indifference, provided they aren't a threat to Soleil's safety. He didn't even care when he saw Blue Cop, a member of the Star Guardians created to oppose Wild Cardbots, and he even wanted to express gratitude to Mega Brawler for treating his injuries. While his own goals are idealistic, he often shows cynical and pessimistic behavior toward anyone other than Soleil. This is a unique trait of Blayon; even Wild Gardi, who is on the colder side among Earth's Metal Cardbots, engages in social interaction and shows interest or comfort to others. Furthermore, since most other Wild Cardbots are positively devoted to their own goals, no one else shows such a consistently pessimistic reaction toward humans, Metal Cardbots, and Wild Cardbots alike.

Possesses a personality that seems like a mix of Shadow X and Red Blitz. Contrary to his serious, ninja-like appearance, he is actually quite energetic and hot-tempered. In the beginning, his goal was simply to find a quiet home, so he mostly ran away or kept those who interfered at bay, making it hard to call him truly bellicose. However, after being sealed, he proved his combative nature by asking Soleil to let him fight. As his initial hot-headedness subsided, his cheerful, mischievous, and competitive nature became more prominent. He also has a lazy side. Representative examples include trying to flee without fighting when his hideout was discovered in Episode 2 of W, and staying lying down in Episode 8 of W because he had no intention of joining a fight he was watching, even if it was part of a plan.

A cheerful hero with a boisterous personality, he has high self-esteem, even calling himself the strongest Wild Cardbot on Planet Machina. He seeks thrills and has a strong combat-maniac side, often picking fights with fellow Wild Cardbots and referring to himself as a 'lone beast.'

Unlike his elegant and serious appearance, he is fundamentally bellicose, a narcissist who tries to maintain an air of nobility, and a hypocrite.

As his life motto is 'Let's play until the end,' he has a cheerful personality that loves fun and pranks.

Despite his active role as the Star Guardians' assault leader, earning the nickname 'Beast Butcher,' he possesses a remarkably gentle heart.

A cold, calculating, and charismatic strategic leader with strong convictions. In the final episode of Season 2, he was defeated by Jun's group and sealed by Jun.
