Possesses a kind and altruistic personality. He helps Metal Cardbots he meets for the first time with all his heart, and despite calling the Metal Breath he obtained a 'token of friendship,' he has never once acted coercively. He calmly persuades Metal Cardbots who cause trouble due to maladjustment on Earth through dialogue until the end, and even when he is humiliated or bullied in front of someone he likes, he shows a magnanimous side by shaking it off quickly without holding a grudge.

Crest's twin sister, she is blunt yet incredibly 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 sometimes cause misunderstandings. Fundamentally, she pursues efficiency and rationality for herself when judging situations and never acts recklessly or inefficiently, but it is revealed that she will always step forward if it makes her mother happy or provides a benefit. She is a mechanical lifeform.

Basically a cool personality who stays positive as long as the result is good even after going through hardships. He shows the qualities of a true leader, expressing responsibility to ensure his kin live freely, but in the beginning, like other Wild Cardbots, he was very bellicose, did not avoid fights, and did not seek pastoral peace.

A female Metal Cardbot who is quite popular even outside the fandom. She is very playful and is a Wild Cardbot based on a cheetah, so she runs extremely fast. She speaks in a Busan dialect.

Soleil's soulmate who uses fire (though it's a mystery why he breathes fire despite being a fire truck). He is on the larger side and prioritizes Soleil to the point of being a superfan.

His way of speaking is a bit rude, but he's a good kid. He seems to bicker quite a bit with Tygun.

This one also has a rude way of speaking and loves fighting (a total battle maniac). He transforms into a tank.

He said he liked being independent, but now he's forming a team to prepare for a subjugation mission against the Calamity (T-Jae). He is strong and a tsundere.
