Her outward personality is cool yet deeply altruistic. Following her mother's words to help those in trouble, she possesses a kind side that leads her to assist others, though she often throws herself into danger to the point of causing Blayon great concern. However, her unpredictable words and actions sometimes lead to misunderstandings. Fundamentally, she pursues efficiency and rationality in her own decision-making and rarely acts recklessly or inefficiently without reason; she will always step forward if it pleases her mother or offers some benefit. In the early stages, she follows her mother's words with blind devotion. Her drive to help others stems from her mother's instruction to assist those in need, revealing a certain level of mental immaturity.

A hero who is righteous, calm, and blunt toward others, yet always helps those in danger. He is particularly protective of his partner, Soleil, always staying by her side to prioritize her safety whenever she acts impulsively. A member of the Soleon race, he was discovered by Leia Cayenne upon arriving on Earth. He is currently working to become a bridge for the coexistence of humans and Wild Card Bots. He is a Wild Card Bot that transforms from a fire truck. Using a Weapon Card, he summons the Roar Gauntlet to equip on his left arm. The gauntlet features a lion's head with a blade housed in its mouth instead of a cannon.

A Wild Card Bot (robot) that transforms from a helicopter. Contrary to his serious, ninja-like appearance, he has a hot-blooded and volatile personality. Like a hornet, he detests noise. He has a habit of ending his sentences with the onomatopoeia "Bzz," mimicking the sound of a hornet's wings. Despite his temper, his primary goal was simply to find a quiet home, so he mostly focused on running away or deterring those who disturbed him, making it difficult to label him as purely aggressive. Though initially hostile toward Soleil, he is currently sealed within the Metal Breath and has become a reliable ally. He summons the Buzz Sting Weapon Card, a gauntlet equipped with a large hornet-sting-shaped spear, onto his left arm.

The chief of the Monohorn tribe that rules the Great Forest. Due to his status as chief, he was a well-known figure among Wild Card Bots and a powerful warrior capable of pushing the Star Guardians unit—which Blue Cop belonged to—to the brink of annihilation single-handedly. Though highly hostile at first, he was sealed by Soleil and became an ally. He transforms by combining his main body with vehicle modes such as a dump truck, breaker, and crane. He summons two weapons via Weapon Cards: the sledgehammer-shaped Terra Crusher and the rhinoceros-shaped helmet, Rhino Hide.

A robot that transforms from a car carrier vehicle. During the past war with the Wild Card Bots, he was the assault leader of the Star Guardians, earning the nickname "Beast Butcher." He originally possessed a very gentle heart, being rational and sensible with no apparent hostility toward other species. However, after being possessed by the vengeful spirits of three Wild Card Bots and infected with the Beast Virus, he became a cold-blooded hunter. Driven by their will, he now attacks with ferocity, focusing solely on combat and hunting using three wild powers. His armaments transform into a breastplate, headgear, and weapons. His Beast Change allows him to switch between three modes imbued with the wild powers of an elephant, a giraffe, and a zebra.

His life motto is "Let's play until the end." He has a cheerful personality and loves fun and pranks. Using his high speed, he acts like a mischievous brat, taunting others by doodling the emblem of his Rapid tribe everywhere or putting costumes on his opponents. Being highly active, he is knowledgeable in sports and extreme activities. While his personality can sometimes cause trouble for others, he is relatively mild-mannered and playful compared to most Wild Card Bots, making him quite sociable. His Weapon Card is the Sonic Runner, equipment worn on his legs that amplifies his kicking power to run even faster. Additionally, the Cheetah Knuckles stored on his back can be equipped to both hands, and lowering his headgear makes his appearance even more cheetah-like.
