He has a prickly personality and grumbles quite a bit, but he always gets the job done. He is the official tsundere of Hello Carbot. Because of this, he often ends up being the 'pushover' among the Carbot characters (catching mosquitoes is a prime example). He possesses exceptional observation skills and speed. He is also particularly good at swimming.

Hot-tempered and full of bravado, he prioritizes style and flair above all else. He puts on a show even while fighting. "Did I look cool? How was my form?" He strikes a pose even when firing a gun, and performs a stylish spin after an attack... followed by incredibly cheesy lines. He is a creative Carbot who strives to find new combat methods rather than sticking to conventional ways. Instead of performing ordinary attacks like other Carbots, he tries to find his own unique attack style. Heat Beam Fires a scorching thermal ray. At-Tteu Beam A beam that makes the target's mouth feel hot, as if they ate something scalding. Detective Self-Defense Possesses excellent hand-to-hand skills similar to Judo, Boxing, and Kung Fu.

The leader of the Star Guardians and a fire truck Carbot. He carries a Fighter Vehicle on his upper section. The Fighter Vehicle acts as a water cannon when attached to Fire Star, and becomes an autonomous fighter jet when separated. In critical moments, Fire Star shouts "Prepare the Water Bomb!" and fires the water cannon while holding the Fighter Vehicle directly in his hands. Weapon Types Ice Autocannon: Rapidly fires capsules from the Ice Autocannon held in his right hand. As the capsules burst, liquid nitrogen is released to lower the temperature and extinguish fires or freeze enemies.

A powerful tank-type Carbot equipped with a drill and a chainsaw, specializing in disaster relief. Like Poly Star, he uses a repetitive speech pattern, speaking with a melody like song lyrics. His personality is as bold and positive as his actions. He has a strong will to break through any obstacle, but is sometimes reckless to a fault. This occasionally puts the team in danger. When the Star Guardians combine, he forms the two feet.

A mysterious wizard Carbot who displays various abilities using the cloak on his back when transformed. He uses the cloak to fly, hide like an invisibility cloak, or block attacks as a defensive shield. He is always quiet and provides wisdom by suggesting solutions. He uses telekinesis like magic, controls the forces of nature, and can teleport. Sometimes, he informs Chatan about future events in advance.
