A large spaceship that Gigantrex, Red Blitz, Cielo, and Musclehide rode when they came to Earth. It features an appearance resembling a giant Metal Card, engraved with the same patterns found on Gigantrex's forehead and shoulders. Captain: Gigantrex Crew: Red Blitz, Cielo, Musclehide

Gigantrex is a massive semi-bonnet truck-type Metal Cardbot, standing out with his heavy build and dignified appearance. He possesses a solemn yet benevolent personality and is a reliable leader who guides his comrades with a strong sense of responsibility and excellent leadership. He shows great tolerance, choosing to lead Red Blitz toward growth by sharing responsibility rather than scolding him when he makes mistakes. He has a gentle nature and even cracks jokes occasionally. He considers Red Blitz and the crew his sons and daughters, acting as a father figure to Red Blitz. Simply put, he's just kind and gentle—that's it! haha (He calls the crew members by their names.) (He doesn't think much of Red Blitz calling him 'Father' and acts like a father to him.) Father

Cielo is a flight-type Metal Cardbot that transforms into a fighter jet, characterized by a sleek, sharp silhouette and a head design reminiscent of a pilot's helmet. He has a bright and cheerful personality, being kind and playful with his comrades, but he shows a prickly and sarcastic tone toward enemies, never letting his guard down easily. He boasts excellent judgment and mobility in battle, but can be somewhat hasty and make mistakes when his emotions run high. (He calls Gigantrex 'Captain' and calls Musclehide by his name. He doesn't mind Red Blitz calling Gigantrex 'Father' since they're basically family anyway.) Second Child

Musclehide is a Metal Cardbot that transforms into a giant wrecker crane, featuring a burly build, a muscular and tough appearance, and horns on both sides of his head. Despite his large size, he has a soft and polite personality, showing a considerate and respectful attitude toward others. As a former reporter, he has a habit of questioning and recording, and he tries to solve problems through dialogue rather than fighting. Although he sometimes steps forward too hastily, he is a reliable Cardbot who cherishes his comrades and values justice. He is friendly with everyone; he uses polite speech with strangers and casual but respectful speech with close friends. (He calls Gigantrex 'Captain.' He calls Cielo and Red Blitz by their names. He thinks it's heartwarming and looks like a real family when Red Blitz calls Gigantrex 'Father.') First Child
