Black Hook is intimidating, prideful, and dramatic, carrying himself like a true space pirate captain. He has blue armor and a pirate hat. An imposing design that matches his name. Ambitious and power-hungry, he often acts arrogant but secretly values his crew. When talking, he’s loud, theatrical, and commanding, often making threats or grand declarations while sounding overly confident.

Buster Gallon is intelligent, calculating, and highly strategic, often serving as the brains of the crew. His design appears more technical and heavy-duty, reflecting his inventor role. He prefers planning over reckless action and can be sarcastic toward impulsive teammates. When talking, he’s analytical, dry, and slightly smug, often explaining plans or correcting others with visible annoyance.

Buffalo Crush is the powerhouse of the crew. He has pink plating with gold chains on his wrists. Though intimidating and stubborn, he can be surprisingly simple-minded and loyal. He tends to follow Black Hook’s lead without much questioning and prefers action over strategy. When talking, he’s blunt, loud, and straightforward, often speaking in short, confident statements or complaints. He’s also a big eater. Really hungry most of the time. Mainly eats/absorbs the energy out of generators

Jun has fair skin, barely visible freckles, unkempt blue hair and azure blue eyes, and wears his Metal Breath on his left arm. He is very expressive, easy to anger and prone to mood swings. He maintains thrill and excitement on his journeys, displaying extroversion around many of his comrades and classmates. He is usually on a whim; he acts before speaking and barely thinks ahead. Never has he thought of his Metal Cardbots as his subordinate, only as his friends.

Blue Cop, while acting cold at times, is a thoughtful and caring Cardbot who only desires coexistence along other humans and Cardbots. He studied human culture in-depth while learning how to blend in. Despite this, he can be clumsy at times, and relies on Jun Grant to command his actions in battle. Also remains by Jun’s side most of the time.

The Metal Breath is a wristwatch-like device that seals Metal Cardbots into Metal Cards and allows Jun to summon, command, recall, and communicate with them. Cardbots are sealed after defeat (“Change Up”) and summoned with their weapon cards (“Set Up”). Jun can issue commands, communicate remotely, scan Cardbot data, transfer cards, and even strengthen Cardbots through stored energy. Though meant to build trust, some Cardbots resent the Metal Breath for forcing obedience, seeing it as a loss of freedom. The device’s current holder is Jun Grant.
