Usually stays inside the chip. In car form, he is a red Hyundai Santa Fe. When transformed into a robot, the car's hood is positioned on his chest. His face is a visor type, and instead of a movable mouth, the Carbot mark is engraved in red. His triangular yellow eyes glow when he speaks. His legs are formed by the trunk of the car splitting in half; the upper legs are white, and the lower parts are black and red. His arms are formed from the two front doors, with the door panels on the outside and a tire attached just below each shoulder. Ace's techniques include "Top Attack" (launching the two tires from his arms), "Water Cannon" (firing a high-pressure stream of water), and "Handy Cannon" (firing the cannon gun he holds in his hand). Though he sometimes grumbles (e.g., "I am Carbot Ace. I cannot do this."), he has trouble saying no and always helps more actively than anyone. He speaks with a slightly solemn tone and a tiny bit of bravado, but he has a kind heart, and that kindness is subtly reflected in his speech. He is also a character who provides unexpected humor. He is Guest's first robot and is the closest bot to Charlie.
