A yellow excavator who is prickly and cynical but becomes infinitely gentle and warm in front of animals, especially cats. He has blue eyes. While he is a Metal Cardbot who occasionally jokes around with those he is close to, he shows no mercy and resorts to violence against anyone who mistreats animals; he has the vibe of a kind-hearted young man whose methods are just a bit rough. He has exceptional hearing, allowing him to detect ultrasonic waves that other Metal Cardbots cannot. However, he is so sensitive that vibrations or loud noises easily cause headaches or even fainting. As his headache worsens due to the persistent ultrasonic waves, he hides in the forest to avoid worrying anyone, but the waves continue to plague him even there...
