Mule is a god whose intelligence surpasses that of mankind, and within his robot Mosco, he uses beep sounds for communication. As Mosco, he usually appears very silent within his suit, having no verbal dialogue with any of the other characters whom he interacts with. However, when he does communicate from his suit, he beeps in 8-bit tones with his robot's robotic eye flashing brightly. Like most other Gods of Destruction, Mule has a low tolerance of failure.
