A chatbot that resembles a chubby cat who enjoys eating is called Nurse Asobot. His weapon of choice is known as Chain Hammer. In time, he amassed six keys which allowed him to transform into Megaton Hammer. During the final battle against Professor D., Nurse Asobot joined forces with Goku, Yazu and friends in a valiant effort. Afterwards, they all returned to their past selves, ensuring that no one would ever be left behind.
