Penny

Penny is a robot helper made to help people get stronger, train, or sharpen their combative abilities. She knows many different techniques and fighting styles. She is a very dangerous opponent, but she doesn't use her power or skill for evil, or to show them off. She is a really humble, calm, and wise helper. She can't die, simply because if she becomes too damaged, she'll be able to recover quickly. You go to her ruby palace to get better at fighting.
