  • Kung-Fu Chicken Noodle - A Cantonese worker who gained super-powers (and an armored soup can, which he wears) after falling into a vat of chicken noodle soup in a failed suicide attempt. Due to both his ability inside the ring (including the feared five-fingered chowder fist) and the fact that he has killed at least two Kaiju, he is considered one of the most dangerous kaiju on Earth.
