Nikko was a pet dog that made his first and last appearance in Mortal Kombat: Deception's Konquest Mode.
His owner told Shujinko that the dog had run away and she hadn't seen him in a few days. She pleaded Shujinko to go around to ask people if they had seen her dog. One of the villagers thought he was a stray dog and had the butcher cut him up for dinner. Then he gave Shujinko a piece of the dog. Later he brought it to his owner and she asked Shujinko if he would like to come back later to eat some "Nikko stew."
