Ying Ki was the son of Ying Wai, and lived with his father in a Chinese coastal village in 1807. He is also a descendant through his mother's side of Lei Bao, a member of Sin Ji-Hun's crew.
When Ki believed his father had been killed by a pirate queen, he led the Thirteenth Doctor and her companions to his body. The Doctor observed that his wounds bore signs of hexo-toxic poisoning, and determined that he had been killed by a Sea Devil biological weapon.
Following the defeat of the Sea Devils, Ki accepted an offer to join the pirate crew. (TV: Legend of the Sea Devils)
