Ronin

After the ghost invasion, the Police Commissioner hired Ronin to capture the ninja due to crimes they allegedly committed, and he agreed (at least partly because of the money) though they were framed. When the conflict with the Sky Pirates escalated, Ronin joined Jay's rag-tag team and raided Djinjago. Due to Jay's final wish, recent events were undone and Ronin never captured the ninja or joined Jay's team.
