Jonathan "John" Wick is a legendary hitman who previously worked for the Tarasov Mob until his retirement. Following his wife's death, John came out of retirement after Viggo's son, Iosef Tarasov, murdered his dog, Daisy (who was gifted to John posthumously by Helen to help him grieve), and stole his car during a home invasion. He succeeds in his quest by killing Iosef and eventually Viggo before requiring his car from Viggo's brother Abram Tarasov.

John is the titular main protagonist in the John Wick franchise, appearing in John Wick, John Wick: Chapter 2 and John Wick: Chapter 3 – Parabellum. He will also appear in John Wick: Chapter 4, and likely Chapter 5 as well.
