Also known as: デビル一八, デビルカズヤ
The alternate form of Mishima Kazuya, transforming thanks to the Devil Gene. Appears from Tekken 2 on as a separate playable character, and is merged into Kazuya in Tekken 4, enabling him to tap into further advanced devil forms in subsequent entries, whether Blood Vengeance, Tekken 7 or Tekken 8.
