Devil Kazuya

Devil, also known as Devil Kazuya, is a character who made his debut in the original Tekken and is one of the main villiains of the series. He is the cursed soul of Kazuya Mishima and later Jin Kazama. Originally a malevolent entity with the intent of possessing either Kazuya or Jin, one half has merged with Kazuya.

Though there are supposedly multiple 'devils' within the series, only the entity which inhabited Kazuya is referred to as 'Devil'. He is the final boss for every character in Tekken 2 except for himself, if the player uses Devil then his final boss will be Angel. Devil can take his own form or can take over the body of Kazuya or Jin to become Devil Kazuya or Devil Jin respectively.
