lolno he didn't.
When Heihachi threw Kazuya's punk ass into a volcano in Tekken 2, he died like the cowardly whoreson he is.
He wasn't present in Tekken 3 because his lifeless corpse was being revived by G Corporation. He was back to full fighting strength in Tekken 4.
Akuma breaks islands. Kazuya isn't shit on that.
