"Heihachi Mishima… is dead." The line Tekken fans have now heard in-game twice, along with director Katsuhiro Harada spending the last few months insisting that The King of Iron Fist was well and truly gone.
I damn-near believed him, too. After all, the end of Tekken 7's story sees Heihachi defeated at the hands of his son, Kazuya Mishima, before being tossed into a volcano in what can only be described as a real "tit for tat" moment. Tekken 8 ends up loosely dancing around his missing status and, bar Raven repeating his infamous Tekken 5 line, it's never explicitly confirmed if he really had Dor'd his last Ya.
