SolRo - 2018-10-10 context; his father is a huge asshole.
kingofthenothing - 2018-10-10 yeah, the series is pretty hilarious about this. Kazuya was dropped off a cliff by Heihachi around the age of 10 and this is just payback.
If you beat Tekken 2 with Heihachi, his ending has him dropping Kazuya into a volcano and smiling.
Heihachi's ending in Tekken 3 has him throwing his GRANDSON out of a helicopter but he's all like *frowny face*.
Xenocide - 2018-10-10 Not pictured: Heihachi standing in midair for a second, looking down, taking out a little sign that reads "YIKES!" and then falling while a slide whistle plays. He makes a little circular cloud of dust when he lands.
