8. Heihachi Mishima - Tekken
Inventor of the King of Iron Fist Tournament (just rolls of your tongue, doesn't it?), Heihachi was for a time the eldest Mishima going, fathering not only the devil gene-infused Kazuya, but lady-favourite grandson Jin too. Yes, the feather-headed volcano-dunker ended up training his own kin up multiple times, only for 'family issues' to arise both times, and set them both on the path of hatred seemingly for the rest of their lives. Hang on a minute though... Well, let's see. Firstly he doesn't use any of his wealth to look for a cure for his demonic son, even after the devil gene is clearly manifesting inside him - electing to chuck him in a volcano to quell the process instead. He even smiles as the only-naturally-occurring phenomenon erupts, despite it clearly showing some sort of reaction has taken place, and forgoing that, when the same thing happens with his grandson, his reaction is to start another tournament and have a good ol' martial arts showdown. Just shoot him, shoot him with a massive gun. You're Heihachi Mishima, the only other thing you're spending cash on is the trip to Japan to star in Soul Calibur II - you can totally afford a hitman. Oh, and he kind of straight-up forgets he has a monstrous father living under the family home, who promptly comes back to life with a mouth for a chest and an entire King's Quest worth of skeletal bones to pick in Tekken 5. Definitely a strong indication Heihachi drops the ball regularly when it comes to Secret Santa.
