i was going to continue the posting feats but since T.Fury posted faster most of the Tekken 5 and Tekken 6 feats, i will post the Tekken 7 feats now
> 11:55 - 14:45
Heihachi pretty much displays that he can casually react to bullets or kicking rockets away (thing that is common even for weaker characters than Heihachi), and also casually defeats Nina
> 22:55 - 25:02
Heihachi and Nina casually react to bullets once again, with Heihachi showing that he can dodge bullets even from closer range (more hypersonic-hypersonic+ feats for him but you will see later that he is MHS+) and he also easily defeat Claudio who is the world's strongest exorcist
> 28:37 - 29:23
Jin casually destroyed a Helicopter with his Majin powers and later fired a beam fast enough to reach the sky while being not in good health condition
> 30:49 - 30:55
Lars can casually dodge bullets again (in Tekken 6, he could easily react and deflect a rocket, so, easily hypersonic reactions for him too)
> 39:27 - 39:37
even the likes of Alisa can dodge bullets without trouble
> 44:31 - 49:25
Heihachi is able to survive/tank some attacks, collide attacks and inflict some damage to Akuma in hth, he even reacted to a projectile attack from him, later, Akuma and Heihachi destroy a large group of Jack-6's, then, Akuma vs Heihachi is on, once again, Akuma uses Raging Demon on Heihachi and Heihachi despite getting rekt, he wasn't dead, Akuma decides to end this with a Hadouken and while Heihachi tried to counter it but he lost, in the end
(like it or not, it's very impressive for Heihachi from not instantly dying from Akuma's Raging Demon, it could be a form of plot armor but it's still an impressive feat regardless)
> 53:30 - 54:53
Alisa survives a grenade of Nina's from point blank which sends her flying off the building and later returns to defeat Nina but still Nina wasn't fully defeat at all
> 58:19 - 58:49
Heihachi got buried through many dozens of rubble while was also several miles away from the Mishima Dojo in his battle with Akuma, but still, Heihachi was able to survive
> 1:02:07 - 1:07:30
it's time for Akuma vs Kazuya, base Kazuya despite fighting fairly well, he easily loses, then Kazuya transforms into Devil Kazuya, while he was fighting with Akuma, a powerful and fast beam from Heihachi's Satellite weapon (which was created from Dr Abel and back in Tekken 3, it had power enough to create a nuke like explosion like in Gunjack's ending in Tekken 3) is unleashed and destroys the large building that both Kazuya and Akuma were fighting, Kazuya was able to easily survive though
so, Kazuya easily survived a concentrated beam with nuke like firepower output
btw, this is Gunjack's ending, it begins from 0:30
> 1:07:35 - 1:09:19
Kazuya easily destroys Heihachi's Satellite and the remaining of the destroyed parts also raze a town
> 1:14:25 - 1:18:52
we learn what happened between a younger Heihachi and Kazumi and the reason why Kazuya was thrown from the cliff, also, young Heihachi was able to defeat Majin Kazumi
> 1:21:02 - 1:33:14
the final battle between Kazuya and Heihachi takes place in a large volcanic area with many large rock formations and lava surrounding the area and being visible from the ground too, their battle has a DB like feeling since there are several explosions through the rocks, many powerful hth clashes and etc, at some point, Kazuya transforms into True Devil Kazuya and the battles becomes more intense, Heihachi is fighting with his full power and still inflicts damage and survives against this form of Kazuya's, he was even able to revert Kazuya back into his base form, although, Kazuya uses a powerful filled with anger punch attack, he defeats Heihachi and throws Heihachi into the lava as well
we see in the ending, that Jin is the one who can only fight Kazuya at this point, as Jin said, there is no else, it's all up to him and he is ready to kill Kazuya and it is a hint for a Tekken 8 game, probably
in the special ending, which takes place after the Heihachi battle, Akuma appears and is ready to have a final rematch with Kazuya, Kazuya dodges a Hadouken without looking and transforms into a powered up True Majin Kazuya, then their battle begins without seeing the outcome of their battle, in the end
although
we must wait in case they reveal the full outcome of the True Majin Kazuya vs Akuma battle in a DLC or something, because they collided their energy based attacks and it seems they kinda fully razed the large volcanic rocky area where the final battle took place
only time will tell though
