The movie was set 2 years after the events of FF7, Tifa had been living in peace for that time and was most likely out of practice. How I interpret the games is that because of their near constant fighting, their skills and bodies were honed to an almost deity-like degree. Without the pressure of constant life or death struggles it's no surprise that Tifa's fighting prowess would deteriorate substantially. Therefore, Tifa's combat ability as of Advent Children is not a good representation of her combat ability during the fight with Sephiroth.Kolby Jack said:My god, the logic hoops you're jumping through to try and win this argument are amazing. You're now applying a set of logic from one non-canon source to justify the logic in the game. That's just pure denial, right there. Especially since you ignored my point that Tifa, CANONICALLY, was beaten in a fist fight by Loz (though I got his name wrong in my previous post). So I guess in the Final Fantasy 7 universe, Loz's punches, which knocked Tifa out, are stronger than the sun exploding. Or that any attack in the game capable of knocking her out is stronger than the sun exploding. Man, why did anyone fear meteor doing paltry massive destruction to the planet? Why did Sephiroth even bother with it when he could just explode the sun, several times? Do you see the insanity you're trying to pass off as proof yet? At this point if you can't, I can't help you, but I would recommend maybe some kind of medication, or therapy.
Not that I'm saying that Sephiroth's supernova attack literally destroys the solar system, it's pretty clear that the solar system still exists afterwards.
Edit: Also the movie sucked anyway.
