@No:
Almost got me there Gep 
But we all know Natsu has plotz in his ass reserve . You know , the place he retrieves victory from every arc ?
Plus , plot dictates he must advance for Hiro to focus on in the next rounds .
You forgot the order of the arc, the first fight natsu has is undetermined, he can either win, lose or tie. I don't think he'll win through brute force if anything gildartz will let him pass admiring him of his courage or something like that.
You were thinking of the big bad fight. That's where natsu get's his one time only power up.
@Azureknight76:
Judging by charles vision natsu is gonna win
Honestly that doesn't prove anything cause we don't know when that event happens
@Hekti:
Agree on that.
Thanks to Gajeel the anime is way better
Gajeel makes everything better
and as for the new episode, I don't like how wendy was thrown into it also Ichiyama looks weird animated.
