He should have died
He will die anycase
He doesn't deserve to die
His performance was amazing
I expected more from him
If Gai was seriously a threat to madara, he would've reacted against him like he is reacting now against naruto. He was surprised that Gai managed to deal so much damage but I wouldn't call that worried.
It is really funny, even in the weaker jutsu, Evening Elephant, Madara could not react, so obviously Night Gai/Moth is way faster and stronger, Madara could react even less than nothing... but ok
Madara states that Gai almost killed him (in one of the translations he was lucky to survive), but let's just deny it because... no there is no reason to =)
Naruto saving Gai - Whoever saw this coming?
