Gai first evening elephant could have put madara near death and of gai had naruto sage mode his power and speed everything would have been increased dramatically.

Lol no. Kaguya is still way above Gai.

I don't think so. Even Naruto was having hard time and he had the Bijuu and Sasuke.

[Bolt Rules]

Yata GG but okay
