How does one read the series, see Hashirama be helpless against Juubito and then think "I bet this man could give Kaguya Otsutsuki a hard time"?
And after Sasuke, who had previously fought not only Juubito but Juubidara, questioned how it was 'even possible' for anyone to have that much chakra when he saw Kaguya.
Madara is here too.
And?? What is he suppose to do here without his Rikudou powers? Kaguya just one shots them both
Madara drops a meteor on her and then slashes her with Kanseitai Susanoo. Hashirama summons Flowering Forest to put her to sleep and then he fists her with his wooden golem. Eighty Gods Vacuum Palm is countered by Shinsuusenju. If she uses Infinite Tsukuyomi then Madara wakes them up. The Murderous Ash Bones are tanked or regenerated from. Bringer of Darkness blinds her and Madara puts her under Genjutsu. If she uses the Expansive Truth-Seeking Orb then Hashirama finger flicks it back at her.
