Do you guys think Hashirama could have learned Sage Mode on his own? He doesn't seem to have any kind of animal summoning not animal characteristics in his Sage Mode. Being the skilled shinobi he is, do you think Hashirama might have learned to take in natural energy by himself, and learn how to balance natural and his own chakra by himself?
I think it's possible. He might have just learned about nature energy and practiced the method himself the somehow.
