Since Kishi makes some cool to DBZ once in a while I think Hashirama really resembles Goku. At least, the Goofyness and extreme power. Also he is from the (physically) strongest race just like the Saiyans where. Tobirama in my eyes resembles Vegeta a lot. The way he crosses his arms, shouts at Hashi. Even the ''hmph'' kinda thing when Hashi talked serious to him.
Anyways, reading the comments I saw that someone said that Hashi might be a Monkey-Sage. I also expect something like this now, since the Saiyans are sort of monkeys too.
Would be awesome if he summons some kind of Oozaroo. Or has a final form with a tail or something. Maybe a combination where his hair turns gold also! But that might go to far.
