Yeah yeah yeah, he's tough. But guess what fanboys!
DSM Kabuto > Hashirama
Edo Madara with Senju DNA, 7 Swordsman, Itachi, Asuma, Akatsuki, Gin, Kin, 3rd Raikage, Muu, 4th Kazekage, 2nd Mizukage... Need I say more?
DSM Kabuto alone is almost untouchable. With all of HIS power (the summons) on top of his DSM, Hozuki techs, sound techs... Yeah, DSM Kabuto rapes.
Get over it Hashi fanboys! You know who you are
