Yeah but Oro and Obito(with the kyuubi) ambushed the Kage's and both Oro and Tobi are miles ahead of Kinkaku/Ginkaku which would justify Hiruzen and Minato dying. But if the 2nd was as powerful as Hiruzen, then even if they ambushed him(not he also had the 2nd raikage to help) then they would have still defeated them.
Weakest kage.
He got left on the brink of death by Kin/Gin bros (stayed alive due to senju DNA)
and then lost to 20 fodders
dude tobirama is so underrated just because we have not seen him fighting, i hope kishimoto either shows a flashback or have sasuke and orochimaru revive the hokages with that scroll from the death reapers stomach temporary so we can see them fight ... maybe fight madara and obito
He has to be strong.
-He was the 2nd Hokage and kept the Uchiha in check
-He was the 2nd strongest Senju
-As far as we know he was the first ninja to use S/T Jutsu
-He created Edo Tensei
I mean come on it only makes sense he is poowerful
