tobirama feats include.
getting pawned by an old man
hmm.... I can see that you don't think much of the 2nd. Well Edo Tensei fight with hiruzen doesn't count. Take for example Kabuto stated that he has surpassed Oro in his use of Edo, yet some of his high teir edo's got taken out pretty easy, i.e. nagato. When it is someone else controlling the person it really can't be considered them fighting. So to say Tobirama got pawned by the 3rd doesn't really count. Instead it essentially saying Oro didn't or couldn't utilise the technique well enough to ensure victory.
On to his feats
1. He obviously mastered Edo (in his time period) since madara stated that the 2nd's technique was originally designed to wipe the battle field clean, therefore he must have been pretty effective at it.
2. Yes, we don't know how well he uses S/T, but come on.. Minato has FTG, Tobi has the dimensional S/T thing. S/T seems to revolve around one select (or base) technique, so if he has one then we can assume he was decent at it, why else would minato mention him when commenting on Tobi's S/T technique.
3. Has been named the best water jutsu user ever.
4. Took on 20 or so ninja alone (which include the kin-gin Bro's) to let his comrades escape, and they did so he must have bought them a reasonable amount of time, and thus held his own for a while.
5. He was the 2nd Hokage
Compared to the above I don't see what Kakashi has that can compare. :shrug:
He used himself and the 2nd as far as setting the bar goes. Why would he mention the 2nd if he wasn't one of the greatest users of it? Why not just mention himself? He said it like Tobi surpassing him and the 2nd was an achievement and a feat...and that's because it was.
I completely agree with this
