Now I know some of you will vote for Hashirama and Tobirama , for the following reasons , whether they have logic or not-
1)Tobirama was the best suiton user of all time , thus Minato and Hiruzen won't stand a chance
2)Hashirama and Tobirama were both highly skilled in combat , with high attributes of Stamina , Speed , Strength and Defence .
3)Hashirama was extremely skilled at Mokuton , and would confuse Minato , not even letting Minato get close to Hashirama.
4)Hashirama and Tobirama made a great team with many combos
5)Hashirama and Tobirama BOTH could use Bringer of Darkness , rendering Minato's FTG useless.
But a number of you will also say that Hiruzen and Minato and win for some reasons -
1)Minato has FTG , and once he gets close to either one of Hashirama or Tobirama , they're dead.
2)FTG is unavoidable , if Hashirama and Tobirama are unaware and are not fast enough
3)Minato is highly skilled in Stamina and Strength and his MAJOR , UNBEATABLE attribute is speed.
4)Hiruzen won't be easy to defeat as he too , is skilled in Strength and Stamina , and he has the ultimate summoning :- Monkey King Enma , which can also turn into a long , powerful staff.
5)Both Minato and Hiruzen can use the Reaper Death Seal/Dead Demon Consuming Seal , which is one of the most powerful , yet risky sealing techniques.
As for myself , I look at the battle from an unprejudiced eye , and I think both teams will have an endless battle , ending up in a draw . Both Teams have their Strengths and Weaknesses and it's all about who is smarter .
Anyways , WHO DO YOU THINK WILL WIN?! Hashirama and Tobirama , or Minato and Hiruzen ? VOTE UP xd
