The greatest scientist (ATM) in narutoverse

[BEASTLY NARUTO]

My opinion;oro
whats yours?

 

[brockleetastesgood]

orochimaru hands down... tobi is second... kabuto is third... actually tobi and kabuto's positions are interchangeable

 

[Red Slayer]

1)Oro
2)Kabuto

 

[Kages]

Orochimaru then Kabuto or Madara or Obito

 

[King Of Sharingan]

oro

 

[Owarij]

Orochimaru,
2nd kabuto probably, he mostly just enhanced on orochimaru's already existing worked

third would be tobirama for the invention of edo tensei, to develop it he would have had to test it on living people/dead people

 

[Dreckerplayer]

ATM he said!

Kabuto is the obvious answer...since Orochi has been hiding inside ankos neck

 

[Narutoga]

Oro

 

[Izuna Kakashi Senju]

Orochimaru or Kabuto.
