Most Versatile Ninja Ever

[General Lex]

Hiruzen was considered a master in all the basic forms. Born with no known KG, while becoming strong enough for the hokage position (longest sitting lager seen thus far). Although we have not seen his abilities ima give him the benefit of the doubt and believe that, at least, he is the most versatile ninja (relied solely on the basics).

 

[uchihajaime]

Kakashi, Itachi, or pre-Sussano Sasuke

 

[Dark Artist]

Madara then Sasuke

 

[Tera Path]

Jiraiya solos.
He seals, he summons, he has Sennin mode. He throws kunai, he uses elemental jutsu.
He was the most fun to watch.

Not to mention he has great entries

 

[Tobi123]

Itachi & Jiraya

 

[Wik]

Itachi based on feats then Kakashi

Everyone should acknowledge Itachi as thevclear winner but since he the most hated on ninja ofcourse they wont

What planet are you living on?

OT:It's hard to say who is THE best but these are definately up there. Kakashi, Itachi, Sasuke, Orochimaru and jiraya all are not really bad at anything.

 

[EternalFlame]

Not sure about ever, but Sasuke has a pretty versatile moveset.

Close, mid and long-range Ninjutsu.
Nature Jutsu
Very adept taijutsu
Skilled in Kenjutsu
Good at Genjutsu
Very fast hand-seals
Master at shrikens and kunai throwing
Very fast movement speed
Many one-shot attacks
Flight via hawk summon
Ground summon, snake
Very strong defense, Susanno
Ridiculously OP Susanno sword
Some kind of sensing

What he lacks is self-healing and barrier jutsu.
