Who can activate jutsu the fastest? ( Not Kakashi ) 

Shishui not faster than Raikage A

Agreed 100 percent

Do you need any hand sign for the rasengan ?

@@bronny0411 i guess no but still it's only one jutsu hashirama perform every jutsu with one sign

@@AnnuSharma-yb4kragain he can do it without weaving a single one and also yes rasengan doesn’t need signs but it’s only because it’s based off a tailed beast bomb and when have you seen gyuki kurama use hand seals for tailed beast bomb

@KingMidas420 1) I am just saying he(characters like naruto) can do one jutsu without weaving hand sign 2) Hashirama can heal his wounds without using healing jutsu hand sign 3) In addition Hashirama can perform all jutsu he knew with one hand sign

Orochimaru made around 3 hand signs before performing windstyle jutsu against Victor. It took around 1 sec for that. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8oO4RrF0u6M.htmlsi=W6qCXXJrxU4KqTD0&t=112

Even if Hashirama didn’t need hand signs, the question is, ‘Who can activate jutsu the fastest?’ Hashirama may still take some time for jutsu activation, even without performing hand signs. On the other hand, Minato’s jutsu activation is instantaneous.

That's for sure!
