Would you guys like to see a Spin Off series of Kakashi's days in the Anbu? They coud make it very covert and all and have the focus be Kakashi gaining his fame. I think it would be really cool and would develop Kakashi's past in a more positive side.
The Sannin
Prime Hiruzen
Hashirama and Mikoto, including their children and how Hash died.
Minato and team
Bit more history on the clans, Uzumaki and Juugo's and others
And more stuff that will never happen.
Oh Right lol when I do watch the Anime I skip past the filler so I forgot.
I do like the sound of Jiraiya and his team in a spin off or even an Itachi spin off with Izuna
