Did Kishimoto even plan Tobi to be Obito

[Yatori]

Yup i think this is planned out since beginning.

Obito was a member not spiral zetsu who is inside Obito , spiral zetsu was the one who asked, get your facts straight

 

[RasenUchihaChaos]

Uh obito wasn't even created first when naruto first came out

 

[Honord Sage]

Its a silly question, History id full of people pretending to be someone else to gain something.

 

[synkross]

just a little trivia but the very 1st chapter where Obito appears is named "Who are you" ch:16
