A question about Naruto character

[Ansatsuken]

I want to ask one question about one Naruto character. This character keep playing in my mind time to time and his name is Uchiha Madatachi. Is he a filler character from Naruto anime? I remember someone posted a picture but couldnt find it for a reference.

He's Itachi's split personailty.

Madatachi? You sure it's not from some Madara x Itachi fan fiction? I've never come across it, and google doesn't give much of an indication either.​

I heard that that was Itachi’s ideal self-image to which he could never achieve.

madatachi uchiha is sasuke's second child which is from a fanfiction. it is not cannon at all.
