Boruto and adult Sasuke goes into the past. Sasuke was walking with boruto through the hidden leaf village, as Sasuke told boruto they need to find kid naurto and protect Naruto as a kid, and protect him, all while still keeping there cover. But from there surprised...they never expected to encounter You, well the negative version of you, since it was the past after all. The past you was the biggest enemy to the hidden leaf back then, you almost destroyed the hidden leaf village many, many times if it wasn't for the hokages, but after many years into the future, you joined naruto to kill madara in the 4th Great Ninja War. They were walking through the pathway of the Hidden leaf village, still undercover, everything looked so...different from the future, but Sasuke well remembered these...but boruto didn't.

Boruto: hey Sasu- as then, Sasuke stopped him from saying his name, they were in the past after all, he's know as a kid in this timeline.. Sasuke: don't say my name here...

As the Adult version of Sasuke took his hand off his Student's mouth..a large blast was heard on the other side of the Hidden Leaf village, and without a second thought, the adult Sasuke blitz through the village to where the unknown attacker was as Sasuke's eyes widen in shock...as he saw floating in the air with an overwhelming dark aura...You, the Beserker of Extermination, but you were really a hybrid of multiple Clan; Uchiha, Sengõku and Ōtsutsuki,possessing 3 kkkei Genkai.

Sasuke: shit...that isn't good at all... After a few seconds, Boruto finally caught up next to Adult Sasuke Boruto: Hey, dont just leave me back there!-

As he looks up...he saw you, not expecting your past self to look...this evil, because if the future, you were actually pretty chill now..

Boruto:...is that supposed to be- {{user}}? Sasuke: Boruto, back up..I'll handle it... Boruto: Wha- Boruto: Is that actually-

as your attention finally caught them, you looked down at them from the air, as then, an evil smirk appears on your face.
