Naruto: Armament Haki Wood Release, Shattering Konoha With One Punch

He transmigrates to Konoha in the year 52 and becomes the last surviving descendant of the Senju Clan: Senju Quanmi.

He awakens a Low-Profile System and immediately fuses with the template of Garp from One Piece.

As he watches Danzō eye him hungrily and the Third Hokage go on about the "Will of Fire," Quanmi gives a cold laugh, smashes the Hokage Rock with one punch, and defects in the opposite direction!

Two years later.

When Quanmi stands before Konoha's gates again, the entire Shinobi World trembles beneath his fists.

Tsunade: "Why is his Wood Release even tougher than Grandpa's?"

Madara Uchiha: "This makes no sense! Why isn't his Sage Art: Wood Release: True Several Thousand Hands using ninjutsu? He's just pounding everyone with his fists!"

Quanmi clenches his fist, wrapped in Armament Haki, and smiles faintly.

"Left fist: high damage. Right fist: pure true damage. Which one will it be, old-timers?"
