Naruto: The Armored Brawler

Other people transmigrate into the Naruto world: they never have enough chakra, are a beat slow forming hand seals for ninjutsu, and think about escape routes first when enemies appear. When I transmigrated into the Naruto world: I got struck by lightning and dropped into Konoha from the start. Both my parents were dead, so I was an orphan from day one. I thought I'd have to scrape together money to buy soldier pills, but after waking up one day, I awakened LOL's Sett template! The Secret Art of Lightning makes my fists crackle with electricity, and the Secret Art of Earth makes my arms hard enough to smash kunai. The most ridiculous thing is this “Grit” meter. Other people lose health when they get hit, but the harder I get hit, the heavier my punches become. Ninjutsu just tickles when it hits me, and one counterpunch can pound someone into the ground so deep they can't even dig themselves out. Naruto chases me around every day, yelling, “Big bro, teach me how to fight!” Sasuke originally wanted to test his Sharingan against me, but I knocked him out with one punch. Now he shows up at my door every day to challenge me. Sakura went from thinking my fists were too hard to bringing me meals every day and asking me to teach her how to smash rocks with a single punch. All I wanted was to quietly work as Konoha's hired muscle, but Kakashi said I had the makings of a Hokage, and the old Third Hokage insisted on plopping the Hokage's hat on my head. Later, Ōtsutsuki Isshiki came down from the moon to destroy Konoha, so I charged up my ultimate move, Haymaker, and punched him right back to the moon. While I was at it, I made the surrounding small nations into Konoha's vassal states. Now the entire shinobi world knows that Konoha's Sixth Hokage is a dangerous man you shouldn't cross. After all, nobody wants to find out what it feels like to get punched into the ground by an electrified fist.
