Tanjiro would win, because Deku have no way of killing Tanjiro. Deku may be stronger but in the end Tanjiro would win by stamina or landing a hit at Deku, which have poison that would kill Deku.
In the manga [Spoilers], Tanjiro is easily powerful enough to defeat the 3rd Uppermoon Demon all by himself and has already surpassed the level of Pillars. But Deku is also no weakling. He can use 20 percent of the world's strongest hero's power and can improve himself in the middle of the fight.
Deku Will beat most versions of Tanjiro except Demon King Tanjiro on where Deku can lose by losing Stamina. Demon King Tanjiro cannot be killed. He is immune to sun and mere punches would not kill him.
No. Deku would need the color changing sword to defeat demons even with his quirk. Also if he doesn't have time to strategize then he'd lose to a demon. (In the most recent chapters of the manga he was overcome by a group of people and couldn't escape because he didn't have time to strategize.)
Muichiro Tokito – Mist Hashira
In direct combat, he easily overpowered our protagonist Tanjiro so his strength is not to be taken lightly. Another testament to his skills is his win over Gyokko, an Upper Rank Five demon, whom he defeated all by himself – too with ease.
He also possesses a strong sensory perception as he is able to sense the presence of demons. Tanjiro's superhuman strength gives him the ability to overpower his enemies and dodge attacks at immense speeds, he is able to maneuver and jump easily over large buildings and distances thanks to his amazing strength.
Three Hashiras Tanjiro could beat in Demon Slayer
Comparing an end-of-story Tanjiro to an end-of-story Muichiro, Tanjiro likely takes the win home 99 times out of 100.
Izuku Midoriya is among the strongest characters in My Hero Academia, but there are some who still manage to outclass him. The protagonist of the My Hero Academia anime and manga series, Izuku Midoriya naturally ranks among the strongest characters in the story.
A lot about One For All doesn't make a lot of sense, though. Goku's power level at the first rank of Super Saiyan blows Deku's cowling away already granting Goku about 5o times his base power and with no real risk to Goku's body.
slow ?! , Deku was able to dodge and hit in a split second. And yet he is clearly faster than Zenitsu .
1 Winner: Eren
Unless Midoriya figures out Eren's weakness and hit him with 100% One For All in the nape. Once Midoriya gets exhausted and slow. He'll use One For All at 100% desperately and ends up immobile. Eren can either stomp on him or made him surrender.
Conclusion. Naruto outperforms Tanjiro in every aspect of fighting. He is faster, and his destructive abilities cannot even be compared to the likes of Tanjiro. While the latter might be a skilled swordsman, he doesn't stand a chance against Naruto, who can use advanced ninjutsu techniques in the blink of an eye.
Demon Tanjiro will eat Bakugo alive. Literally. He was more powerful than Muzan by himself in Demon form. Bakugo is fodder.
Muzan wins with Mid-High Difficulty. Muzans strength: Quick Regeneration , Has Shapeshifting, Blood Demon Art and can poison people and can possess people with his blood and can absorb people , also has Supernatural Physical prowess and Mental Prowess and his whips which can give him range.
Bakugo was stronger than Midoriya, though he indicated that Midoriya could eventually surpass him.
Unlike many other answers, Deku at 100% is closer to Naruto than people think. But Naruto still wrecks him. Death Battle did a fight between Might Guy and All Might, with Guy having to open the eighth gate to beat All Might at his prime. In a brute force match up (hand to hand combat) Deku would put up a good fight.
Deku's final quirk is known as 'gearshift'. It's a quirk that is activated via physical contact. It allows the user to change the velocity of anything they touch, meaning they can spontaneously slow things down, or speed things up.
According to this study, that means Izuku was traveling at a rate of 17, 045 miles per hour. That kind of figure makes him eight times faster than the world's quickest jet, and he would be moving at about 10x the speed of a bullet.
1 BEAT: Joker
That being said, while the Joker can often cause issues with his whacky capers, he wouldn't last long in a straight-up fistfight against Deku.
Gentle Criminal may not seem threatening for a My Hero Academia villain. However, during the School Festival arc, he gave Deku a very challenging fight. To put it into perspective, Deku even told Gentle Criminal that he was the hardest villain he has fought so far.
The Thirteenth Form of the Sun Breathing Style is unique in the sense that it doesn't really have a name of its own. Rather, it's a combination of all the twelve forms present in this style, used in succession to maximize their power. This move was devised by Tanjiro solely to defeat Muzan.
Obanai hated Tanjiro with a passion, even more than he hated Giyu. It started with Tanjiro's breach of Demon Slayer conduct and insubordination during the Hashira meeting, but intensified after Tanjiro interacted with Mitsuri during the Swordsmith Village attack and completed her Hashira Training with raving reviews.
Shinobu Kocho is a capable Demon Slayer whose worthy of being the Insect Hashira. That being said, she's arguably the weakest Hashira when it comes to pure strength.
