In his base form, Naruto is immensely strong. However, when he combines his Six Paths Sage Mode and his Kurama Mode, he is stronger than anything Luffy will ever face. Even if Luffy were to get 10 more Gears, he still wouldn't be strong enough to stand up to Naruto in this mode.
It depends on how quick the fight will last. Luffy's Gears are costly and can't be maintained for long stretches of time and neither can Baryon Mode for Naruto. Due to the number of drawbacks the Baryon Mode brings, Luffy will probably clinch victory in Naruto vs. Luffy if they break those modes out.
He can now use an advanced form of Conqueror's Haki to infuse his swords with great power, but even this ability cannot beat Naruto. Sage Mode would make landing a sword strike very difficult, and it is hard to believe that Zoro would be able to cut through Naruto's Tailed Beast Mode.
4) Blackbeard. Blackbeard is the first One Piece character on this list to not be confirmed to have Conqueror's Haki. Nevertheless, his Devil Fruit powers and cunning are more than enough to secure him a near-instantaneous win against Naruto's Akatsuki.
Unfortunately, Luffy's rubber body doesn't make him impervious to fire, so Sasuke is already stronger thanks to his Amaterasu, and his Susanoo's arrows are strong enough to pierce Luffy's body.
Both Naruto and Luffy are very determined fighters that will stop at nothing to defeat their enemies and achieve their ultimate goals. While Luffy is a strong fighter in his own right, his strength is nowhere near the level needed to put Naruto down in a fight.
However, physical blows without Haki don't work on him due to his rubber body, and the only slashing-style ninjutsu Sakura is shown to know is a scalpel-like blade. With that being her only weapon to hurt Luffy with, it's likely she will lose this fight in embarrassing fashion.
Goku is one of the strongest characters not just in Dragon Ball, but within the entire anime world. Luffy's biggest mistake would be to get on the wrong side of Goku. There isn't any competition and even if Luffy got over a hundred attempts to beat Goku, he would still be unsuccessful.
Conis and the rest of Skypiea witnessed Luffy completely destabilize Enel's attack. She then witnessed Luffy finally defeat Enel by punching the god straight into the golden bell.
In his base form, Naruto is immensely strong. However, when he combines his Six Paths Sage Mode and his Kurama Mode, he is stronger than anything Luffy will ever face. Even if Luffy were to get 10 more Gears, he still wouldn't be strong enough to stand up to Naruto in this mode.
Sadly enough, Zoro would have trouble fighting Naruto's most powerful Uchiha due to the Sharingan. Madara would avoid Zoro's attacks without even breaking a sweat, ending the fight only with a few hits.
In terms of raw speed, Naruto may have the edge over Luffy. His Body Flicker technique has been shown to be incredibly fast, and he has used it to outrun opponents and move quickly through battles. However, Luffy's speed should not be underestimated.
Goku is already a master of many abilities and operates at a much higher level than Luffy at his most powerful. While Luffy's Gear Fifth abilities are indeed impressive, they are not equal to Son Goku's mastery.
As such, Luffy awakened the true abilities of the Nika fruit. With its powers, Luffy was able to topple even Kaido and if he could defeat the man who was the Strongest Creature Alive, he can certainly defeat Shanks as well.
No. While Gear 5 Luffy and Luffy in general in powerful, he can't deal with someone like Madara. Madara has better attacks, better defense, and more had so yeah.
Over the years, he's faced adversity in many forms and overcome them with his many power-ups. Currently, Luffy is strong enough to fight the strongest of the Yonko in a one-on-one battle, making him extremely capable.
Luffy is a lot more enduring and a lot more heavy hitting than Kakashi in his current form without Sharingan. Even the strongest form of electricity such as Raikiri will be ineffective. Through Haki and Rubber: Luffy wins.
Naruto wouldn't even need to enter Kurama Mode, his strongest form, for Luffy to be entirely out-gunned. Naruto is so absurdly powerful that, when working alongside Sasuke, the two shinobi have enough raw power to demolish an entire continent.
LUFFY HAS ARMAMENT HAKI - This allows luffy to turn his body into a near enough indestructible material, this is not only amazing as a defensive strategy against naruto, but is also an incredible offensive feat that actually would be a suitable match for narutos defence (including kurama)
Mortician: Sasuke was also way faster, Zoro was fast enough to keep with the teleporting Former King of Sorbet Bartholomew Kuma.
Naruto is probably smarter, and definitely faster. Luffy is stronger.
Luffy has the power of Gum-Gum fruit, making him a rubber man. He uses his ability quite creatively and has mastered all 3 forms of Haki. In a fight against Itachi, the current Luffy in his Gear Four is in a totally different class from Itachi. This Fight will be an easy win for Luffy.
