While Shanks' combat skills are seen very sparingly throughout One Piece, there's little to no doubt he's stronger than Luffy and could defeat the Supernova.
Shanks is one of the Four Emperors of the Sea and certainly the strongest in their ranks right now. He possesses a bounty of over 4 billion berries right now, which is certainly the highest active pirate bounty that the fans know of. Shanks does not possess any Devil Fruit power, unlike Luffy.
Gojo Satoru's biggest asset is his mastery of cursed energy. He can use techniques such as Limitless, Infinity, and Unlimited Void. His Hollow Technique: Purple is a special ability that can erase all kinds of matter in its path. Gojo Satoru can use this technique to easily take down Luffy.
The fight is, undoubtedly, the most difficult one that Luffy has fought so far. Kaido managed to defeat Luffy three times. For the first time, Luffy faced defeat against him Kuri and was thrown in prison. There, he learned Internal Destruction Ryuo and took Kaido on during the Onigashima Raid.
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.
Fan theory suggests that Luffy will awaken Gear 6 in One Piece. The concept of Gears was introduced in the Enies Lobby arc of One Piece when Luffy brought out Gear 2 against the CP9 agent Blueno. His skin turned pinkish and heated up, allowing our main character to move faster.
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.
It is evident that the only person capable of surpassing Roger is Luffy. Even though Luffy still has a lot to achieve, he is the only person who can transform the entire world.
Nami was one of the first characters to join the Straw Hat Pirates, and remains an extremely important character to the story. When it comes to strength, she's the weakest member of the crew, which is why she often relies on clever tricks and strategies in battle.
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.
1) Kaido. Kaido did in fact lose to Luffy's Gear 5 at the end of the Wano Country arc. However, keep in mind that he withstood multiple waves of strong enemies before this final encounter. Luffy was also completely worn out after the fight and fell into a coma for about a week.
Points: Zoro 1, Law 0 Devil Fruit Roronoa Zoro is a very powerful character. He is known as one of the most powerful characters in the series and one of the series' best swordsmen; he is, by all means, probably going to surpass even Mihawk in the future.
Not only he is believed to be the strongest Warlord, but he could be on the same tier as Shanks. My guess is that Luffy might never be able to beat Mihawk as he is the greatest swordsman in the world. We can see Luffy running away from Mihawk's sword swings as he knows he would get cut, during the 'War of the best'.
Luffy will only become the Pirate King if he gets his hands on the legendary treasure, and for that, he has to reach Laugh Tale.
The only character confirmed to have the power of a god is none other than the series' protagonist, Monkey D. Luffy. Having awakened his Devil Fruit after seemingly dying at the end of his battle with Kaido, Luffy discovered that his powers were actually that of the Hito Hito no Mi Model: Sun God Nika.
Because of this, “touch of death” Devil Fruits such as the Hobi-Hobi No Mi are an awful matchup for him. All it takes is one touch against any of his stretched-out limbs and Luffy becomes a toy without any way to fight back and no one to remember him.
"Iron Mace" Alvida is the former captain of the Alvida Pirates and the first antagonist encountered by Luffy on his journey after going to sea.
The strongest form of Luffy's Gear 4 is Bounceman. This technique debuted during Luffy's fight with Doflamingo and, since then, has become his go-to Gear 4 form.
However, Luffy's Gear 5 allows him to expand to the size of a real giant. Since his body is proportionately massive, he can use his usual techniques with much more strength behind them.
