Nope, he is immune to certain attacks such as bullets, but it has been shown early on in the series, that people with enough strength can infact hurt him just by punching, without using Haki.
Due to his rubber body, Monkey D. Luffy (One Piece) is immune to blunt force attacks.
of 1.000 s, the blow would be equivalent to 13.828 kN of force exerted on the target. Given that the punch force of an elite heavyweight boxer is approximately 5.000 kN [8], the power behind Luffy's punch is 2.766 times greater.
Luffy explicitly is resilient to bludgeoning force, but he can be hurt by it. In fact, the entire Lucci fight until he goes jaguar form is practically disproving the "Luffy immune to blunt force" theory, since Luffy gets demonstrably injured and tired.
1 Luffy: Impulsiveness
His greatest flaw is his impulsiveness.
One of his more decisive defeats came in Alabasta when he fought Crocodile. He was unable to get past the former Warlord's Logia powers and after 3 minutes, Crocodile simply impaled him with his hook. Crocodile left Luffy with a critical injury and tossed him into quicksand to ensure his demise.
Despite being one of the stronger entrants on this list, the One Punch Man one-off antagonist still certainly loses to One Piece's Luffy in a matchup. Like other House of Evolution members, he's simply very low on the series' ladder of power creep, swiftly becoming irrelevant by the time bigger players are introduced.
Luffy's greatest feat of strength (so far) is seen in the Water 7 Arc, when he is trapped between two enormous buildings and escapes by pushing them apart. It also shows how strong he can get at times. Luffy also possesses great endurance and reflexes to match his strength and speed.
When he was a child, he was afraid when Garp would find out about his dreams of sailing as a pirate. He is wary of Nami's temper, as he thought whoever wanted to marry her is brave.
Weaknesses. Despite these advantages Luffy is not immortal. Though immune to lightning, he can be damaged by other elements such as fire or ice, attacks involving cutting or stabbing and Haki-infused attacks.
Reminder that Luffy is immune to water attacks since he can just turn it into rubber with Gear 5. While we only have a few examples of them(Doffy/Kata/Luffy) We have never seen anyone use an awakened power to turn the water before.
Luffy can turn anything around him into rubber and this includes the forces of nature as well. When in the skies, Luffy can give the properties of rubber to a raging thunderstorm and control lightning as he wishes.
In the fight against Kaido, Luffy finally tapped into what is his strongest transformation of all time and supposedly him at his peak – Gear 5.
The longest fight in #anime history goes to One Piece. The Luffy vs. Katakuri fight lasts for 21 episodes.
Bearing in mind Saitama's feats, Luffy's Gear 5th stands absolutely zero chance against him.
1) Zeno. As the Omni-King of Dragon Ball's multiverse, Zeno and his powers of erasure overall existence give him an easy out in a fight against One Piece's protagonist. As powerful and determined as Luffy is, there's simply nothing he can do against a power that stands above the laws of nature.
Nope. If compared to real life, how strong are Luffy's punches, one from each gear?
Love that the manga clearly states Luffy (the gum gum fruit) has a weakness to sharp objects/cutting attacks, but we're STILL having this debate.
Speaking of the novelty of exploring – our protagonist Luffy has a pretty unique way of moving around the map. His power allows him to stretch, expand and change his body in some interesting ways. He can latch on to ledges quite some distance away and pull himself up onto them, and he also doesn't take fall damage.
Luffy's first proper defeat in One Piece came at the hands of Smoker, who served as a Marine Captain back during the Logue Town arc. Being a Logia type made of smoke, it was impossible for Luffy to beat Smoker. The battle between the two wrapped up quite quickly and ended in favor of Smoker.
In addition to this, Luffy is afforded the enhancements common among Zoan Devil Fruits, including greater strength, speed, and a faster recovery rate. He also displayed the ability to bestow the properties of rubber into the environment around him.
