Monkey D. Luffy is the main character of the anime and manga series One Piece, created by Eiichiro Oda. He is known for his cheerful personality, his love for adventure, and his ability to stretch his body like rubber, which he gained after eating the Gum-Gum Fruit. However, Luffy’s true strength lies in his ability to use a unique fighting style known as “Gear” to enhance his physical abilities and increase his combat effectiveness. The first Gear technique he learned was Gear 2, but before that, he had to learn Gear 1.
Luffy first encountered the idea of Gear during his battle with the powerful Marine Captain, Smoker, in the Loguetown arc. Smoker was able to easily overpower Luffy due to his Devil Fruit ability, which allowed him to turn his body into smoke and avoid Luffy’s attacks. Luffy was desperate to find a way to defeat Smoker and save his friend, Zoro, who had been captured by the Marines.
During their battle, Luffy noticed that Smoker’s Jitte, a type of Japanese weapon used by law enforcement, had a unique ability. By compressing his smoke into the Jitte and then releasing it, Smoker was able to increase the weapon’s power and speed. Luffy was fascinated by this technique and realized that he could use a similar method to enhance his own physical abilities.
After the battle, Luffy spent some time experimenting with different ways to compress his rubber body. He eventually discovered that by inhaling a large amount of air into his lungs and then using his rubber body to compress it, he could increase his strength and speed dramatically. However, the technique had a serious drawback: it put a tremendous strain on his body and caused him to lose stamina quickly.
Luffy first used this technique during his battle with Don Krieg, the leader of the pirate crew that attacked the Baratie restaurant. Krieg was a formidable opponent, but Luffy was able to use Gear 1 to match his strength and overwhelm him in combat. However, Luffy was still unable to defeat Krieg completely and had to rely on the help of Sanji and the other chefs to finish the battle.
After the battle, Luffy realized that he needed to find a way to use Gear 1 without putting so much strain on his body. He began training his body to withstand the stress of the technique and eventually learned to use it more efficiently. However, he also knew that he needed to find more powerful Gear techniques to keep up with his ever-stronger opponents.
In the Water 7 arc, Luffy encountered the genius inventor Franky, who had developed a new type of fuel called “Coup de Burst” that could be used to increase the speed of ships. Luffy was intrigued by the idea and asked Franky if he could use the same principle to increase his own speed. Franky agreed to help Luffy and developed a new Gear technique called Gear 2.
Gear 2 allowed Luffy to use his rubber body to pump blood faster and increase his speed and strength even more than Gear 1. However, the technique also put an even greater strain on his body and caused him to lose stamina even faster. To counteract this, Luffy developed another Gear technique called Gear 3, which allowed him to increase his size and strength by inflating his bones with air.
Overall, Luffy learned Gear 1 during his battle with Smoker in the Loguetown arc. He developed the technique by compressing air into his rubber body, which allowed him to increase his strength and speed dramatically. However, the technique also put a great strain on his body and caused him to lose stamina quickly. Luffy eventually learned to use Gear 1 more efficiently and developed even more powerful.
