What You'll Learn

Luffy and Grount's first encounter
Luffy first encounters Grount in a cafeteria on Fron Island. Luffy causes an altercation by taking an entire bowl of curry, which leads to Vice Admiral Prodi ordering his men to battle the Straw Hat Crew. Luffy tries to leave the cafeteria, but Grount lunges at him, and the two duel. Luffy gets the better of Grount by slamming a curry ladle into the Marine's face. Grount's comrades, Bonham and Zappa, join the fight, but Luffy manages to avoid their attacks and tries to leave the room. Bonham blocks the exit and attacks Luffy, who activates Gear 2 and blows him away.
Grount unleashes his true power and battles Luffy again. During the final showdown, Grount's left arm is revealed to be covered in red fur and endowed with tremendous strength. Despite this, Luffy manages to overpower Grount, who is left dejected and feeling weak. Grount regains his will to fight after remembering the lessons of Kuzan, a man he met when he was a boy and who saved him by stopping his Devil Fruit powers from going out of control.
Grount ambushes Luffy on the coast, where he has just defeated Bonham and Zappa. Grount exerts his left arm's full power, shattering the metal brace that had been limiting its strength. With full control over his monstrous arm, Grount initially manages to overpower Luffy, but Luffy fights back and activates Gear 3. The two clash evenly, but Luffy ultimately defeats Grount, sending him flying into the ground.

Grount's devil fruit powers
Grount is a character in the anime *One Piece* who possesses a mysterious Devil Fruit power. His ability was created by the anime team in collaboration with Eiichiro Oda, and it bears similarities to the SMILE fruit. Unlike typical Zoan Devil Fruits, Grount's power only affects one part of his body—his left arm—which becomes monstrously large with red fur and claws. This arm grants him tremendous strength, allowing him to unleash powerful blows that create wide-reaching shockwaves. Initially, Grount struggled to control his power, and it is suggested that he may have eaten a Mythic Zoan fruit, specifically the "Ape-Ape fruit: Model - Yeti". This theory explains that Grount's full form is a giant ape-like creature, while his hybrid form is smaller and more elusive, resembling a Yeti.
Grount's Devil Fruit power has a significant impact on his combat abilities. Despite his large and disproportionate arm, Grount retains his speed and agility. He is capable of overwhelming dozens of his fellow Marines in direct combat, showcasing his exceptional fighting skills. Grount's power first manifested when he was a boy, and he was unable to control it, accidentally destroying an entire island town. Admiral Aokiji intervened and froze Grount's arm, preventing further destruction. This incident led Grount to join the Marines, where he received a metallic brace to limit his power and help him gain control. However, he still struggled to master his ability, and during his first encounter with Luffy, he was defeated, causing him to question his strength.
Grount's Devil Fruit power plays a crucial role in his battles, particularly against Luffy. In their initial confrontation, Luffy defeats Grount, causing him to feel frustrated and inadequate. However, with the memory of Admiral Aokiji's advice, Grount regains his fighting spirit and unleashes his true power. He breaks free from his metallic brace, fully revealing his monstrous arm. Grount's arm possesses immense strength, allowing him to clash evenly with Luffy in Gear 3 and create powerful shockwaves with their clashes. Despite Grount's improved control over his power, Luffy ultimately overpowers him, showcasing the intense nature of their battles.
Grount's Devil Fruit power remains a significant aspect of his character, and it sets him apart from other Zoan Devil Fruit users. While he may struggle with controlling his power at times, he continues to improve and harness its full potential. The nature of his power, with its unique appearance and tremendous strength, adds an intriguing layer to Grount's character and combat abilities within the *One Piece* universe.

Luffy's elephant gun
The attack is first seen being used against Kraken and later against All-Hunt Grount, a Marine Captain with a monstrous left arm. Grount's arm is the result of consuming a Zoan Devil Fruit, which caused it to become disproportionately larger than the rest of his body and covered in red fur. Despite his large arm, Grount is still extremely fast and has excellent reflexes, making him a formidable opponent.
In their battle, Luffy initially struggles against Grount and is overpowered in Gear 2. However, Luffy activates Gear 3 and clashes evenly with Grount. Luffy then unleashes his Thor Elephant Gun, causing a tremendous shockwave. Eventually, Luffy manages to overpower Grount and send him flying into the ground, defeating him.
The Thor Elephant Gun is a lightning-enhanced version of Luffy's Gomu Gomu no Elephant Gun technique. The lightning around Luffy's fist is not caused by the attack itself, but by the clash of two Conqueror's Haki users with their Armament Haki. This was first seen in Luffy's fight with Chinjao, where the lightning-enhanced attack accidentally restored his drill-shaped head.
Luffy's attacks often have animal-themed names, and it is speculated that he names his Haki-imbued attacks after the beasts he first needed them against during his training. The "Elephant Gun" name thus likely comes from Luffy needing an elephant gun to take down an elephant during his training.

Grount's inability to control his powers
All-Hunt Grount is a Marine Captain and the main antagonist of the filler Marine Rookie Arc in One Piece. He is a user of an unclassified Zoan Devil Fruit, which grants him tremendous power and great fighting skills. However, Grount initially lacked control over his powers, particularly his left arm, which became monstrously large with red fur and claws upon consuming the fruit. This arm acted on its own volition, attacking anything and anyone close to him.
- Lack of Mastery: Grount may not have achieved a certain level of mastery over his fruit's powers yet. This could be due to the unique nature of his Devil Fruit, which only affects one part of his body (his left arm) rather than his entirety, and the lack of precedent for such a power.
- Accident and Aversion: It is speculated that Grount may have eaten the Devil Fruit by accident and developed an aversion to his powers. As a result, he might have chosen to neglect training and understanding his abilities, opting to suppress them instead.
- Personality Resonance: Grount's personality seems to resonate more with the full form of his powers, which is described as aggressive and violent. This resonance could make it challenging for him to control and balance his abilities, especially if he is afraid of the full extent of his powers and their potential consequences.
- Lack of Training: Some suggest that Grount's inability to control his powers stems from general incompetence, ineptitude, or a lack of adequate training. However, this theory is contradicted by the fact that Grount was a subordinate of Aokiji, who could have provided him with the necessary training.
To manage his powers, Grount was given a metal brace when he joined the Marines. This brace limited the power of his left arm, allowing him to handle it better in combat. However, Grount was still able to exert partial strength, as evidenced by the steam shooting out from the vents in the brace.
