Monkey D. Garp

Vice-Admiral Monkey D. Garp is the father of Monkey D. Dragon, the grandfather of Monkey D. Luffy, and the adoptive grandfather of Portgas D. Ace. He is also the commanding officer of the 153rd Branch of the Marines, and the man in charge of both Koby and Helmeppo. He was one of the major figures along with Sengoku and Whitebeard while Gol D. Roger was still alive.

Appearance
Garp is an old man with a broad chest. He is bearded and has a scar on his left eye. Due to the fact that he had appeared in Romance Dawn V.2 with his face, he wore a dog mask when he was first introduced, so fans would not realize he was Luffy's grandfather. When this fact was revealed he discarded the mask, and hasn't been seen wearing it since.

When he was younger, he appeared to have black hair.

Personality
Garp displays an intelligence level that is equivalent to that of Luffy's; however, Garp seems somewhat more absent-minded than his younger grandson. Due to his hot temper, he is unable to accept excuses (and is really poor at creating his own) and at times likes to enforce his point of view on things with his fist.

He also is somewhat an eccentric person with a rather strange approach to things - he'd rather burst through a wall than enter a door on the grounds that its cooler to do so even when he has to fix the hole (which he did). He, like his grandsons, has an extreme fondness for food; in his case, especially donuts.

Garp has shown signs of narcolepsy. He is seen in the Post-Enies Lobby arc randomly falling asleep while punching Luffy. Coincidentally Luffy fell asleep at that very same moment, suggesting that narcolepsy may run in the family. It might, however, just be a psychological trait that Luffy picked up, as Garp's adopted grandson Ace showed signs while at a diner during the Arabasta arc.

Garp also has his own laughter style: he adds either "Bwa" or "Wa" before the haha part.

Crew
His crew and others around him often react with shock or uncertainty when hearing his reactions to things. At times he will say things that are random or seems to be unaware of the true extent of what is going on around him. At the Marine HQ, many of the other Marines are afraid of him for his reputation and habit of controlling things through his fists.

He is also the mentor of Koby and Helmeppo, he keeps them out of trouble and ensures they are not slacking off. If they do get out of hand, he knocks them around to ensure they keep in place. They both come to admire him, even though he maintains a highly brutal clutch on them because they wouldn't be where they are without him.

Sengoku
As a hero of the marines, Garp has the high respect amongst the marines, even with Fleet Admiral Sengoku. However, currently, as with the revelation that both Monkey D. Luffy and Portgas D. Ace are Garp's grandsons (Ace being adopted), as well as Luffy's multiple actions in such a short time, Sengoku is losing patience with Garp. Garp, on the other hand, seems to merely laugh it off and enjoys getting on Sengoku's nerves. Notably, Sengoku's biggest annoyance is Garp's refusal to keep his family under control even with threatened with the consequences; Garp simply does not believe the life of an old man could ever atone for the actions of his family.

When or how long Sengoku knew of Garp adopting Ace is unknown, but Sengoku found out that Ace is the son of Gol D. Roger. How this would affect Garp's standings in the Marines is yet to be seen.

Monkey D. Dragon
Dragon is Garp's son. No direct interactions have been shown, however, he seems casual about the idea of his own son being a revolutionary and wanted by the World Government. They also seem to be contact with one another as Dragon told Garp that he saw Luffy off in Loguetown.

Monkey D. Luffy
He seems to hold high standards for his grandson Luffy and gets mad at the slightest mistake he does even when his own are sometimes no better (i.e. telling off Luffy for falling asleep yet falling asleep himself). Even when Luffy was too casual in saying goodbye to Garp at Water 7, Garp was disappointed by a lack of emotion after the two were separated for a long time. This often leads Luffy to be at the other end of Garp's punches and due to this experience he has become afraid of him. Garp also claims Luffy was poisoned by Shanks and his influence, as Garp wanted Luffy to be a great Marine like him. However Luffy claims he told Garp even as a child he wanted to be a pirate. Nevertheless the two get along quite well.

As Nami stated at the time of Garp's departure, there seems to be an amazing ego that runs in Garp's family.

Portgas D. Ace
Garp adopted Ace from Gol D. Roger, who requested Ace does not deserve to be treated as a criminal just because of his family ties. At first thinking of adopting Ace was preposterous idea, Garp eventually agreed to Roger's final wish, as the latter pointed out that after countless confrontations, he trusted the Vice-Admiral much as a friend. indeed, Garp seemed troubled when Ace was about to face death.

As well as Luffy, Garp had high expectations for Ace to be a strong Marine, but is disappointed that he chose the life of piracy, which incidentally sent him to Impel Down where they were talking about the issue. However, Ace refused the idea that he and his younger brother could have ever been Marines, with their fathers' restless blood in their veins.

Gol D. Roger
Back when Gol D. Roger, the great Pirate King, was active, Garp managed to corner him many times. As such, they have a long history against each other. However, when Roger was about to be executed, after turning himself in due to his terminal illness, he made a final request to Garp. He asked Garp to take care of his unborn child, as it didn't deserve to be condemned as a criminal because of his father's crimes.

Due to their countless clashes, Roger came to see Garp as much of a friend as the rest of his crew.

Other
No wife has been named for Garp, however the supplement Grand Line Times left a "?" in place of one. Also as a person carrying the Will of D, he may be related somehow to others also carrying it.

Abilities and Powers
Although lacking youth, Garp is an incredibly physically strong person even in his old age. He is able to throw iron cannon balls as if they were baseballs and yet still exhibit a cannon-like effect at the point of impact, break through brick walls and cannon stands with his fists, and carry and throw a gigantic ball and chain many times bigger than the Thousand Sunny. Garp also has monstrous punches at his disposal. Also, his epithet, "Garp the Fist" vouches for his punch strength. In addition to his legendary strength, he has extreme endurance and stamina, as he was slashed by Captain Morgan's axe hand and able to recover seconds later with no obvious pain and even being oblivious to the fact he was struck. He has also shown inhuman speed, as he managed to bypass all of the Straw Hats and Franky (who still wasn't a Straw Hat at that time) in order to get to a sleeping Luffy and he appeared as a blur while doing so. He's also a "hero" of the marines and is known for cornering and fighting Gold Roger many times. Whitebeard seems to respect Garp's strength as he mentioned him during his talk with Shanks.

Weapons
So far he's been seen throwing cannonballs (including a giant one, mounted on a chain) with his bare hands. The cannonballs he threw went faster than a cannon would fire them due to Garp's strength. An interesting fact is that Garp is the only person with the initial D. to use materialistic weapons.

Attack List

 * Fist of Love (愛の拳, Ai no Kobushi): A simple but powerful punch to Luffy's head, where it was strong enough to hurt the rubber man. It is a gag technique to show his "love" for his grandson, and has a comedic effect.
 * Iron Fist Meteor (拳・骨・隕石, Gen Kotsu Meteo): Garp throws a cannonball at an enemy ship. Due to Garp's Super-Human Strength, he can throw them like baseballs, yet they are more powerful than being fired from an actual cannon.
 * Iron Fist Meteor Shower (拳骨流星群, Genkotsu Ryūseigun): Garp throws 1000 iron cannonballs at enemy ships. The cannonballs are supplied by conveyor belts either side of him.

Past Story
Monkey D. Garp is a Marine hero, who was famous for cornering and fighting the late Pirate King, Gold Roger numerous times in his career. . Garp is considered by Whitebeard as one of the few people that know the seas from the time of Gold Roger. As part of his duty, in the past he chased other pirates like Shakuyaku.

Prior to Roger's execution, the Pirate King requested that Garp would take care of Ace, as he thought Ace did not deserve to be branded a criminal due to being born into a family of a pirate.

Early on in Luffy's life, he was trained by Garp to become a strong Marine. Luffy was thrown into valleys, left alone in dangerous forests, and tied to balloons over high altitudes, all for the sake of making him stronger. After this he left Luffy and Ace in the care of Dadan.

Koby and Helmeppo's Chronicle of Toil
Garp is first introduced in Koby's mini-series as the Marine Officer in charge of escorting Captain Morgan. However after falling asleep, Morgan makes his escape by striking Garp and taking Helmeppo as a hostage, fleeing on a small dingy. Garp then wakes up unharmed, apparently breaking a cannon in the process of waking up.

When Koby begs to chase after the two, Garp allows Koby to pursue them. Upon the boys return they offer themselves to be punished. Garp instead proposes a different course of action. He states that the pair of them are nothing but trouble and the only way to ensure they stay in line is that he takes charge of the pair. He takes them back to Marine HQ, however Koby accidentally reveals he's friends with Luffy while Garp was listening. Despite Koby trying to keep Helmeppo out of trouble he takes part of the blame stating it's "Regiment Responsibility" (which contradicts one of Koby's earlier statements that Helmeppo only uses that term when it suites him) Garp (rather then dismissing them) tests them with a fight, after the fierce (for them) battle he starts personally training them to be great Marine officers.

Reunion in Water 7
The startling revelation was made that Garp is the grandfather of Monkey D. Luffy. He also punched a sleeping Luffy and actually hurt him severely, to which Sanji comments it shouldn't as Luffy is made of rubber (which should reduce the force of the blow) - at which point Garp comments that "there's no way to dodge a fist of love". It is also revealed Dragon, an infamous revolutionary and the man branded as "the worst criminal in the world", is Luffy's father (and also Garp's son).

He left Water 7, stating he wouldn't arrest Luffy and would tell Marine HQ this was because of him being his grandson (which one of his crew replied that it would be better to just say he got away). He then left Water 7, leaving the Straw Hats to go through the rest of their stay in peace.

However, on their last day on Water 7, Garp returned under orders of Sengoku to finish off Luffy. Apparently Garp let slip Luffy was his grandson on a Den Den Mushi to Sengoku. While there, he picks up Aokiji who was in Water 7 at the time who claims he is making sure Garp obeys his orders. Luffy and his crew find themselves under attack from Garp who claims Luffy will just have to die at Water 7 (though it's obvious he doesn't believe that in any way). He throws cannonballs with his fists and finally a giant ball on a chain. The Straw Hats, using their new ship the Thousand Sunny managed to escape from Garp. Garp and Aokiji both seemed happy this had happened.

Annoying Sengoku
After his grandson's assault on Thriller Bark, he was seen at Mariejois, with Bartholomew Kuma and Fleet Admiral Sengoku, where he laughed at how Luffy had avoided capture by Kuma and annoyed Sengoku by talking about tea and crackers.

Recently, Garp found out that Silvers Rayleigh was to be sold as a slave on the Sabaody Archipelago, whom he assumed let himself get captured to pay off a gambling debt. Due to the Marines being busy with the incident regarding Whitebeard and the execution of Portgas D. Ace, Garp remarked that he would take care of the situation, although the exact actions he took, if any, remain unknown.

He was most recently seen checking up on Ace in Impel Down, to the great displeasure of Sengoku. Upon Ace's request to die, Garp merely tells him to cool his head as Ace's death won't stop Whitebeard. They are later seen discussing family issues, such as Ace and Luffy's eventual turn to the lifestyle of piracy, instead of becoming Marines as he expected, and their father.

Garp is informed while at Marine HQ that Luffy broke into Impel Down and is rather amused about it, even proud of him. Sengoku however is clearly not amused, and says that if it weren't for Garp being a hero to the marines he would have him punished for his family's behavior. Garp however, just laughs and states he doubts an old man's life could atone for his family's actions.

Current Events
Three hours before Ace's execution, Garp walks with Sengoku to the execution platform. Sengoku tells him that he will tell them everything. Garp responds to do as he (Sengoku) likes, and turns away. As Sengoku begins his public announcement before the execution platform, Tsuru tells Garp that it wasn't his fault, to which Garp just laughs and says that women get so sentimental at times like these. Sengoku then publicly reveals that Ace is truly the son of Gol D. Roger, and Garp remembers that Roger personally begged him to protect his unborn child.

Major Battles

 * Vs. Gold Roger (none seen)
 * Vs. Morgan
 * Vs. Koby and Helmeppo
 * Vs. Luffy

Early One Piece
While unnamed Garp was introduced in Romance Dawn V.2 (featured in Weekly Shonen Jump magazine itself) as Luffy's Grandfather. For a long time, it was first thought that Luffy's unnamed Grandfather was a sole addition to Romance Dawn V.2.

Some aspects of his character remain from Romance Dawn version 2. He is as hot tempered as ever and intolerable to Luffy's antics. Like the final version, he was determined to make Luffy follow in his footsteps, however here he is a pirate captain, a complete opposite of his current occupation. Both stories have in return Luffy completely rejecting the idea of following in his grandfather's footsteps. Garp now adorns a dog hat and compared to his Romance Dawn V.2 version his upper body is much more muscular compared to his chubby V.2 self. One feature carried over from Luffy's grandfather from V.2 to the final version of Garp was the scar on his left eye.

Also, Luffy got both his hat and the Devil fruit he ate from his grandfather in V.2, not Shanks. According to Oda the reason for not featuring Shanks was that he wanted Shanks to be kept a secret until One Piece was serialized so he would have a greater impact.

Trivia

 * In the anime, Garp said he has eaten 842 doughnuts without sleeping or taking a break because he was trying to beat a world record.
 * Garp's dislike of Shanks' influence on Luffy could be a reference to Oda's final decision to use Shanks (who was introduced in Romance Dawn V.1) as Luffy's inspiration in the final Romance Dawn version instead of Garp.
 * Garp is the last optional boss in One Piece Unlimited Cruise episode 2.
 * Garp's laughter style is that he adds either "Bwa" or "Wa" before the haha part. This is somewhat unique as most characters only stick with one laughter.
 * So far, Garp is the only Vice Admiral to combat against the Straw Hats
