In the anime, his eye color is blue, and his hair is gray, whereas in the manga, it is white.
Over his many years as a Marine hero, Garp has made many enemies with pirates over the sea, such as It is unknown how they met, but they have known each other for at least 22 years, since Garp was seen entrusting a newborn Even though Dadan usually fears him, she did not have a problem attacking Garp for not managing to save Ace. There was a conflict at God Valley that required Garp to team up with Roger in order to put an end to his reign of terror. When Momousagi mentioned Luffy being targeted by two Emperors, Garp did not express much concern about it.
After this, he left Luffy in the care of Dadan.
In terms of Haki, I am unsure as to if Garp has the Conquerors Haki. Garp about to punish (or in this case, train) Luffy and Ace.In the anime, a young Luffy blurted out that the trio shared a promise over a shared drink. He initially refused to capture Luffy in Water 7 until explicitly ordered to do so. He also wields a giant iron ball, mounted on a chain, which dwarfs the size of his own Marine battleship. IIRC Marco wasn't even paying attention to Garp. He was able to get back on his feet after allowing himself to be punched by Luffy in Gear Second at point-blank range without losing consciousness, and was still able to fight the Blackbeard Pirates along with Sengoku. During the Battle of Edd War, Garp's had two black stripes on his epaulette… He wore a dark suit with an orange striped undershirt and a black tie. Unlike many Marines, Garp does not believe that a person's lineage determines their path. Garp responded by saying that Luffy was negatively influenced by Shanks, to which Luffy took offense because Shanks saved his life.
Even in old age, Garp retained his strength. He was also the one who trained Luffy and Ace into being strong enough to set sail on their own. With the end of the war, Garp took up a station in It was later revealed that both him and Sengoku stepped down from the Marines. Before Roger’s era, Rocks was his enemy.
They later discussed family issues such as Ace and Luffy's turning to the life of piracy instead of becoming Marines. Like Luffy, Garp is extremely blunt and honest when talking to people, as seen when he openly badmouthed When Garp prepares to fight seriously, he often removes his Marine coatAs the "Hero of the Marines", Garp is overall very well-respected for cornering the Garp has problems with respecting his superiors and such is the case with then-Fleet Admiral Garp's crew often reacts with shock or uncertainty to his behavior. This was not shown in the manga. Early on in Luffy's life, Garp trained him to become a strong Marine. Garp broke through the wall and into the Straw Hats' room. Garp is a tall, tanned, broad-chested, muscular old man. They are only two marines in the Navy that don’t have rank of an Admiral,but are admiral level characters. He was huffing and puffing, he most likely didn't have the strength to keep fighting for long.
Garp uses Busoshoku Haki to flatten Chinjao's head.As a vice admiral, Garp is fully capable of using Haki.He could harden his fist and turned it obsidian black, allowing him to counter and even crush Garp throws cannonballs with his bare hands. After Luffy was hurled over the siege wall and stood before the three admirals, Garp was shown to be worried about his grandson.
Garp is easily one of the most powerful Marines and one of the strongest characters seen in the series. The hero of the Marines or just an old geezer? Thus, he allowed Luffy to land a Gear Second punch that sent him flying and smashing into the ground, much to the shock of the Marines watching him.
