Shanks the Red
In the Beginning
The first known stage of his life is when he worked on the Oro Jackson as a cabin boy with Buggy the Clown
. They were both under the supervison of Silvers Rayleigh , while on Gol D. Roger's Crew. At one point the crew encounters a devil fruit (later revealed to be the bara bara no mi or "chop chop fruit) . A devils fruit is a cursed fruit which is said to give enormous powers when eaten, but the person who consumes it looses his abillity to swim at the same time. Buggy knew its value and wanted to steal it (since it could be sold for 100 million beli ) , but when he tried, Shanks came and Buggy hid it in his mouth. Shanks scared him by mistake and Buggy swallowed the fruit. Since then he blames Shanks for loosing his abillity to swim.
Years later Shanks was a well-known and dreaded pirate, but a peace main (pirate, who just steals from other pirates and fights only to protetct his own life or the life of one of his crew members and friends). He was a legendary swords-fighter, who fought Hawk Eye several times.He often visited the island, on which Luffy lived. When he visited it for the last time, he brought a devil fruit, which was accidentally eaten by Luffy, who then gained his known rubber powers. Later another pirate crew mocked Shanks, while he didn't fight back. Luffy, disappointed about his idol, tried to fight the crew alone. Shanks came to save him but failed. The captain kidnapped Luffy and wanted to throw him into the sea, where Luffy would drown. Shanks came to save him again but was attacked by a monster of the sea, which ate his left arm. Thereafter Shanks chased it away by just scaring it with a glare ( later revealed to be Haoshaku Haki or "Color of Armaments" haki) . Luffysad about Shanks' arm, then swore to become the new pirate king. Shanks gave him his beloved straw hat and told him to give it back, when he reached that aim. After that Shanks' crew departed.
Ten Years Later
Ten years later Hawk Eye and Shanks meet again, because Hawk Eye has met Luffy and recognized his hat. He tells Shank about Luffy's bounty, which has an amount of 30.000.000 belly. Later it is shown that Shanks is know one of the four Yonkou (emperors of the sea) , who rule over the second half of grand line (called the New World) . He tries to contact Whitebeard, the most promising hunter for the One Piece (former pirate king Gold Roger's treasure). This alarms the world government , because if the two team-up (the two most powerful pirates in the world) this would cause another disruption of the balance of powers. The other disruption is caused by Luffy, who stops one of the Seven Schichibukai (seven warlords of the sea) after the other. When Shanks and Whitebeard finally meet, Shanks advises to stop Ace
from hunting Blackbeard, because Blackbeard would kill Trace, if they met (Crocodile and Gecko Moria). Whitebeard declines his offer and the two clash weapons , causing the "heavens to split" .
His latest appearance is when he arrives at Marineford to end the war , and give Ace and Whitebeard a proper burial .
