Ax Colt is born on an Island in the South Blue, Big Tree Island, named after the massive trees that grow there. His father, Hammer, was a shopkeeper in his daytime, but also worked part-time as a captain in the Big Tree Island Militia, as the country was loyal to their royals, and not the World Government, thus, they did not recieve Marine help to fend off Pirates, or other bandits, as Pirates were rather rare during Ax's youth. His early years were unremarkable, he was a regular kid, he laughed, he played, he never had a mother – she died during childbirth, never really weighed on him. He joined the militia at 12, four years too young to normally join, but he lied to the other officers about his age, and they believed him, letting him join them during their training.
He fought bandits, stopped thiefs, protected officials, that sorta thing for an entire year, making an okay wage doing it, till his father found out and forbid him from continuing – he didn't listen, this only caused a great rift between father and son. Ax had an apptitude for battle, to prove himself – to do great things. He learned how to fight with a Gladius and Buckler, like all of the soldiers of his home. At fourteen, the island was invaded by Pirates – Slavers, in fact. The army fought them off bravely, but not without a cost. Dousins of their frontline soldiers had been taken captive – Ax being one of them.
Hammer was beside himself, and manned a rescue. Meanwhile, The captors were under the banner of "Four Finger Feenix." A mad pirate whom legends said had gnawed his own fingers off, and would cut off the fingers of anyone who crossed his path. Feenix cut off both of Ax's ring fingers, as he did with all of his prisoners he had captured, as a sign of dominance. After weeks in captivity Ax staged an escape on the pirate ship, breaking out of captivity with a handful of his fellow Big Tree natives, plus some of the other captives, he lead them out of the pirate ship once it had docked, during the cover of night. Their weapons and armor had been stolen, so they had to improvise. Sharp rocks and hard sticks became their weapons – except for Ax, whom found a woodcutters axe stuck into a tree. The weight of the metal head served his natural strength and agility rather well, forgoing the use of a shield for the increased power behind every swing. Ax got his revenge against Feenix, decapitating him with that very same weapon, putting a eight million bounty to rest.
They never did find out how to get back home, instead, Ax made his way onto a Marine vessel, and enlisted. Once more, he lied about his age, claiming to be a whole 16, not 13, and he was allowed onboard the S21 unit, the only one in South Blue at the time. He spent three more years in the South Blue, never once returning home to Big Tree Island, his father still searching for him, Hammer's grief never struck Ax's mind.
At the mere age of 16, Ax was snet off to Marineford to undergo officer training, them believing the make-believe 19 year old to be worthy of a officer rank, and so it was he became an Ensign, and began his work in the Grandline.
Young Ax Colt Ax has over the years taken more bullets to his flesh, more swords have grazed his skin, and more flames have singed his body than just about anyone in the Marines, yet, he survived it all, refusing to die as if by stubbornness alone. At age 18, he became a Captain, his military career was a success, an excellent combatant and commander, bringing his crew together and overcoming one great threat after another.
Ax suffered his first defeat as a Commodore, in the Grandline. Aged 24, fighting on a small set of Islands in the middle of Paradise. His platoon, G11, Patrol 6, were outnumbered against six crews of pirates, in a free-for-all battle royal. Ax and his Ensign, and Protegé, Liam Northgate, faced off against 3 of the captains and first mates of those ships. Ax lost his eye, but Liam paid the ultimate price. His first great failure, and one that would set it's marks forever in the spirit of the young star, one with the potential to become one of the greatest Marines of his era.
He continued having a fairly succesful military career, becoming Rear Admiral by 32, and after the quelling of the Wano Rebellion, one that he had a great hand in, he was promoted to Vice Admiral by 37.
A well decorated war hero, leader, inspiration and just about poster boy for the Marines, Ax had just about it all going for him. But he still wasn't happy. He had forgone his roots, given in to his pasion for justice, and kind of lost himself in it. Doubt began to grow inside of him.
Vice Admiral Ax Colt As a Vice Admiral, he did surprisingly little. He partook in a few battles, traded blows with some of the greatest Pirates to ever live, even going so far as to being part of a unit that fought against Gol D. Roger's pirates himself. He was there for Roger's execution, part of the security detail, guarding the town where Roger met his end, fending off the many pirates that did try to save him, but it was all in vain.
Colt saw Roger's final look. How he died grinning, and it unsettled him, rattled him, even. How could someone so evil, so rotten to the core, be pleased with himself when everything he had worked for was in ruins?
He began faltering in his duties, drinking a little too much, spending a little too much time writing his less-than-excellent poetry. But it all came to a heed five years ago, when he heard a ringing he had never heard before. His silver Den Den Mushi rang, as it did on the 2 other warships that were nearby. The greatest military action on all of the seas had been issued. The Buster Call.
And to make matters worse, it was on his home island, Big Tree Island. The royal army had become too strong, and the World Government decided that would be enough, to not further escalate the situation they would put the entire island down, grind it into dust and leaving nothing but ruins.
Ax would have no part in it, he tried contacting HQ to call the attack off, but they would not listen to him, he had not authority to make the call, it came from the Den Den Mushi of an Admiral. And so, his ship sailed back to his home, where he had not been in four decades, to destroy it and eliminate any ties to his past he ever could have had.
His men understood this was very hard for him, and put their loyalty to him over their loyalty to the Navy, or to the World Government. When the buster call was initiated, Ax's ship did not fire a single cannon on the island, instead they spent the entire time actively protecting civilian ships, putting themselves in harms way, shooting out volleys of their fellow Marine's fire.
Ax met one of the other Vice Admirals, Markos, a scyther wielding lunatic whom had been undercover as a pirate captain for the past few years, a hotshot whom made Vice Admiral even younger than Ax did, truly impressive. Markos boarded Ax's ship and demanded an explaination for this treason, and Ax explained he would not let the Marines just kill his home.
Markos attacked Ax on the spot, and the two Vice Admirals duked it out for more than a day, both sustaining heavy injuries, being evenly matched. But, in the end, Ax was victorious. He spared Markos life, and decided to sail away from what remained of Big Tree Island – most of the civilians had made it out thanks to him.
As he made his way back into the grandline, he was met by a marine brigade, 20 warships strong. Whom called for his arrest for treason, while some wanted him executed for his insubbordination, they instead stripped him off his rank, and sentenced him to life in prison.
Life in Impel Down, on the harshest level, Level 6. Along with all of the most hardened criminals in the entire Grandline. Life In Impel Down for a Vice Admiral was not expected to be very long – and every pirate in the entire joint wanted to take him down, be the one to kill Ax "The Headsman" Colt. Ax spent the next three years fighting every single day, sustaining injury after injury, constantly being overwhelmed, enemies at all sides. The guards did not want to help him, and the pirates hated his guts, he was well and truly alone.
Two years ago, he was released, after it had been discovered that the Buster call was created by a rogue Golden Den Den. It was a fake, the people of Big Tree Island did not deserve to die, and Ax had been somewhat justified in his actions. But, due to his punishment and actions, Ax could not get his rank restored, instead, he would be sent off into the New World, to G5's HQ, be given the rank of Inspector, and oversee their actions.
However, soon, he got dulled by the desk-work, and instead put in to be replaced as a field officer, Commodore of the Second Patrol, serving under Vice Admiral Freyja.
