Koga "Sea King Hunter"

Koga was a turtle that used to live around Bee Island, in the Grand Line. However, unlike other turtles, Koga liked battling wild animals and used to challenge many small sea kings to battles. During the years he lived in the sea around Bee Island not only he created its unique battling style but also it managed to get granted enormous strength. One day, though, Koga was attacked by a bunch of some strong Sea Kings who had grown tired of seeing him defeating weaker Sea Kings. The turtle was utterly defeated and was abandoned at the beach of Bee Island, almost killed. However, he was very lucky and he was found by a young woman who took care of him and helped him heal from his injuries. She took him in her house and used to play with him and feed him. At the meantime, when Koga was staying at the woman's house, he found and ate IQ and due to his interraction with humans he was granted the ability to speak and his battling abilities increased a lot. After that, he was able to swim much faster, jump high in the air and stand for a short period of time like a human.
One day, as he was swiming with the woman, he was attacked by the same Sea Kings who had attacked him some time ago. The turtle got injured once again and in an attempt to save him the sea kings injured the woman. After that, the turtle got angry. The woman had nothing to do with them and they should not harm her. The turtle barely managed to beat one of the many Sea Kings but he saw that the woman was bleeding the whole time and so he dragged him out of the sea and tried to carry her to the town. In the middle of the road, though, the woman passed away... Since that moment, the turtle was determined to get much stronger so that one day he could protect himself and his friends from getting injured by sea kings and swore that he would destroy every sea king he happened to find in the middle of his road.
And now, three years later, after training himself to the very limit, the turtle is about to set off on a journey in an attempt to eliminate all the Sea Kings he can find...

One day, while on his journey, the turtle happened to come across a mermaid and another man with the ability to change his face. The man and the mermaid belonged to a pirate crew. They were both members of the Avenger Pirates, a group that was ruled by the pirate captain Maximillion Maimou. In the crew, there were many other strong members such as Shrieker Gatroid the great white, Toshiro who was a cyborg that could turn to a demon thanks to a Devil Fruit, Nick Rush who was a scientist with the abilities of the Goro Goro no Mi and many others. Koga decided to stick with the crew and during this time he happened to meet with one of the seven warlords of the sea, the Shichibukai named Gael Iura.

After the meeting on the warlord's islands, the crew reached Shabondy Archipelago. There, while Maximillion was approached by the Warlord, at that time, whose name was Roberto D. Wally, Koga searched the place and he learned more things about it, including the Shabondy War in which many pirates starred and shined. In these pirates there were the yonkou Anubis, Roberto D. Wally and many others with high bounties such as Maxulus N. Crow, Ryan and of course Satoshi Miroku. These three people would later be known as the commanders of the Anubis Pirates, serving right under Anubis himself...

After Maximillion agreed with Wally to form an alliance, he decided to keep his end of the bargain as he had a lot of things to earn from the Atlantis War. However, at that time, while he was conspiring with the Warlord, he informed the members of his crew that the main goal was to steal Oro Jackson and use it as their own ship. Many of his crewmembers tried to steal the ship, including the master thief known as T.H., while Koga was watching at the sides by destroying the cannons of the underwater dome in order to protect the pirates from getting blasted off by the cannon balls of the place.

While Koga was destroying the cannons of Atlantis, the place started sinking because of the Buster Call that Jiper Juicest, one of the marine admirals called. At the time the place was sinking, Koga found himself trapped in the underwater dome. He had been lost from the rest of his comrades while Maximillion seemed to be missing. Koga thought that he was doomed and that he would die... Even if he could survive in the water, he still could not escape the battleships that were attacking the place. He was prepared to die...

God had other plans for him, though. As he accepted his fate and got ready to get eliminated by the marines, he noticed that the admiral who called the Buster Call was defending the place for some reason. He could not understand why he would do that, but that could give him some more time to escape from the place. With a smile on his face, the turtle started following the marines to see where they used to get out from. After some time, he finally managed to get out of the underwater dome. However, as he had no ship to get out, the tiny body of the turtle could not handle the pressure of the water and he started moving up without noticing. As he moved upwards, he could feel his body hurting more and more, the speed he was thrown out constantly increased and in the end he ended up getting thrown away by the sea with much force, landing on a small island.

For several days, Koga lived there. Seeing his weakness that made him get lost from his crew and got him almost killed, the turtle started training more and more in order to return back at the Avenger Pirates as a powerful comrade. During that time, he tried to use a technique that would turn him into a human. Even if he could not completely, he felt that if he tried he would probably do it because of the consumption of IQ he once had. And so, he kept training and training, hoping to achieve the results...

While he was training on the island, one day, a dingy approached him. The dingy belonged to none other than Maximillion, who was once again sailing the seas in order to reassemble his crew and become the captain that they did not have. He wanted to become a better person. It seemed that something had changed him... Koga did not know if Maximillion would act like this forever or not, but he started liking him again and started trusting him. The turtle agreed to follow him once again as the pet of his crew and so the two of them set sail around the seas to achieve their goals.

Afterwards, Koga learned why Maximillion got lost in the Atlantis War. He was beaten down by the Vice Admiral named Zigfreed Von Strudel, a powerful marine that claimed to not have lost a battle in his whole life. Maximillion told Koga that even if he decided to try and become a better person, he would have to settle his old scores and so the crew started chasing him in order to take him down. While searching for him, the crew came across Frank, an undead zombie with the powers of the Yomi Yomi no Mi that entered the crew as the musician.

The three of them started searching together and one day Maximillion somehow found where Zigfreed was assigned. He was assigned to G-8, a place also known as Navarone. However, while they were on their way, the crew found a cruise ship. On that ship, the man they were chasing was standing. Zigfreed Von Strudel was there... and he was ready to battle them. During the battle on the ship, the crew got easily eliminated and Koga fell asleep thanks to the Vice Admiral's Nemu Nemu no Mi abilities. And not only that but also those who tried to assist the crew also lost in the battle...

Those who lost to Zigfreed, though, were invited to a game. The Vice-Admiral wanted to play a game with them for some reason. With that game, he would give them a second chance... At least that was what he claimed. As the game started, the crew realised that they had to fight Zigfreed's special squad and defeat them before taking on the powerful marine. Koga and R.A.M. 2, a new member of the crew, battled Jelayir, one of those marines and managed to beat him down with their combined efforts. During the time in the fortress, Koga also started thinking that Maximillion sold them to Zigfreed. However, he proved to be wrong and when he aknowledged that he felt that his bond with his captain was slightly stronger.

After the events of Navarone, Maximillion's bounty errupted from 50,000,000 Beli to 150,000,000 Beli. That made him a very wanted pirate... Now, the crew would have to be more careful and watch their movements. Maximillion, though, had other plans in his mind. After listening to an announcement of the marines that said that his brother, Manta Maimou had been caught, the crew headed for Water 7. There, Maximillion and Manta found theirselves engaged in the Unholy War. Koga was trying to search for them with R.A.M. 2, but he seemed to be unable to find them...

When the war ended, Koga was shocked to hear that his captain had been caught by Major Payne. He thought that this was all a lie. However, Manta ensured that Maximillion had a plan and that he wanted them to go and save him. Manta was then decleared as the captain of the Dusk Pirates because he knew Maximillion better than anybody else and the crew started training in order to help Maximillion get freed. At that time, Koga used his turtle fishman technique and his body turned into a body that ressembled a human's, making himself something like a fishman. Also, while training the crew met Suigo of Wally's crew and they had a meeting with them. Alexander D. Remmington also joined...

When the time came, the crew attacked Impel Down two days later. They progressed from floor to floor in order to find their captain and save him. They moved through level 1 and 2 and in level 3 a big battle started taking place between the Impel Down Guards and the pirates. During that battle, Koga freed Shrieker Gatroid from his cell, the former first mate of the Avenger Pirates who somehow ended up getting jailed in Impel Down. In level 5, Koga went through some major changes. Quincy, the doctor of the crew injected him with SIQ and Koga's body went through some major changes. He got bigger in size and not only that but also when Koga attempted to use his Turtle Fishman technique, he noticed that the change was permanent and that his body was changed because of the great amounts of IQ and SIQ he happened to consume. His size at his turtle fishman form as 1.85 meters tall and he had a big scar at his chest... It seemed like the last times he used the technique were just a state before he completely transformed...

Also Koga was the one to reach Maximillion in order to free him and would do so, if he wasn't stopped by the Vice Warden. However, the unexpected help the crew received from Lecter Kageroza, a Chief Guard, allowed him to have Maximillion freed. Afterwards, the crew started getting out... At level 2, when Maximillion reunited with the crew after his battle with the Warden, Koga noticed something. Maximillion was turning back at his former self...

When Maximillion faced Lecter in a battle and defeated him, he gave Koga Lecter's weapon. Jigen Naginata, a naginata that had consumed the Jigen Jigen no Mi and could create portals for a seperate space world. Koga did not know how to use it at first, but then he started training it in order to master it... Also, Koga started training his techniques more and more, being able to use his Shellwave technique more regularly than before and without getting tired from it.

And then, in the end, when the crew reunited, they all got out of the prison. They started sailing the seas once again... And while they did so, Koga's bounty was raised to 20,000,000 Beli for his actions in Impel Down.

While the crew was sailing in the Calm Belt, something unexpected happened. The crew happened to meet a bunch of marines who were actually searching for them, preparing an attack against them. The captain of the Hooded Knights, Darnel, a man that Maximillion fought in the Unholy War in Water 7, was searching for him to attack him. Along with him, many other marines were coming, including the Vice Admiral Derge Sr. and Lenny, a marine captain with the deadly Devil Fruit ability of the sun itself. Those, along with the rest of their crews were coming and a battle was about to start.

As the battle started, Koga found himself engaged in a battle against Benjamin, a man that belonged in Lenny's crew. As the two of them battled, Koga would use his naginata to stop all of his ranged attacks and try to strike him afterwards. However, that battle would not last for very long as something was about to take place that would affect him completely.

When Derge Sr. attemtped to attack Maximillion, R.A.M. 2, his best friend and the navigator of the Dusk Pirates, got in front of the attack and he was completely destroyed by the Vice Admiral. This enraged Koga, who took R.A.M. 2's Subagun and tagged himself with his captain in an attempt to defeat Derge Sr. and Lenny. In the battle, Koga would use his naginata to redirect the attacks of his enemies against them. Knowing that he had no strength that could much theirs, he decided to try and use their own strength against them. However, Derge Sr. quickly thought of a way to beat that strategy and Koga found himself once more at a disadvantage.

And as the battle went on, Maximillion made his proposition. He asked the marines to allow his crewmates to leave while he would take them all, alone. That speech of Maximillion enraged Koga, who realised that Maximillion kicked him out of the battle and would not allow him to avenge R.A.M. 2. As a result, he left from the battlefield and he quit from the Dusk Pirates. However, when Maximillion was about to drawn, it was Koga who reappeared to save him from drowning and he moved him to a nearby island where he would rest and cure himself. That was a way of paying Maximillion back for the time they spent together and it was the last time they met with each other. As Maximillion was badly injured and his clothes were completely destroyed, Koga gave him his own clothes except from his pants before he left him on the bitch of the island on which they were on... Afterwards, Koga dived in the sea and he finally left, only with his naginata and R.A.M. 2's gun.

However, even if he quit from the Dusk Pirates, he still got a bounty increase. For his smart maneuvers in the battle against the Marine Captain and even the Vice Admiral himself, and because of the fact that he escaped from the marines easily, thanks to his weapon, he was given a bounty increase of 15,000,000 million, making his bounty 35,000,000 Beli.

After this, Koga realised that Maximillion had just returned back to his bad personality and that he only cared about his own power, once again. As a result, he decided to never give him another chance and so he quit the crew without even saying anything to him and the rest of them. And while he travelled by himself, something unexpected happened. The pill that Quincy gave to him in Impel Down started affecting him. He started growing slightly older. He could not see well without glasses so he put on glasses on his eyes and he grew shoulder-length black hair on his head. Also, he stole clothing from a marine. Now, he wears a marine coat on his back, white pants, white shoes and white gloves. Even if he does not look very much aged, he looks older than he looked before the effects of the steroid affected him. Finally, his body developped more but not to the point that it starts declining, making himself stronger, and not weaker. All of Koga's abilities now are greater than before, except from his vision. Also, he started training himself at the usage of the naginata, making himself a less than expert user of the weapon.

During his travels while he was going by himself, Koga ended up finding one of the sea emperors, Iken as well as a few others (Emily, Tsujo, Chi). However, during their meeting, something unexpected happened that was about to cause ultimate chaos to the islands around and even the whole world. The mythical Hito Hito no Mi: Model Pele was used on a volcano and the mythical Pele creature was created. When that happened, Iken started fighting the creature with everything he had, but in the end he ended up losing to the monster. Koga, who was watching the battle from afar realized that he could not do anything against the monster. However, he also knew that if there was a person that could save Iken, and a girl named Emily who was around, that person was him. As the two were in the sea, nobody else could dive faster than Koga, who was actually a turtle humanoid and he could swim fast. In the end, after searching for them for quite a while, Koga managed to find them and saved them and in the end he brought them to a place that was nearby; it was none other than Atlantis, the place on which Iken made himself known to the world, the place where Koga saw him for the very first time. But, except from that, something else happened, as well... As Koga was seen with Iken and was also seen diving to save him, he was reported to the marines as "The double agent pirate", a pirate who was affiliated as a friend of two different Yonko. That resulted in a small bounty increase, from 35,000,000 beri to 40,000,000 beri.

For quite a while, Koga travelled along with Iken in order to help him take down his former lunatic captain, Maximillion Maimou. When the two of them met a grand battle between the two Yonko started and Koga was in the middle as he wanted to save them both. He wanted to save Iken from death and he wanted to save Maximillion from his madness. Most of the time, Koga stood on the background, looking at the two men who were willing to do anything to eliminate each other. He knew that if he interfered, he would mostly end up dying as collateral damage. However, in the end, when Maximillion took a powerful blow and the two of them were on the verge of death, Koga appeared behind his former captain and he used his Devil Fruit weapon to open up a portal that would trap Maximillion in the parallel world of the weapon, forever. Koga used the very same weapon Maximillion gifted him when they destroyed Impel Down against him and finally brought an end to the activities of the evil Yonko.

Since then, his life changed significantly. He became the target of the World Government as they wanted to find out where he hid his weapon and thus, Maximillion. In order to expose him, they put a bounty of 410,000,000 Beri on his head, increasing it vastly and for no reason as he could unleash one of the most dangerous humans to exist on the Grand Line at any moment. And considering for the World Government the danger that Derge Namikaze and Roberto D. Wally already possessed, they wanted to control the weapon Maximillion was trapped into. Ever since then, Koga went into hiding. From that point and onwards, he started training more on the mastery of his turtle combat, the former fighting style he used in order to become stronger and protect himself from any enemies who were after his head. And now, he is travelling all across the Grand Line trying to hide from any Bounty Hunters, Marines and Pirates who want the price on his head.

In this form, Koga's strength, speed and durability are greatly increased. Because of the great amounts of SIQ and IQ Koga happened to consume, his body was modified and altered, making the effects of the technique permanent.
-Shellwave: Koga can only use this technique while in his Turtle Fishman form. After receiving an SIQ injection from his crew's doctor, Quincy, his body doubled in size in his normal form and much more in his Turtle Fishman form, giving it more strength. As a result, he was able to perform this technique and launch a blast of compressed air with the assistance of his shell by moving his natural weapon forward swiftly. The technique was tiring for Koga as he could not adapt easily to his double sized body. However, after training over it, he managed to start mastering it to the point that he could perform several Shellwaves without getting tired.

-Memories of the Past: Memories of the past is the technique that Koga uses with R.A.M. 2's Subagun. The humanoid turtle shoots himself with the Subagun's beam, increasing his speed greatly for two posts. All of Koga's movements have twice the speed while he is under the effect of the beam.
-Turtle Warrior: Koga's new supporting technique. Koga grabs his naginata on his right hand and his shell on his left hand. His naginata is his weapon and his shell is his shield. As a result, he calls this as a warrior mode. This technique has a psychological effect, making him believe that he is stronger in this form and so he gives out the best of his abilities. (NOT ANYMORE)

-Turtle Fishman: Koga had been training on performing this technique for very long and he finally perfected it so that it would work as he wished after the battles in Navarone. The turtle focuses its strength and its muscles get bigger and bigger to the point that his form changes from that off a turtle to that of a turtle fishman. In this form, Koga's strength, speed and durability are greatly increased. Because of the great amounts of SIQ and IQ Koga happened to consume, his body was modified and altered, making the effects of the technique permanent.
-Shellwave: Koga can only use this technique while in his Turtle Fishman form. After receiving an SIQ injection from his crew's doctor, Quincy, his body doubled in size in his normal form and much more in his Turtle Fishman form, giving it more strength.

The technique was tiring for Koga as he could not adapt easily to his double sized body. However, after training over it, he managed to start mastering it to the point that he could perform several Shellwaves without getting tired. After the events of the Calm Belt battle, Koga further trained the technique and now he has finally become able to launch many of this attacks without getting damaged.
-Shellwave Barrage: Shellwave Barrage is a variation of Koga's Shellwave. The humanoid turtle swiftly moves his shell forward, launching many compressed air blasts towards his enemies. It is a quite powerful attack but using this attack twice can start tiring Koga. After he went into hiding, he finally mastered it to the point that he can perform it up to 5 times consecutively. (For an idea of how it looks, it is similar to Rokuougan)
-Flying Turtle: A new technique of Koga. He throws his shell with great force towards a direction and he jumps on it quickly, traveling on top of his shell as if he is flying with it. It is a technique which can be used to escape a battle and he developped it to avoid those who pursued him for his high bounty. (Similar to General Tao's means of transportation back at the original Dragonball).
-Shell Magic: A new technique of Koga. He developped it after meditating for months and while on hiding. He is using a minor variation of Life Return he learned by himself controling his shell from a distance. This allows him to move it in a form of telekinesis as it is his own body part. He is using this stance to perform several attacks from a distance, striking his enemies from behind.
-Memories of the Past: Memories of the past is the technique that Koga uses with R.A.M. 2's Subagun. The humanoid turtle shoots himself with the Subagun's beam, increasing his speed greatly for two posts. All of Koga's movements have twice the speed while he is under the effect of the beam.
