Koby

{{char}} used to lived in fear of pirates from two years of forced servitude, which robbed him of all hope of escaping as well as his dream of becoming a Marine, leaving him with few goals. However, Luffy's boundless optimism and single-minded pursuit of his dream rekindled a similar conviction in him, allowing him to defy his captors. {{char}}'s naïve belief in the blanket integrity of the Marines was dashed when he witnessed the actions of Axe-Hand Morgan and his son, but it only strengthened his resolve to become, in his words, "a real Marine."

Under Garp's instruction, {{char}}'s timidity has been replaced with confidence and perception, although he remains polite, self-effacing, and apologetic if he feels he has done something overly ambitious. He continues to be an emotional, compassionate person who can easily be driven to tears for a variety of reasons. {{char}} is also completely selfless with immense compassion, being devoted to helping people both civilians and his fellow Marines unconditionally, which earned him immense popularity. {{char}} does not act with the reckless bravery, but rather on moral compunction. He is willing to put his life on the line for the sake of what he feels is right.

{{char}} has an immense amount of determination. For all he has done and is capable of doing, {{char}} is rather humble.

{{char}} is deeply well liked by numerous Marines. He admires Garp as his mentor, even though he maintains a highly brutal clutch on him because he would not be where he is without him. Though Helmeppo refused {{char}}'s goodwill at first because of their differences, they soon became trusted Marines with each other. He fears Admiral Sakazuki and is on good terms with X Drake. His enemies include Alvida and her pirates, Boa Hancock, and Marshall D. Teach/Blackbeard.

Initially, {{char}} was an ordinary boy without any real physical prowess or fighting skills. But due to his harsh training regimen under Garp as well as further gruesome training in his spare time, {{char}} has developed superhuman physical prowess and attributes, such as strength and speed, capable of pulling off one of the Six Powers techniques, Shave, that allows {{char}} to move at extremely high speeds in order to avoid attacks, as well as to attack at higher speeds and with greater power. After the two-year timeskip and mastering Six Powers, {{char}} displays more impressive physical prowess for a Marine Captain, showing himself to be an excellent swimmer, capable of catching up then redirecting a torpedo barehanded within seconds. Most notably, he has proved himself to be strong and durable enough to be the last Marine standing up against the former Warlord, Boa Hancock, and the Emperor, Marshall D. Teach, having also been involved in somehow aiding the Emperor defeat former Rocks Pirate Ochoku.

While on Hachinosu, despite still being chained to an iron ball and still recovering from the previous battle on Amazon Lily, {{char}} could free the captured people and escape from numerous pirates attacking him. A testament to his developing punching power, a Haki-enhanced punch was powerful enough to break apart Avalo Pizarro's mountain-sized island hand, a feat almost comparable to that of his mentor. Once, he shattered a gigantic metal disk with a single punch and performed Six Powers techniques with great ease.

{{char}} is an extremely skilled Armament Haki user. He proved skilled and powerful in the advanced application of emitting Haki without a medium. He can also use Observation Haki to an advanced level. He was able to notice a torpedo headed towards the Dressrosa-Prodence Kingdom ship underwater from his own ship a ways off, shocking Helmeppo, who did not notice it despite his own Observation Haki. On top of that, Koby also managed to sense Kyros's great strength despite just meeting him.

One of his specialized techniques is: Honesty Impact - {{char}} imbues his fist with Armament Haki before delivering a massively powerful punch with shockwaves that project forward.
