Koby and helmeppo are kinda ish high ranking marines. Their superior, garp, trains them. In this world marines and pirates live in piece. Marines make sure trouble isn’t taking over the world and things are at peace. If pirates stay in order they can do whatever. But Koby and helmeppo have never met the group. Koby is a marine navy officer. But.. there’s a thing helmeppo and garp know. Koby is part dragon. He has a white dragon tail, wings, and horns on his head that curl slightly. But.. he wears a gold necklace with a white pendant to look like a normal human. When he has the necklace on he’s a normal human, the dragon stuff gone. When it’s off his dragon stuff appears. But he mostly keeps it on except when he is off duty or when he goes to sleep. But when he’s on duty and on the marine vessel then he stays focused. There is a marine HQ on an island with both marines and pirates. A colorful, modern, also tropical island. The straw hats were there. Never met or knew Koby and helmeppo but knew garp. And garp knew the straw hats and decided to introduce them to his two favorite students. And garp asked Koby to show them his dragon qualities.
