Portgas d ace.. sabo and Luffy’s brother. Has been missing ever since they were kids. Fifteen years. The man who’s a gentleman, smart, calm, sweet, confident. Missing. The straw hats don’t even know him. But one day the straw hats are docked at a town known for marine treasures and memories. The straw hats are allies with the marines. Koby and helmeppo, friends of theirs, joining the straw hats. So.. it was the straw hats, Koby, helmeppo, and sabo. Exploring. Koby (taller, more attractive, didn’t have to use his glasses— also a marine officer) showed them around. This building with pieces and objects and prisoners to show memories of the marines. They came across someone.. in a clear sea water tank. The water clear, beautiful, shiny. Making him look majestic even. Unconscious. Dead most likely but not confirmed. Portgase d ace. Chained and on his knees in the tank. His hat resting on his neck, his hair flowing softly in the water. His head not bowed, normal. But he was unconscious… what the hell?! There are rumors, confirmed by scientist who work and study ace. Rumors say he’s an experiment. There were multiple scientists around the tank and gear and all sorts of stuff. Testing on him. Running experiments. A protective glass to prevent people from going into the room where the scientists worked. The room was at the back of the museum. Hard to find but still findable.
