I've actually thought about this one. Wait for it…
Name: Baby Gurampsu
Age:41
Height: 4'11''
Appearance: A little barrel-shaped man with a broad, ungracious face, and greasy, wiry curls receding from a sloping brow. He wears an old leather seaman's coat and oversized tennis shoes.
Occupation: Travelling merchant
Personality: Somewhat crabby generally, not to mention something of a heavy drinker, but always willing to help a friend in need.
His business dealings are largely honest, but he will gladly cheat anyone who rubs him up the wrong way. He spends weeks at a time alone on his boat, which has turned him rather strange in some people's eyes.
His constant companions are the flocks of seagulls who perch on his boat, attracted by his cargo, whose incessant cries he has comes to understand as a simple but beautiful language. The seagulls are his true 'nakama', and one day he plans to brave the Grand Line and finally reach the Island of Gulls, where, the birds assure him, he can be introduced to the King Seagull and made a Seagull knight. Any protests by those who tell him that they're just stupid birds and that he spends far too much time alone with his imagination are swiftly ignored.
Abilities: Nothing especially special, but he owns a flying rowboat powered by breath dials that has been in his family for generations. It hovers at a constant height of about twelve feet above land or sea, and has to be boarded with a rope ladder, since he isn't sure how to land it, or indeed how to make it take off again if he ever managed to. When rowed by his strong little arms, he can keep pace with much larger vessels-- this, and its relative immunity to storms, pirates and sea monsters, make it suitable for use in the open ocean.
History: Born into a large family of poor traders on Dunnish Island in the South Blue, whose only treasure was their uncanny flying rowboat. His life has been dull and uneventful, rowing across the seas and back again selling grain and preserved fish. It's a lonely life, with few chances at glamour or romance, but it's all he's ever known. He sends most of his meagre profits back to his elderly parents and his extended family, who he sees but rarely.
However, since his epiphany from the seagulls, his life is driven by purpose. He no longer feels his loneliness, and he's keeping a little money from each sale-- no longer drinking and dicing it away at every port he passes through-- to supply his great voyage to the Grand Line!
Dream: To meet the Seagull King, whose existence remains debatable.
Fighting style: Consists of grabbing an oar and hoping for the best. As his oars are dial-powered, they deliver a hefty whack, but Gurampsu himself is no swordsmaster and tends to escape in his boat at the first sign of real trouble.
I love this guy. One day I'll write an awesome fanfic starring him.
