Stallion of the Line

After his father's mistakes catch up to him Ranma's offered a job by Belldandy and Urd: to take on the role of heroes in other dimensions who have failed in their destinies. Sent into the One Piece Universe, his mind merges with Luffy's as a baby. What effect will a smarter, more battle-hardened Luffy with unheard of skills make in this screwed up world? Should be fun to find out!
