Roger Gol D.

Gold Roger (real name later revealed to be Gol D. Roger) was the Pirate King, the strongest pirate alive, and owner of the legendary treasure known as One Piece. Born in Loguetown, Roger was famed as the man who did what no one thought possible — he conquered the Grand Line. Even before setting out, he was the only man who truly did not fear the dangers of the Grand Line and was even excited about venturing out there. Even with warnings about ships never returning from that ocean, he did not care; in fact, he even declared that was the reason for him going. He was said to be completely fearless, and those who witnessed his execution even claim that he grinned just before his death. Many people who've met Monkey D. Luffy and knew Roger have commented that the two are very similar.
