Is One Piece a Rip Off of Guardians of the Galaxy

Not trying to flame at all, and I up until now thought Oda was a genius...



I just saw Guardians yesterday and the whole thing felt like One Piece in Space



The characters of guardians are like one piece, Star Lord is like Luffy, even his personality and backstory, Gomorra is like Nami, Groot is like chopper, and rocket is like Ussop...



Is manga just a rip off of American comics, please calm me down guys, even the comedy was like a chapter of one piece, especially the end fight scene
