Eiichiro Oda

Eiichiro Oda might be best known for creating the world of the Grand Line with One Piece, and certainly with good reason, as the mangaka's work has been one of the most popular Shonen franchises to be released in the past few decades, but he definitely did work before we were introduced to the world of Luffy and his Straw Hats. In a one-shot titled Monsters, Oda created a unique world that didn't manage to pick up the same level of popularity as One Piece but will be re-released with a new voiced comic this fall.
