Warning: Contains spoilers for One Piece chapter 1073.One Piece chapter 1073 is out, and it drops a huge clue about Nika that could change everything about him. While Nika was first mentioned in the Wano arc, he was quickly established as one of the most important characters in the series. In addition to being the first actual god in the series, the fact that the World Government has gone to incredible lengths to erase proof of his existence sets him up as one of their biggest threats. That idea is further emphasized by how the Gum-Gum Fruit, really the Human-Human Fruit, Model: Nika, was eaten by both Luffy and the equally enigmatic Joy Boy.
