One Piece'sElbaf arc was always going to introduce fans to some incredibly overpowered Devil Fruits. In fact, given the fact that Elbaf is heavily based on Norse mythology, fans knew that a ton of Mythical Zoan abilities would show up here in one way or another. Oda also recognized the task at hand here and thankfully, delivered upon all expectations as he introduced some very powerful Mythical abilities at the very beginning of the arc, with more to follow soon enough.
