Fernandez (魔界大帝フェルナンデス, Great Emperor of The Demon World Fernandeath) is the final boss from Waku Waku 7.
A powerful demon who seeks nothing but destruction, Fernandez was imprisoned by the power of the seven Waku Waku balls. Once the player character collects all seven balls by defeating the other characters, the seal upon Fernandez is broken, and he starts his rampage again, growing into a gigantic size. The fairy who watches the seal then makes the player character gigantic as well to fight Fernandez. Once he is defeated he is once again sealed.
Fernandez appears as a huge black ball with tiny bat wings and paws, having a cartoonish face with a big smile. His attacks involve extending his paws into various shapes, which give him a lot of range and have a high priority.
