Laplace

Laplace is the Wizard partner of Solo in Ryuusei no Rockman 3. According to the the game Laplace is the last EM-Body from Mu, awakened after Mu fell in to the ocean. It is unknown why Laplace specifically joined Solo. He either joined him because he understands Solo, or the fact that he is the last Murian alive. Because Solo can already Wave Change by himself, he doesn't perform Wave Change with him. Instead Solo uses Laplace's Wizard abilities. Laplace has the ability to change into a large sword, which can be used by Solo, either whilst in human form or as Rogue.
