Laplace

Laplace is the Wizard partner of Solo in Shooting Star Rockman 3. According to the the game Laplace is the last EM-Body from Mu, awakened after Mu fell in to the ocean. Because Solo can already Wave Change by himself, he doesn't perform Wave Change with him. Instead, Laplace transforms into Solo's new sword, which he can use both in human form and as Rogue. While Solo despises friendship, he makes an exception with Laplace, making Laplace his partner and only friend. Due to his attitude, he may, however, only view Laplace as a (literal) tool But due to story translation problems it is unknown. The reason Laplace is Solo's only friend may be that Laplace understands how Solo feels being the last Murian alive. Laplace doesn't like to talk much to anyone but Solo and also belives that he is superior to Omega-Xis. Since Rogue is the mega man starforce counterpart of Bass than Laplace is apperently the counterpart of Treble
