Laplace

Laplace is the Wizard partner of Solo/Rogue in MegaMan Starforce 3. According to the the game Laplace is the last EM Being from Le Mu, awakened after the continent Mu fell in to the ocean. He is unregistered under Project TC, while Solo/Rogue is registered as No. 002.

Because Solo/Rogue can already EM Wave Change by himself, he doesn't perform Wave Change with Laplace; instead, Laplace transforms into his sword, which he can use in both human and Wave Changed forms. This replaces his sword from the previous version, which he pulled from his left arm.

Game History
Very little is revealed about Laplace, other than his origins as the last EM Being from Mu. When Geo Stelar and his friends first see Solo in the third game, Laplace is already his partner. This lasts throughout the game, where Laplace is inseperable from Solo/Rogue, and where he is always pulled out at the beginning of a battle.

Just before MegaMan enters the Black Hole Server, he is challenged by Rogue to a fight to decide who will go fater Sirius. It is revealed then by MegaMan that while Solo rejects all bonds with humans, he feels a deep connection to his own culture, and Laplace along with it. This is why Solo has formed such a close partnership despite his normal attitudes towards companions, and proves that he sees Laplace as much more than just a tool.

Trivia
