UMA

UMA (Unidentified Mysterious Animal) are ancient EM Beings of the mythical continent Mu based on cryptids. They are created by the EM Wave God - Le Mu, which can create endless amount of the UMAs. In Mega Man Star Force 2, the UMAs are used by Lady Vega, aside from Laplace, who is Solo's Wizard and issued by Hyde when he gives a certain person an Ancient Star Carrier. Most of the UMA were guardians of the continent Mu before it's fall.

Trivia

 * Besides humans, UMAs can also use EM Wave Change with Murians.
 * Apollo Flame is also a creation of Le Mu, however he was based on a Greek deity, not an ancient animal, therefore he isn't in the list. However Laplace is still counted.
 * It is unknown if Le Mu could manipulate Laplace and Apollo Flame, since they're both Mu EM beings awakened after its destruction.
