The UMAs are revealed to be the ancient EM Beings of the mythical continent Mu, therefore their creation are based on mythical or ancient creatures and deities. Most of the UMA were guardians of the continent Mu before it's fall, such as Condor was a protector of the skies around Mu. They are all created by the EM Wave God - Le Mu, which can create endless amount of the UMAs. The UMA are used by Lady Vega, aside from Laplace, who is Solo's Wizard.
