Ailurosa is an Espeon/Cofagrigus fusion that was created when a Yamask tried to posses an unfortunate Eevee right before it evolved. This event resulted in both Pokemon becoming permanently fused into one being, with it's new personality being a blend of the two originals.

This may have ended up being a boon however as they went on to become the lead of a mummy themed Jazz/Funk Fusion band.
