Darkorus

Darkorus is a Dark/Flying-type Legendary Pokémon created by ★VS★. She is not known to evolve into or from any other Pokémon, and is the creator of the sky trio. Darkorus created the sky trio after she was betrayed by Thundurus. Legends say that she and Thundurus were in a romance hundreds of years ago. Thundurus left Darkorus to join Landorus and Tornadus to make the kami trio. Furious, Darkorus created Rainorus, Blizzurus, and Sunorus to make the sky trio. She planned to have a battle between the sky trio and the kami trio, but the battle never happened. Darkorus can be found during thunderstorms late at night. By flying around in a circle, she can make strong twisters and windstorms occur. She is also able to release dark aura through the cloud at the lower part of her body. Despite her fury in the legend she was in, Darkorus is known to be kind to people and Pokémon.
