Ornis

Orson is a character of the day who appeared in A Relay in the Sky!.

Orson entered the Pokémon Sky Relay to retain his title as the defending winner. He entered with his male Starly, Staravia, and Staraptor. During the competition, he had his Pokémon stay mostly in second position.

By the third leg, only Orson's Starly and Ash's Noibat were in the running following Team Rocket's sabotage attempts. The Pokémon passed through a valley with strong wind currents, and while Noibat was blown away, Orson and Starly were fully prepared for this. Orson had Starly fold his wings, so that he could nosedive through the valley. Noibat was able to recover however, and a head-to-head race to the finish unfolded between him and Starly. Starly was ultimately victorious as he finished by a noselength, giving Orson the win.
