Leonidus

Leonidus is a Pokémon that was created by Team Rocket mixing Articuno's DNA with a Rapidash. He is first introduced in Chapter 11 of Stun II. He is described as having, "the body of a Rapidash, but he was blue with blue 'flames' running across his body. He also had two blue wings that erupted from his shoulders, and a tail like Articuno's."

Leonidus was created alongside Thunder, and considered her to be his best friend. After escaping the Team Rocket hideout in which they were both held, unknown circumstances caused them to separate.

He has demonstrated the ability to move extremely quickly and to cause the air to get colder when upset. He is not known for speaking much.
