Super Eagle Thunderbird was the Piasa Beast King and terrorized air, sea, and land. That all changed when he was given a magic thunderbolt by Sosthenes Vajran, the firstborn of the Overwinning. Now he is a hot blooded henshin superhero. He has an elemental wind punch and the oversight. He forms a battle couple with Chai Overwinning; together they fight their family, the Beast Kings who rule Xibalba and are omnicidal maniacs that seek to remake all of creation.
