Heron is an adult, male speed archaeopteryx living in the hollow mountain with the Hattori Clan and Masanari Black Flowers. He often serves as a mount to top agents of the MBF for transportation. His wings are a blue-grey color, while his underbelly is white and head is black. He prefers flying over oceans and is best for traveling across continents. When feeling threatened, he opens his wings wide and raises his neck in the air to deter threats.
- His name derives from the bird of the same name.
