Spider Eagles (スパイダー イーグル, Supaidā īguru) are a beast species indigenous to Mt. Split-in-Half.
Spider Eagles build webbed nests deep within Mt. Split-in-Half's canyon in order to protect their eggs from predators, making their eggs one of the most difficult ingredients to obtain. They are also known as Dream eggs. The Mt. Split-in-Half canyon has updrafts that help hatched Spider Eagle chicks learn to fly.
- Spider Eagles are never seen in the manga or 2011 anime series, but are shown in the 1999 Anime adaptation.
