Iono Feria(イオノ フェリア) (also translated as Ion-Faeria and Iona Faria) are a large flying creature found on Zebes. They resemble "butterflies" and are referred to as such by Samus, though their bodies are slightly like those of bears. She encountered her first one when it drank from her water container, accidently scaring Pyonchi. They are from the Metroid Manga. It is possible they may have been driven to extinction either by the Space Pirates, the introduction of Flesh-Eating Bacteria with the arrival of Zoomers, or with the destruction of Zebes.
