Magearna (マギアナ Magiana) is a steel/fairy-type Mythical Pokémon first revealed in a filtration of the magazine CoroCoro on February 10, 2016 and offically announced 5 days later. It's an Artificial Pokémon created by humans 500 years ago.
Magearna has a body made purely of steel, which was created by humans over 500 years ago. Magearna has a pair of long ears and a teal dot (resembling its nose), two pink eyes with yellow outlines, a teal sphere connecting its head with its body. It has two short arms, a skirt-like sphere body, decorated with yellow lines and two short legs. It is said that its machinery has a secret of some sort.
Magearna can transform itself into the shape of a Poke Ball when it sleeps or feels sad. Additionally, it can feel other Pokemon's feelings, thoughts and body conditions. When a Pokemon is wounded, it can sense its pain and will try all its best to help it.
