Magearna is a metallic, bipedal, and artificial Pokémon primarily composed of spheres. Its head is a medium-sized sphere with a slight point at the back. Around Magearna's head is a gear with seven teeth, though it does not cover its chin. It has two large, rabbit-like ears with gold rims; a tiny nose and mouth; and light red eyes with pinkish ovals in the center. Within these ovals are white crosses, and thin gold wiring encircles each eye with two small prongs resembling eyelashes. The rabbit-like ears appear to be two halves of a large disc connected by a hinge at the top.
Magearna's upper body resembles a Poké Ball: it is divided into two light blue portions by a thick gray band. In the front center of the band is a circular depression that is half-blue and half-pink. Above and below this depression, in the light blue portions, are yellow, diamond-shaped markings. On either side of its upper body are large, spherical shoulders with thin upper arms leading to large, claw-shaped forearms and slightly pointed hands. Its lower body is a much larger sphere that looks like a ball gown. There are golden, wavy lines on each side of this sphere, which is divided down the front and back by a gray line. At the back, there is a solid gold ring with a hole in the center at the bottom of this line. The front has a similar gold ring but broken at the top and bottom, with a shield shape in the center. Metal plates, akin to dress ruffles, adorn the bottom of its lower body. It has two pointed legs.
Magearna was created by a scientist 500 years ago. The sphere in this Pokémon's chest is known as the Soul-Heart, created by collecting life energy from other Pokémon. The Soul-Heart is Magearna's true body. Due to its ability to feel others' pain, it tries hard to save injured Pokémon. It can also perceive the emotions, thoughts, or feelings of other Pokémon. When sleeping or sometimes when sad, Magearna can take on the appearance of a Poké Ball.
When it was first invented, Magearna's body was mainly painted gold, though a lighter shade than the highlights and rims adorning its body. The ears and the top half of its lower body were painted red, matching the coloration of an ordinary Poké Ball. This vivid coloring indicates it was a gift to royalty. The princess of the land was very pleased with it.
Forms
