Gardevoir is a generation III Pokémon which makes its debut in Pokémon Ruby/Sapphire for the Gameboy Advance. It was originally just a Psychic-type Pokémon up until Pokémon X/Y where it became a Psychic/Fairy-type. It is one of two final forms of Ralts which can be obtained if Kirlia reaches level 30. In Pokémon X/Y Gardevoir can Mega Evolve into Mega Gardevoir if holding a Gardevoirite. These Pokémon can be both male and female, but I prefer to have mine female because of its feminine appearance and its male only counterpart, Gallade. There are no visible differences between genders.

Gardevoir's physical appearance looks something like a ghost or dancer. Its body is white with its hair, arms, and under skirt being green. It has a single pink horn on its chest and a smaller pink horn on its back. Its eyes are also pink. It has three spikes on each side of its head which appear like ears or horns and looks sort of like a mask. While some games and artwork appear to show Gardevoir without legs, merely appearing to be hovering wherever it goes, it actually has two white long and slender legs that hide under its skirt. The skirt flows down, touching the ground and appears to be longest in the back.

While Mega Evolved Gardevoir truly looks like a ballroom dancer. Its skirt is large and pure white, and on its face it looks like it's wearing a mask, and on its slender arms it looks like it's wearing gloves. It is absolutely gorgeous. Its green hair looks more fancy and curls up a bit around the sort of mask-looking ears/horns (I'm not exactly sure which they are), which have two large spikes near the top, while it has two smaller spikes on the bottom. The single horn on its chest splits into two, extending to the sides. It also looks just as gorgeous in battle.

When comparing Gardevoir's shiny form to its normal form there is a lot of noticeable differences. It actually looks pretty cool. The colors that are usually green are now a blue and the pink horn in its chest is now orange. Its eyes are also now orange. Shiny Mega Gardevoir looks amazing. Its arms and dress are black and its green hair is now a light blue. Its eyes and chest horn are same colors as its normal form.
