Gallade somewhat shares a resemblance to its female counterpart Gardevoir, but is different in many ways. The "skirt" of its pre-evolved form is now gone, revealing its legs, which are now much wider. The red horns that were on its head have moved down to its chest, like that of Gardevoir, but are much sharper. Its head is also similar to that of a Gardevoir, but it instead has a large gray-blue horn resembling a gladiator helmet. Another notable feature is the blade-like protrusions from its elbows, which Gallade can use as swords. It seems that the sharp protrusions can be extended and retracted when necessary. The shiny version of Gallade has a blue coloring where the original has green, and its "helmet" becomes silver instead of light blue. It also has a slightly purple colored hue.
Gallade have the ability Steadfast, which allows its speed to increase x1.5 if it flinches. As Mega Gallade, it has Inner Focus, which makes any move that attempts to flinch Mega Gallade, such as Fake Out, completely useless.
Gallade evolves from a male Kirlia by the use of a Dawn Stone, but a male Kirlia can also evolve into Gardevoir at Level 30. It can further evolve into Mega Gallade with its Mega Stone.
Gallade made its anime debut in "A Grand Fight for Winning", and it made an appearance in the movie The Rise of Darkrai. Zoey also has a Gallade, which she used in her Grand Festival match against Dawn.
His arms might be samurai swords due to how they look and how Gallade uses them.
In his cry, it sounds as if Gallade is drawing out its blades.
The name "Gallade" has actually existed long before the Pokémon's creation; there is a U.S.-based chemical distribution company called "Gallade Chemical", which started business in the 1960s and has no relations with Nintendo or The Pokémon Company International.
Gallade is one of the two Fighting-type Pokémon that can learn an actual Fairy-type move, which is Dazzling Gleam, the other is Meloetta in its Pirouette Forme, but only in battle after using Relic Song.
Gallade's English name is a combination of the words "Gallant" and "Blade". Its Japanese name, Erlade, is a combination of the word "Earl" (meaning chieftain) and "blade".
