Gardevoir

What are they used for in each phase?

Ralts: It has red horns on its head that act as psychic sensors. They allow it to perceive the emotions of humans and other Pokémon, immediately hiding if it detects negative energy or hostile intent.

Kirlia: Horns grow and spread across her head, amplifying her psychokinetic power. This allows her to distort space and foresee the future.

Gardevoir: It has red plates on its chest and back that form the shape of half a heart. These plates serve to materialize its feelings of loyalty, channeling its energy to protect its trainer at the cost of its own life, and even creating small black holes.

Gallade: It has sharp red protrusions on its chest and back. In addition to channeling its psychic power, they act as a defense and support mechanism on its body.

In compatible games, using Gardevoirite, it can Mega Evolve into Mega Gardevoir. This greatly increases its Special Attack and Defense, changing its ability to Pixilate (Normal-type attacks become Fairy-type and increase in power).

It's a natural special attacker. Its most outstanding stats are Special Attack and Special Defense, making it ideal for devastating moves like Moonblast or Psychic.

Synchronization: If Gardevoir is poisoned, paralyzed, or burned, the opposing Pokémon will also suffer that same status.
Trace: Copies the ability of the opposing Pokémon upon entering battle.
Telepathy (Hidden Ability): Avoids taking damage from attacks by his own allies in double battles.

Weaknesses: Poison, Steel, and Ghost
Resistances: Fighting and Psychic
Immunities: Dragon (thanks to its Fairy type)

Height: 1.6 m Weight: 48.4 kg
Evolution: Ralts → Kirlia (Lv. 20) → Gardevoir (Lv. 30)
Gender: 50% male, 50% female
