Catch a RALTS, can be found at the route beneath Solaceon Town. Train your RALTS to level 20 and it will evolve into KIRLIA. Train Kirlia to level 30 and congratulations! You'll now have a Gardevior! (P.S if your KIRLIA is a male, you could give it a dawn stone to evolve it to GALID)
Yes
Ralts will evolve in lv.20 to Kirlia and you must choose between two pokemons:Gaurdevoir or Galladeto make Gaurdevoir, you need to lv it up to lv.30 and it will evolve automaticallyto make Gallade, you need to use dawn stone (only male Kirlia can become Gallade)I personally suggest you make you Ralts into Gallade
You can not find a Gardevior on Emerald. You will have to find a Ralts in route 102 then evolve it into Kirlia at Level 20. Then into a Gardevior at level 30.
Gardevior deflects projectile attacks, such as Samus's Missile, and throwable items, such as Pokéballs.
no it can`t evolve
Lopunny, Gardevior, and Medicham (i think gardevior should get together with team raider's gallade)
you get a girl ralts or kirila
yes. go to victory road and cross the bridge, you go to the right, use rock climb (down), then go to the left and there will be a trainer. he has a haunter, a gengar, then a gardevior. hope that helped
you can't find a gardevior in the wild
The first Psychic you'll encounter has one.
Wally, the true rival of Pokemon ruby, sapphire and emerald.
you can migrate from saphire, or you can catch a ralts in the safari zone and evolve it
Yes
you have to get a ralts and level it up to 30. the first evolution is kirlia (at level 20)
