answer is that you cant catch gallade in pearl only way is to get kirlia from platinum/emerald after you defeat champion and use dawn stone and it evolves into gallade.
just get a MALE kirlia using a dawn stone.
Honestly, I think the best Pokemon in Pearl would have to be draginite,salamance,palkia,or magye even gallade.
You cannot get a Gallade on Pokemon Ruby. But you may get one in Pokemon Diamond or Pokemon Pearl. - Badminton
You cannot find wild Gallade in order to catch them in Pokémon Pearl however you can find wikld Ralts in Routes 203 and 204 and then you can raise it until it reaches Level 20 at which point it will evolve into Kirlia and then you can use a Dawn Stone on a male Kirlia in order to evolve it into Gallade, a female Kirlia can never evolve into Gallade, only male Kirlia can evolve into Gallade.
no gallade wasn't a Pokemon until gen IV (diamond and pearl)
You cannot get Gallade in Pokemon Emerald. He can only be obtained in Diamond and Pearl by evolving a male Kirlia via a Dawn Stone.
Use a Dawn Stone on a male Kirlia to make it evolve into a Gallade.
Why do you even watch Poke'mon? Ash is so annoying!
You can't catch a charizard in pokemon pearl.
NO you cant catch syther in Pokemon pearl
3 easy steps to get gallade are: 1:catch a ralts 2:get a dawn stone 3:evolve it to gallade hint:try this in any Pokemon online games and trust me you"ll get a gallade
neither of them is better, they are both the same, but in diamond, you catch dialga, and in pearl, you catch palkia, and you can catch different Pokemon in each game for example: you can catch this Pokemon in diamond, but not pearl but: you can catch this different Pokemon in pearl, but not diamond
