Dialga doesn't even come into play until Pokemon pearl.AnswerDialga cannot be caught in Pokemon Ruby or Sapphire. It can only be caught in Pokemon Diamond or traded to Pokemon Pearl. Pokemon such as Lucario, Palkia, Darkrai are also exclusive to those two versions. The only Pokemon that may be caught in Pokemon Ruby are the Pokemon in the Hoenn Pokedex and Pokemon from Kanto and Johto generations may be traded from FireRed, LeafGreen and Emerald.
If you mean her starter then it was Torchic and if you mean the first Pokemon she actually caught then it was wurmple.
I don't think you can sorry :( Mewtwo; yet another legendary Pokemon that cannot be caught in Pokemon Ranger. Try as you may, it cannot be caught in that game.
Tornadus cannot be caught in Pokemon white. He can only be caught in Pokemon Black, in the same way Thundurus is caught in Pokemon White.
Besides the Torchic that was given to her, she caught a Wurmple in episode 288 (AG-014), "All in a Day's Wurmple"
It's called Pokerus, not poke-rush. Anyway, the way to get it is sheer luck. Random Pokemon in the wild may have Pokerus. By either defeating it or catching it, your Pokemon (unless if you caught it) will have pokerus. If you caught it, the infected Pokemon will still have it. I assume you already know what it does, and this is where I end my answer.
Pokemon Sapphire features a cave location called Meteor Falls where unique Pokemon may be caught. It is located west of Fallarbor Town.
It means that you almost caught the Pokemon. It says that when you have two shakes.
The Trophy Garden in Pokemon Diamond is located behind the Pokemon Mansion on Route 212. Many rare Pokemon may be encountered and caught only in the Trophy Garden.
It can be caught in Pokemon blue/red/ and yellow.
