There is one shadow Pokemon in Phenac City at the beginning. After journeying to Pyrite town, you will find that Cail, a rougue has a shadow Pokemon, and that the trainers in the town square (which is a circle on the pavement with trainers all around it) all have shadow Pokemon. Mirror B. also has a shadow Sudowoodo. The Under has a few trainers with shadow Pokemon, and also, Lady Venus has a shadow Suicune. Dakim of Mount battle has a shadow Entei, and Proffesser Ein of the Shadow Pokemon lab has a shadow Raiku. On Mount battle, many trainers have shadow Pokemon. Realgam Tower also offers many shadow Pokemon and the Deep Under offers 6-10 shadow Pokemon. The after- game area of Snagem Hideout has one of the starter Pokemon that you can catch and then Shadow Lab has the last starter Pokemon.
yes
Here are 2 lists. Serebii has a list of shadow pokemon, while Bulbapedia has the shadow pokemon and evolutions.
theres no shadow mightyena on Pokemon xd but there is a shadow pochyena
Shadow Rush is a move learned only by Shadow Pokemon in Colosseum and XD: Gale of Darkness that does 90 base damage (Colosseum)/55 base damage (XD: Gale of Darkness) and causes recoil to the user. It's super effective against all non-Shadow Pokemon.
No because it can't battle in the orre colosseum however every other colosseum it can enter and even has a shadow pokemon.
Purify all Shadow Pokemon. Then defeat all 100 trainers in Mt. Battle.
The final Colosseum is the Deep Colosseum after the Game, Pokemon here are Level 60-65, this is where you can catch the Pokemon you missed from the Admins earlier and a Shadow Shuckle.
You can't level up a Pokemon while it is a shadow Pokemon, but once you purify it, it will regain all the exp. points it would have received when it was a shadow Pokemon.
tyranitar i think
He has Metagross
In Pokémon Colosseum, there is nothing to do after the Deep Colosseum except to catch the remaining Shadow Pokémon so that you'll get to do battle with Fein, a Cipher Grunt who has copied your appearance and who also has a Shadow Pokémon, a Togetic. Defeat him and capture the Shadow Togetic and purify every Shadow Pokémon that you have in your possession and you have completed the game.
yes, you can, traded, or purifyed
