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.
you need to battle a trainer with shadow Pokemon, you will be able to "snag" it. it will only have one move and will not be able to level up until you have purified it. it will then learn moves. this is the only way to catch Pokemon in Pokemon colosseum.
pokemon do not evolve on pokemon colosseum
Yea
A solo run, which is what it sounds like you may be trying to do, of Colosseum is a bad idea - it's much harder than the main game series games and involves all double battles. I'd suggest purifying and training some shadow Pokemon up to Umbreon's level.
Yes in fact you can use any level Pokemon up to level 100 just make sure each Pokemon is that level.
drifloon,drifblim,
Deep Colosseum for Story Mode. This is where you'll have to battle in the 5 rounds to pick up a Shadow Pokemon named Shuckle. After that Togetic will be available to you by a Cipher Peon impersonating you. If you're in the Battle Mode, it's either Orre Colosseum or Realgam Tower but I haven't played much in the Battle Mode in a long time because I don't like their level restrictions and for the Story Mode, we have to train way higher if we want to succeed.
Gligar doesn't evolve in Pokemon Colosseum. His evolution, Gliscor, only debuted in the fourth generation of Pokemon games and Colosseum is a game from the third generation, so he is not available in it.
You level up your Pokemon in order to beat him. There is no speacial way. But you do have to use the master ball to capture tyranitar
you go and turn all you shadow poke'mon in to nermol poke'mon after that you go look for the unitment colosseum in the game. if you need more help put up a quisten for me and will do my best to help you with the game .
