Yea
pokemon do not evolve on pokemon colosseum
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.
Yes in fact you can use any level Pokemon up to level 100 just make sure each Pokemon is that level.
Pokemon evolve when you level them up to a certain level, by trading them, by friendship, or by using stones.
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
Haunter can level up and evolve. It evolves by trading with another player.
it doesn't matter
In Pokémon Colosseum, Swablu evolves into Altaria when it reaches level 35. Players need to train their Swablu to this level to trigger the evolution. It does not require any special items or conditions beyond leveling up.
Yes you can, but first beat leafgreen and deliver the ruby and sapphire to celio then beat Pokemon colosseum, BUT you need a GBA to GCN cable to do this: Go to phenac city after beating colosseum and go downstairs in the Pokemon center talk to the lady after getting the Pokemon you want to trade from the PC. Next hook up the GBA to GCN cable to gamecube socket 2 and hook it up to your GBA(GBASP works too) then on leafgreen save your game in any Pokemon center with the Pokemon you want to trade after saving turn it off and return it on and wait for the connection to be made then start trading, to trade use the gamecube controller to choose the colosseum Pokemon your trading then say ok then using the GBA's Dpad choose your Pokemon from leafgreen then press A and confirm your choice by pressing A again and the trade begins! Happy trading!
give it the razor claw and level it up gligar evolves if you give him the razor fang and level him up at knight hope i helped
