It's easy, to get to Master Greevil, use the elevator in the south west end near were you battled against Chiper Admin Eldes. In the north east end of the room, you'll find a max revive, just in case you need it douring the battle against Master Greevil. One more thing, make sure you have shadow salamance and that you snag shadow lugia, because you deffenely need those 2 for the battle, and he's TOUGHT, really.
Yes, you can. In fact, that's where I train my Pokemon when I don't train at Mt. Battle. And any shadow Pokemon you might have missed from him will still appear when you battle him again.
what is a greevil.
well you can do it the easy way or the hard way. easy way: get action replay and get the code for all dungeons and go to the last mystifing forest you see . hard way : This MAY work. beat the whole dungeon again and it takes you to him : P.S. it is Grand Master of All Things Bad! Don't listen to him. Just go to where Greevil is positioned which is at the top floor of Citadark Isle or the dome of the Cipher Headquarters where you fought Eldes, Ardos, Gorigan, and Snattle and you can battle Greevil again. He'll be waiting for you and all his Pokemon are at level 50.
before you go to master greevil's island you go with the professor to a hidden room in the first floor of the Pokemon HQ and he will give you one
Lugia is found in Citadark isle on top where u battle Greevil and catch it from him with a Master ball
snatch the one controlled by Grand Master Greevil (Mr. Verich) in the dome on Cytadark Isle.
Yes you can rematch greevil at anytime and he will still have his shadow Pokemon if you defeated them.
you cant get ho-oh, you have to trade him from the games Pokemon sapphire,emerald, or ruby to Pokemon xd. you're dumb to think you can get him from master greevil. he only has 4 legendaries: moltres,articuno,zapdos, & lugia. you can only catch lugia with a master ball, other pokeballs will not catch him. Actually, you can catch lugia with an ultra ball, but it's pretty tough. You're better off using the master ball, and leaving some room in your party so you can use him to help defeat master Greevil.
Defeat Master Greevil. When this is completed, you can trade from the Pokemon Center in Phenac City.
u must beat master greevil then beat him 10 more times then u go to agate villige then go into cave u find him
He will keep coming back, you cannot defeat him and he go away.
You have to go to Citadark Isle and go through it. At the end, you'll face Master Greevil (I think that's his name) and he has Shadow Zapdos, Moltres, Articuno, Lugia, Rhydon, Exeggutor and Tauros.
