Cubone.
Um... but the only way to get Marowack is to migrate it from LG/FR (Leaf Green/Fire Red, if so) or get a Cubone from a swarm by talking to Dawn's little sister and having the National Dex then evolve it! P.S. I hope I spelled Marowack right!
In the Safari Zone Desert Area, morning and afternoon only
go to lavender tower. work ur way up. then wen ur almost at top and bout to go up stairs it will say "get out... get out..."and marowack will appear. DO NOT WASTE YOUR POKEBALLS ON IT CAUSE IT DODGES BALL SO DO NOT USE, just defeat it.
Cubone evolves into Marowack at level 28 in ALL Pokemon games.
You need to enter the dungeon in the Marowack Dojo, presumably after you complete the other challenges.
After you beat Primal Dialga and Wigglytuff's graduation test, Go to Treasure Town. Then go to Marowack's dojo and you will see a cave to lead to Final Maze. Jirachi will be on 23F, Suicune on 31F and MOltres on 40F! No items allowed!
I don't know what tower you're talking about but I'f it's the ghost one you need the silph scope to see the ghost, It's a marowack but you cant capture it, because it's still a ghost but you can see it with silph scope.
after you get the fourth gym badge go to the game place that is controled by team rocket and go through it and at the end after you beat Geovini. You get the Sipho Scope. Next fly to Lavender Town and go in the big building, called the Pokemon tower, and after you fight the mother Marowack and beat some team Rocket, at the end a man takes you to his house and gives you a poke flute.
heres a good team: pikachu level 40 or higher with: thunder thunder bolt focus punch and iron tail charizard level 40 or higher with: flamethrower blast burn wing attack and fly snorlax level 40 or higher with: body slam hyper beam rollout and thunder hitmonlee level 40 or higher with: blaze kick hi jump kick mega kick and rock smash marowack level 40 or higher with:bone club boomerang hyper beam and focus energy and primape level 40 or higher with: cross chop focus punch hyper beam and low kick
First, you must defeat team rocket in Celadon and Saffron cities, and you will acquire the Silph Scope, which lets you identify the ghosts (Gastlys). When you go up the stairs on the last floor, you will battle a ghost Marowack. You cannot catch it-- many people have tried. You must defeat it in battle to put its soul to rest, then you may go into the final floor, which has numerous Rocket grunts. You must defeat each one until you get to Mr Fuji at the end. He will take you back to his house and you will acquire the Pokeflute, which lets you awaken the Snorlax that sleeps in the road. Hope I helped! :)
I have not figured that out yet, but, someone told me if you go through a different spot in Mt.Cornett you can catch a certain pokemon. Well, i found the exit, but a Galactic Grunt is there, blocking it. He says "Please pay no attention to the lowly grunt without any pokemon." The person who told me this said if you get there, you know through that spot, the old guy will be gone. Now I'm mad because the dumb grunt wont move!!!
