Obtain the Silph Scope and defeat it in battle.
you can just keep goin it isn't to hard to see don't try to catch marowak it knocks em away
In FR? Marowak. It's the thing stopping you... At the real top it's team rocket.
First you need the silph scope which is obtained in the rocket game corner, when your in the tower you only need to keep going up until a marowak ghost stops you defeat marowak then go up now your on the top floor defeat team rocket then talk to mr fuji.
You can catch marowak in the Pokemon Tower (with all the graves) yet they are quite rare. You can also evolve cubone. The Marowak that blocks entry to the top floor is uncatchable, and even a masterball (only obtained by hacking at that stage of the game) will fail.
Get the Silph Scope from the Celadon Rocket Hideout, then ascend to the top of the Pokemon Tower. Then, you'll be able to identify Marowak and defeat it to lay it to rest.
The Pokemon is marowak and you need the silph scope to see it.Good luck and hope I helped!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
well it is a tower like a grave, it has plenty of gravestones, and Pokemon trainers. you find ghastly, haunter cubone and 1 marowak. you battle team rocket at the top and you rescue dr fuji.
Silph Scope can be used to identify the unknown wild ghosts in Pokemon Tower at Lavender Town. Normally, the tower can be accessed without it, but one ghost (later identified as an uncatchable Marowak at Level 30) does not allow you to reach the top floor. With the Silph Scope, defeat the identified Marowak and save the old man (Mr. Fuji) on the top floor from some Rocket Grunts.
Go to the Pokemon Tower in Lavender Town. Fight off ghosts until you get to the top. You'll find the ghost of Marowak.
you will get Gastly, hunter and the gost is a Marowak.
I'm going to assume that you're asking why you can't see the Pokemon in the Pokemon tower. First of all, you must obtain the Silph Scope to reveal that the Pokemon in the tower are Gastly, Haunter, and Cubone. The Pokemon at the top who keeps turning you away is the ghost of Cubone's mother, Marowak. You can't catch her, so don't waste Pokeballs on her (after all, she is a ghost).
You cannot catch it without cheat codes because the Marowak is a scripted special Pokemon "ghost." If you really want a Marowak, you can get one by evolving a cubone or catching one on Victory Road.
