How do you evolve gligar into gliscor in Pokemon Red rescue team?

Answer 1

you give it a razor fang, give your gligar it to hold and level it up at night if you havent got a razor fang you can get them two ways. after completing the game go to snowpoint city and head south ask the sailor to go to battle area you will have to face your rival. once you have done that you go west until you find a way to get into the battle park. the two ways now is by heading east as soon you get there and it will be in a poke'ball or if you go to the battle tower earn 48 bp (battle points) go to the first big house half the size of the tower and ask the old ladies on one of the sides and ask for a razor fang.

Answer 2

After you beat the main game, the lombre guy will get you and say something about snub bull after a talk get gligar and give him the razor claw (I think) or level him up and go alone into the hole in whiscash pond. to go alone go to your home and your partner will ask you about the make other team leaders and all that. say yes ( you have no choice) go to the place where gligar is and go to team after recruiting him and get all people off you team and go as gligar. Hope I helped!!
