Where is the gym leader of sootopolis city?

Answer 1

if this is for blue you have to beat team aqua in their under water cave on route 128 use dive in the underwater trench then find a cave with a sub in it dive up in the cave then solve the mazes[ wich is pretty hard u need surf, strength and rock smash.]then after u beat the boss kyrogre dissapears then go to the cave in sootipolis[u will notice the old man is gone.]and go in. battle kyogre[ but don't actullay hurt it at all.]then use the master ball first thing.[it never fails!:)]then go to the gym. the gym is tricky. the trick is to not step one the same peice of ice twice. if you do you fall and have to battle a bunch of chicks.[ i mean like girls not really chicks]. your welcome! :):):):):):):):):):):):):):):):)::):::):):):):)
