Pokémon FireRed and LeafGreen/Cape Brink

Now that you have rescued Lostelle, you can exit the Game Corner building. Make your way North and climb the flight of stairs. Proceed to climb the remaining stairs until you successfully make your way to the top of the hill. Enter the house and talk to the old woman. Make sure you have your starter pokemon as the first on your team if you wish to learn the move the woman teaches. If your starter is first in your team, she will recognize it and ask if you want to learn "The ultimate move". The move varies depending on which starter you chose. Charizard may learn Blast Burn, Venusaur learns Frenzy Plant, and Blastoise learns Hydro Cannon. The moves are a whopping 150 power points with 90 accuracy. The catch, your pokemon cannot move on the next turn, similar to Hyper Beam. Also, beware! The old woman only teaches your starter pokemon this move once, choose wisely! Traded starters can also learn their respective move (Stated above) even if you have already taught your starter a move, just so long as they are the required pokemon. That is about all there is to do on Cape Brink, minus the wild pokemon, so you may go ahead and leave. Afterwards, head back to the Game Corner and talk to the man you helped out earlier to give him that Meteorite you've been holding. Once that is completed, go ahead and sail back to one island and talk to Bill.
