I returned to One Island to pick up a Pokemon that knew the move Strength, and then I returned to Mt. Ember to challenge the Moltres at its summit. I got there and I pushed all the boulders aside. I then went inside of the volcanic cave and I ran around, battling Pokemon and looking for the exit. I captured a Machoke and then I went outside. I pushed some more boudlers out of the way and I arrived at the top of the volcano. I challenged Moltres, and it was a tough match. It didn't want to be captured, but I managed to snag it after putting it to sleep. I used 14 Ultra Balls, but things weren't so bad. I flew back to One Island, healed at the local Pokemon Center and saved before going to Two Island.
