Sapphire shows Wattson and Coil-Boy the entrance to New Mauville. Before they can enter, four little boys run up and challenge Wattson to a gym battle, causing Sapphire to realize that Wattson is the gym leader of Mauville City. Wattson's Electrike and two Magnemites defeat the boys easily, making them crestfallen, but Wattson gives them the Dynamo Badge anyway, impressed by their enthusiasm.He offers Sapphire a badge as well, for finding New Mauville. Sapphire is insulted and slaps his hand away, saying that she needs to fight for it. The badge flies from Wattson's hand and hits the rogue Donphan, angering him, and he chases them. They fall into New Mauville, where Wattson is separated from the others. Coil-Boy explains the history of New Mauville to Sapphire, telling her it had been built by their ancestors so that there was room for children to play.
Touched by the righteousness of their cause, Sapphire offers to help on the condition that Wattson have a gym battle with her afterwards. Wattson agrees from the darkness and his Electrike leads Sapphire and Coil-Boy to where Wattson is stuck to a haywire generator.
