Reversal Mountain

Reversal Mountain is a mountain located in eastern Unova. It is connected to Undella Town from the east and to Lentimas Town from the west. The Strange House is just east of Lentimas Town on the exterior of the mountain. Inside the mountain, Bianca will join the player as a Multi Battle partner. Reversal Mountain was where Heatran used to come to cool off. If the player finds and brings the Magma Stone to the mountain's lowest floor, Heatran will appear.
