The Mountainside Temple is one of two default stages that comes with an official MUGEN download. It is the secret hideout of Suave Dude and Kung Fu Man's home stage. Kung Fu Man sets out on a journey to come here to save his girlfriend who was kidnapped by Suave Dude. In Evil Kung Fu Man's opening, it was featured as the destination where Kung Fu Man was searching for Suave Dude and was repelled by his evil clone.
The stage features in the mountainous place inside the Asian temple made of wood.
