The Burning Ruins (Smash Wars)

The Burning Ruins starts out with many ruins covered in fir, ash, and lava. Mario and the others see the volcano and head for it. They all get attacked by many demons of different shape and size. The heroes and villians still go through though. They then fight the super demons which are blocking the main entrance to the gate.

They all still are able to defeat the demons and continue through. It shows a cutscene where Zorm is outraged and sends more demons to stop them.
