In the StarCraft II: Wings of Liberty mission, "The Devil's Playground", which takes place on Redstone III, there is a dancing Diablo miniature (called Diablo, Lord of Terror) on one of the periodically lava-flooded islands in the southeast. He is unaffected by the lava. Diablo is not normally selectable and cannot be directly interacted with.
