The Thermonuclear smoke devil is the boss version of the Smoke devil. These require a minimum of 93 Slayer to kill. Located at the Stronghold Slayer Cave, the thermonuclear smoke devil can only be attacked on a smoke devil task. The only exception to this is the Western Provinces diary, where one must be killed to complete a task.

This monster is the only monster to drop the Smoke battlestaff and the pet smoke devil. Their non-boss variants, however, also drop the Occult necklace.

Unlike most monsters in the Stronghold Slayer Cave, a dwarf multicannon cannot be used inside the boss room. If attempted, the cannon will be destroyed (similar to areas like at KBD or KQ).
