The Flame Thrower is the third mini-boss and the first to have a different theme.
The Flame Thrower will at first slowly walk around the room, using his massive arms to attack when close, and tossing fireballs when far away. After enough damage, he will charge around, flailing his arms around, tossing flames, and breathing streams of fire. Occasionally, he will stop to create an explosion. His theme is Followers of Darkness -The Second-, and he has 3900 HP.
