Combustion Man

Combustion Man, also known as Sparky-Sparky Boom Man, was an assassin with a unique ability to issue explosive force beams from a forehead tattoo. After a childhood injury, he replaced lost limbs with prosthetics. He is a silent, persistent tracker who proved a formidable foe to the Avatar and his friends. His primary weakness is his tattoo, which can cause his bending to backfire.
