Demak is one of the Dark Signers. He wears the black robes of the Dark Signers accented with gold stripes. He has great hatred towards the Signers. His dark mark is the monkey. He also happens to know Krieger.
When the powers of the Dark SignersMisty Lola and Carly Nagisa manifest at the same time, a Security wagon transporting Krieger is at the epicenter of the quake caused by their two Earthbound Gods. Demak appears and frees Krieger from their custody, displaying apparent superhuman strength (enough to break Krieger's handcuffs with a game card). It remains to be seen where this will lead.
