Markov is a Negative Number Holder, and the holder of Negative Number 16: Shock Servant. He was born when the shadows were unleashed. He is impetuous and impatient, rushing head long into things before thinkng about them. He challenged Michael to a duel while his own Number Senses were not yet clear, thinking Michale had Number 16. Michael defeated Markov and since he didn't have Number 16, he did not obtain Markov's Negative Number. Markov was then beat up by Shan, and then killed and sent back to the shadows by Negative Number 17: Balrog Dragon.
Markov play a typical Xyz Deck focusing on summoning his Negative Number.
