Mark

The leader of a small time street gang that resides in the southern section of Titan city. Rival gangs have frequently attempted to invade on their territory but were fended off each time by Mark and his crew. Because of this, Mark has earned a reputation for being one of the most ruthless fighters in Titan city, this aided by the fact that he hardly ever lost a fight. One of the few people that have actually beat him was Rio Mendoza, another well known scrapper that also lives in the southern section of Titan city.

Mark and Rio have crossed paths many times and after each encounter, a rivalry has formed between them. As time went on and after countless bouts, what started off as a bitter rivalry, they have somehow became friends and now only spar with each other for the fun of it.

Mark's preferred fighting style is wrestling. A little known fact is that he learned everything he knows from his uncle who used to be a professional wrestler. Although Mark's moves and throws are similar to his uncle's, he has taken the time to come up with his own moves, his favorite being his finisher which he likes to call the "Armageddon Slam".

Around the time Rio went missing, Mark and his crew decided to search the entire city hoping to find him or at least learn of his whereabouts. This has lead him into the territory of rival gangs and has ended up in several close calls but he was more than willing to take the risk if it meant finding out what happened to his friend.

After hearing about Rio's return, he was ecstatic but not too long after, another incident occurred in which Rio's younger brother Toran was kidnapped by a hooded man who claims to be related to Rio's disappearance and threatened him to participate in the upcoming Berserk Fist tournament if he wanted to see his brother again. Mark has heard many shady rumors about the tournament, so he decides to enter as well to help Rio save his brother and to see if all the rumors he heard are true.
