Mark Casey, The Gemini

    At some point in his life, Mark Casey was once an ordinary guy with an ordinary job. Little did he know his seemingly ordinary life was only the beginning of the life of a legend. He is actually a warrior chosen by God to protect the Earth and all of its dimensions from demons and other evil beings. "The Legend of the Gemini" was a story passed down to everyone in Mark's family. The Legend foretold that someone in that family would be born with spectacular powers. The person would one day tap into his/her powers and have to face a twin sibling in battle. At that moment, the world would begin to fall into ruin and the warrior of legend (The Gemini) would have to spend the rest of his/her life battling the forces of evil and one day become immortal. It turns out that Mark was that warrior, and now he has spent 65 years fulfilling his destiny, with no end in sight.

    Mark is the strongest fighter in Earth Dimension 1. His power is rivaled only by his determination. His skill is an inherent fighting skill, which results in an irregular fighting style due to having no real training. This irregular style confuses opponents who expect to find counters to his attacks.

    In this story, Mark and his apprentice, Jim, have been battling giant robots from Dimension 2 that have attacked Neon City, killing people and taking their soul energy. Enraged, Mark and Jim make their way to Dimension 2 to end the attacks and find out the reasons for the horrible slaughter.
