Addes is a powerful organization and the main antagonists of the Maximum Impact series; they have also sponsored the tournaments in those games.
The organization's origins are shrouded in mistery, although many of the members pride their inhuman (and possibly alien) nature. They possess mysterious and advanced technology and can change the course of the world within a mere instant. Through timely surgeries, the group's scientist's can also tweak the human body to possess superhuman abilities. They label these specimens as "Type X" ("X" being a variable for a single capital letter).
