Ryu shi oh

Ryu Shi Oh, CEO of the enigmatic "Doogo" company behind that facade, however, lies a man hungry for vengeance against the Russian organized crime group that raised him. As a young boy, he was taught how to kill and serve the group, Pavel. Now that he is all grown up, Pavel holds him under their reign to distribute illegal drugs under the guise of Doogo. They even call him Anton, a name that he hates. But Shi-oh wants to break free of that group. And to do so, he needs to be more powerful than them. This is why he developed the drug, CTA 4885, along with an antidote that only the rich can afford. That's how he turned into a villain and his desire for power. So much so that he consumes the drug at will to become stronger than his enemies. Thankfully, he has the antidote so he can return to normal anytime he wishes.
