Gennady Gravilov was a bright student, but had a habit of taking and hiding items. He was almost expelled from school for taking batteries. Gennady also spent most of his time on the Internet messaging a "cajun angel." While working at Moscow State University, transporting boxes of paperworks from warehouses, Gennady came across a helmet from a prototype Crimson Dynamo armor made by the late Anton Vanko. He accidentally triggered the armor's activation via the helmet's remote control and homing mode. The armor went on a rampage throughout Russia in its attempt to get itself to the helmet while Gennady initial believed the helmet to be a virtual reality gaming system. Gennady learned from Vanko's notes that the armor builds an massive electromagnetic charge. Without special gauntlets, it would overload. Gennady was pursued by the rogue spy Alexandre Deveraux as well as the russian military who were all after the armor. With the help of Wayne Jennings, an arms inspector, Gennady was able to stop the armor. Anthony Stark offered his technical assistance if needed. Gennady managed to escape from the military with the armor via a railway using the armors maglev system. Gennady then hid the armor in basement of his stepfather's warehouse, stating an intention to become a superhero and unaware that Tony Stark still maintained a remote kill switch for the armor should he ever decide to shut Gennady down. - Marvel Database
