Eric Chanikov, also known as Dr. Chanikov, was a character from Impossible Creatures. He is the father of Rex Chance and colleague of Lucy Willing. He is best know for being the developer of the Sigma Technology, along with Nikola Tesla, while testing Tesla's "Death Ray" for the first time, which caused the big explosion of the Tunguska Event. Chanikov's wife died in the explosion and his son developed mutations that turned him into a creature-human hybrid, due to exposition to the radiation. Chanikov sent his son to the United States, with a trusted friend. Eric is killed by Upton Julius, who takes him captive first, in order to be able to experiment with Rex. Julius and Chanikov's collaborators continued working under Julius' orders.
