Curtis Jackson was the founder of The Invaders- a taskforce of enhanced individuals who fought in Europe during World War One.
Curtis' face was strewn with wrinkles, and he had slicked back gray hair. He was a no-nonsense man and always looked like it too.
Upon researching of the Central Powers' powerful and horrible biological gasses and agents, SSR researcher, Curtis Jackson, sought military permission to create a taskforce of enhanced individuals from Allied nations. He was successful, and his team of "Invaders" consisted of John Walker, James Montgomery Falsworth, Robert Frank, Lamar Hopkins, and the Human Torch. In the field, they were helped by Orson Rend'ul, Jim Hammond, Jack Fury, George Bailey, and Karl Kaufman. Their main target was Heinrich Zemo and Adolph von Rantenraven.
