Doctor Doom made an appearance in Marvel UK's Combat Colin strip. A superheroes convention is attacked by the robotic Steamroller Man. After Combat Colin and his sidekick Semi-Automatic Steve defeats the robot, its controller is revealed to be Doctor Doom, who explains that after years of being defeated by American superheroes he thought (wrongly) he could stand a chance against some incompetent Brits. The final panel shows Doom back in his lair, surrounded by newspaper cuttings detailing his past defeats and wondering how he would do in a fight with Thomas the Tank Engine.
