Jonathan Storm (Alien Impostor) (Earth-88201)

This "Johnny Storm" was an alien of an unknown race who wanted to invade and conqueror the Earth. After the original Johnny Storm and his crew went into space they killed them and assumed their identity and returned as the Fantastic Four and acted like they had gained powers from the Cosmic Rays. Doctor Doom discovered the truth and attacked the foursome and was able to kill "Human Torch" by stabbing him with a Hafnium Carbide sword.^[1]
