Sub-Mariner#14(1969)

Namor investigates unnatural volcanic activity and is attacked by the Human Torch. Namor soon learns that the Human Torch is under the Mad Thinker's control, but the Torch's struggle to resist the order to kill Namor gives the Atlantean the chance to reach the sea and regain his full power, after which he quickly defeats the Torch, inadvertently freeing him from the Thinker's control. After talking, the pair agree to team up against the Thinker. While this has been happening, the Thinker, the Puppet Master and Egghead have begun their scheme to conquer the United States by testing their ability to cut off all power to areas of their choice. They use their devices to create a giant energy-absorbing arc that prevents any electrical or mechanical apparatus beneath it from functioning for one minute, cutting off power to much of the nation. Egghead uses that time to broadcast a warning that, within the hour, he will dictate his terms for not similarly affecting the entire nation. Many costumed and non-costumed individuals are shown to be both alarmed by this threat but helpless before it. The Human Torch and Namor travel to the dormant volcanic island where the Thinker's headquarters is located. The Torch burns an opening into the stronghold but the Thinker had been expecting them and defends himself. Namor tries to destroy the machine that is vital to the villains' plan but not before the Thinker's ray causes the Torch to begin overheating beyond his control. Namor smashes the weapon that caused the overheating and knocks out the Thinker, but then has to use a piece of asbestos-lined metal to scoop up the Torch so he can use his now white-hot form to burn through a wall so that both of them can reach the sea. With his flames doused and his hair no longer blond, the Torch regains his memory and reveals that he's actually Toro, the real Torch's former partner, who was kidnapped by the Thinker while attending funeral for the Torch, and then brainwashed into believing that he was both the Torch and the Thinker's android slave. Enraged by this and the certainty that the Thinker played a part in the real Torch's death, Toro vows vengeance just as the Thinker is spotted escaping in his air-ship. The two heroes attack the vessel, with Toro flying ahead and into its rocket tubes where he uses his flaming body to propel the air-ship into the Thinker's laboratory, causing an explosion that destroys the skycraft, the laboratory and himself. Hours later, as the Sub-Mariner surveys the streams of lava that now cover the vanished island, he muses aloud about how Toro had laid down his life to avenge a friend.
