In "Issue #11: "Lastikman Versus Babaeng Kidlat"" (Lastikman Versus Lightning Woman) (December 7, 1995), Lastikman's powers are mysteriously fading. To find out what the problem is, he examines himself in the laboratory of his secluded spaceship deep in the mountains of Sierra Madre. Meanwhile, a "cosmic spirit" comes to Earth and inhabits the body of a female mountaineer, becoming Thundra, the Lightning Woman. Swearing vengeance against Cosmo, the Space Gladiator who destroyed her previous body, she drains all the electricity in the vicinity, causing a massive blackout that affects even the power supply of Lastikman's ship.
