Onboard the SHIELD Helicarrier, Earth's Mightiest Heroes test a new metal alloy called adamantium! The metal is so strong that even Thor's hammer cannot fracture it! Wow, what would happen if this awesome alloy fell into the wrong hands? Regrettably the Avengers don't have to wait long for the answer as the Vision steals the adamantium and then ambushes his fellow avengers inside the mansion! What a shocking development! Could things get any worse? Perhaps only if the Vision's robotic creator were to suddenly appear! An excellent issue! Cameo appearance by Ultron-6.
This is the first of the five issues that Barry Windsor-Smith drew for the Avengers title (1st series): issues 66, 67, 98, 99, and 100.
