Avengers Vol.1 #55

$65.00

One of the legendary issues of the Avengers! As Earth's Mightiest Heroes battle their greatest foe for the first time! But at this point, they don't know who or what Ultron-5 is! The four avengers are still reeling from Jarvis' betrayal, the Masters of Evil's victory, and the Crimson Cowl's identity! However Ultron doesn't care about the Avengers' confusion! Because he's just loaded them inside a hydrogen bomb... and set the bomb on a collision course with the Empire State Building! Oh my, this looks like curtains for Earth's Mightiest! Unless the resourceful Black Knight and remorseful Edwin Jarvis can think of something quick!
