Plot

Avengers are vanishing one after another with no end in sight! Is someone collecting super-heroes? In an attempt to replenish the roster, Iron Man brings in the Black Panther, Black Widow, Hercules, and Captain Marvel to help. But to no avail as T'challa, the Scarlet Witch, Wonder Man, and Yellowjacket all disappear from the mansion next! So the Avengers are down to their final four...Hawkeye, Iron Man, Thor, and the Wasp. Is that going to be enough against an elder of the universe? Meanwhile, Michael (aka Korvac) continues his preparations for conquering the cosmos. (mycomicshop.com)
