"Stranger in a Strange Man!"
The Wasp is rushed to the hospital following an attack on the group by the Stranger who had come seeking the Scarlet Witch. Wanting revenge, Yellowjacket takes a team of Avengers to try and find the Stranger before he can attack again, or find the location of Vision and the Scarlet Witch who are off on a honeymoon.
Taking the fight to the Stranger, the group finds the Stranger's inconsistent abilities a mystery until their final confrontation aboard the Strangers ship where, thanks to the Beasts ingenuity, is revealed not to be the Stranger at all, but the Toad in disguise. Easily defeating the Toad, the Avengers learn that following Toad's last encounter with the Avengers, he traveled back to the Strangers world and stole technology in order to get back at the Scarlet Witch for turning down his advances and never being interested in him.
