Target Avengers: Bizarre Adventures #1

The Avengers infiltrate an AIM base but are turned into big-brained chair-dependent monsters like their foe Modoc. With big brains and delusions of power, the new Avengers stop an attack by Attuma and also defeat the Leader and Abomination. Wolvie reverts to his human form thanks to his mutant healing factor and stops Modoc from making the new form of his allies permanent.
