The Incredible Hulk #308

Direct

At the dimensional crossroads, the Puffball collective gives the Hulk a sob story about the destruction of their homeworld. Hulk rips down the mystic barrier allowing the Puffball collective to return home but discovers that he has been duped into freeing a horde of N'Garai demons on the multiverse. With a little help from Goblin, Guardian and Glow, Hulk is able to re-close the doorway, trapping the Puffballs and the demons inside.
