“Hellfire Across the World!”
Gerry Conway, writer * John Buscema, artist * Mike Esposito, inker * Artie Simek, letterer, P. Goldberg, colorist * Roy Thomas, editor
Thor and Hercules travel deep within the Underworld, but Pluto teleports away, along with Krista, who has gone mute with trauma. After Pluto flees, Thor uses Mjolnir to teleport himself and his friend to Asgard, in order to ask Odin to find their quarry.
Where did Thor suddenly gain the ability to teleport? Again, lacking a better explanation, it seems likely that this is a newer power granted by the re-enchantment of Mjolnir way back in issue #151.
At any rate, Thor and Hercules ask Odin where Pluto is. Odin searches for Pluto and discovers that the Lord of the Underworld is in Manhattan. It is unclear what Pluto was doing on Midgard, but he sees no reason to stay and fight now that his plan has been undone. He leaves, but not before taunting Thor for being so quick to mistrust his so-called friends.
With Pluto gone, Thor retrieves Krista. Unfortunately, she is dying for some unknown reason.
