Thor
has leapt into a troll furnace to recover his hammer Mjolnir and has only a few
seconds before he returns to his Don Blake form, which would kill him. He
locates the hammer and pries it free from the magnetized slab and returns to
the cave, only to find it deserted, the trolls having massed to attack Midgard.
He is approached by the troll Queen Ulla, who had called out to save him during
his battle with Ulik. She is distraught, having brought shame to her husband,
allowing Ulik to gain control of the troll army. She directs him to a tunnel
leading to the surface…
…where
the troll legion under the command of Ulik breaks through with their war
machine, destroying buildings and terrifying the populace. Meanwhile, Thor has
become lost in the cavern tunnels so he begins making his own. And in the
throne room, King Geirrodur dismisses the two guards who call Ulla’s action
treasonous and confesses that if Ulik’s invasion is victorious, his reign is
over. The King and Queen sit down and share their misery….
Ulik
and his trolls fight the New York police, gaining the upper hand as Ulik hurls
an eighteen-wheeler at his foes. At Avengers Mansion, Jarvis informs the
Warriors Three about the battle downtown and they decide they needs some
excitement and head out. Thor emerges from the tunnel and it is captured on
television where Silas Grant and Tana Nile see it so they decide to go to his
aid, Tana resuming her Rigellian form. Thor battle the trolls; stopping to keep
a large inhabited building from toppling, he is at the mercy of his foe but his
comrades arrive to hold off the enemy and Tana employs her stasis gun on Ulik
but it doesn’t not stop him. It does, however, weaken him so that Thor can beat
him unconscious. The other trolls, seeing their leader fallen, panic and
retreat underground, taking Ulik with them. Thor topples an abandoned building
into the tunnel’s mouth and Tana Nile seals it off with her stasis gun. And
then the Warriors Three tell Thor the bad news: Balder the Brave has
returned—but he has gone mad….
