Harry arrived in New York during a Lizardman attack and joined Coulson in fighting the transformed humans. After learning Dr. Lizard planned to contaminate the Catskill Aqueduct, Harry, Tony, Peter, and S.H.I.E.L.D. agents gathered there, where they prepared to face a horde of nearly a hundred Lizardmen.

Dr. Lizard's army of Green-skinned Soldiers attacked S.H.I.E.L.D., but Hawkeye, Crossbones, Coulson, and a Stone Giant overwhelmed them with unexpected powers. As Dr. Lizard realized The Leader's intelligence was outdated, he activated a second plan and summoned more Lizardmen from the sewers.

After discovering that his magic came from Primordial Chaos Force and could observe other worlds, Harry began using it to explore their abilities and gave Gwen the power of flight.

Harry severed the Destroyer Armor’s leg with Chaos Magic and stored it before Loki could retrieve it, but his power then spiraled out of control. After failing to find a safe dimension for the ensuing rampage, he sealed himself inside a collapsing Mirror Dimension, where the Supreme Mage arrived with the Time Stone activated.

• Harry demanded the Destroyer Armor from Loki, then used Chaos Magic and the Sword of Lightning to sever one of its legs and store it in his Pocket Dimension.

• Harry told Thor he had defeated the Destroyer Armor, repaired the damaged town, and demanded compensation for the magical potions destroyed when Mjolnir flew out of his villa.
• Thor said he needed to return to Asgard because Loki had caused trouble, and Harry decided to go with him to discuss matters with Loki.
• Thor failed to summon Heimdall, so Harry opened a Portal to the Bifrost and refused Coulson's request to come along.
• Harry and Thor entered the Portal, and Harry saw that the situation at the end of the Bifrost was worse than he had expected.
