[4] He himself is transformed into a muscular, grotesque, goblin-looking monster, granting him superhuman strength, reflexes, stamina, speed and durability, and enabling him to leap great distances.

In an attempt to destroy all evidence of his existence, the Green Goblin kills Norman's wife but Harry manages to escape while the house is burning down.

[7] Under the Goblin's spell, he reveals himself to Parker, telling the boy to give up the Spider-Man identity and work for him, or suffer the deaths of loved ones.

When Parker refuses, the Goblin kidnaps Mary Jane Watson who he attempts to kill by hurling from the top of a bridge.

The battle continues at Osborn's Manhattan penthouse, where the Goblin transforms even further after taking several more OZ injections and begins to choke the life out of Spider-Man.

Harry discovers the scene, picking up a shattered window pane to jam into his father's back, reverting him to his human self.

It also seems that he is no longer under the influence of the hallucinogenic "plasmids" with Norman stating that he has been undergoing a "transitioning stage" during his last confrontation with Peter.

Osborn considers Spider-Man to be his "true" son and belongs with him, so he prevents harm to Peter, but he does humiliate the boy.

[11] When contacted by Carol Danvers, Norman states that he will answer only to Fury; he then transforms into his Green Goblin form and breaks away from security measures, the OZ in his system having re-worked his body in a further process of what he refers to as 'evolution'.

Though no longer haunted by 'plasmids', the Goblin has given in to severe paranoia, believing everyone save him to be insane, and Fury a tyrant that imprisons anyone with the power to stand up.

[13] In his breakout, he enlists the promised help of Electro as payback for freeing him; other supervillains that escape include Omega Red, Kraven the Hunter, and Gwen Stacy (Carnage).

The Goblin's strategy upon escape is simple; Norman appears on a talk show, claiming that Fury held him in a prison against his will, just as he was on the brink of creating a drug to solve America's military problems.

[15] Months before his transformation and apparent death, Norman had Dr. Conrad Markus somehow create another OZ-injected spider which later bites Miles Morales,[16] indirectly due to Aaron Davis being hired by Donald Roxxon.

[20] When Empire State University's engineering facility comes under attack, Morales as Spider-Man encounters the Green Goblin.

[21] After he managed to obtain a sample of the drug that Ultimatum was producing, Spider-Man II was attacked again by the Green Goblin.

[23] It turns out that Ultimatum has been helping the Green Goblin in making an army of Goblinoids as part of his plot to take over Brooklyn.

When the pulse activates, some Goblinoids attacked Captain America at the time when he was giving Miles's friends a ride.

[25] Ultimatum, his henchmen, and the Goblinoids attack Spider-Man II, Captain America, Jefferson, the Prowler, Bombshell, and Starling.
