Fictional character biography
Equinox is an African-American youth who gained superhuman powers due to accidental exposure to his father's malfunctioning equipment after a lab accident; his mother is Margay Sorenson, head of natural sciences at Bard College, while his father was killed in the same lab accident that gave Equinox his powers because he made a mistake. [2]
Equinox's powers were similar to the combined abilities of superheroes the Human Torch and Iceman, with whom he first battled, [3] as well as enhanced strength and durability. His mother attempted to teach herself about her late husband's work to find a way to cure her son, but was ultimately forced to let Equinox commit robberies so she had the resources to carry out her research. The shifting exothermic state of his transformations had a dangerous effect on Equinox's mental state, and he ultimately went on a rampage, engaging in conflict with the superheroes Spider-Man, Yellowjacket, and the Wasp, during which his origin was revealed. The three heroes managed to apparently cure him using technology conceived by his mother and constructed in the Baxter Building while the Fantastic Four were away, Spider-Man refining the technology while Wasp and Yellowjacket kept Equinox busy. [4]
Years later, he fights the Falcon. [5] Afterwards, Equinox joined Vil-Anon, a twelve-step program dedicated to helping individuals overcome their criminal tendencies. [6]
Equinox appears during the Civil War event, and when the registration law is announced, he wants to leave the country again. He contacts Vienna to make him a new fake identity, but unbeknownst to him, Vienna secretly works for Heroes for Hire who apprehend Equinox and several other supervillains. [7]
Equinox is next seen as a member of the Montana team of the Fifty State Initiative, Freedom Force, alongside Challenger, Cloud 9, Think Tank, and Spinner. [8]
During the Secret Invasion storyline, Equinox was revealed to be a Skrull infiltrator and attacked his teammates. The Skrull-Equinox not only had the abilities of Firestar and Iceman to match the real Equinox' powers, he also had some of Spider-Man's abilities. He froze Hardball, Ryder and Riot (of the Skrull Kill Krew) in ice and broke the glass over Think Tank's brain. The Skrull-Equinox was sniped in the head by Cloud 9 using adamantium bullets. [9]
After the invasion is over, the real Equinox is seen, although miscolored, in a support group meeting with the others that had been replaced by Skrulls. [10] Equinox has since retaken active service with the Freedom Force. Due to his criminal past, Norman Osborn chooses his team between the ones assembled by Stark to help some other Initiative teams to apprehend the seceding Heavy Hitters team. [11]
At the start of the Ends of the Earth storyline, Equinox is on a rampage. To defeat him, Spider-Man uses his own version of Green Goblin's glider and bombs. [12]
Following the Avengers vs. X-Men storyline, Equinox participates in a prison riot. Mimic and Rogue respond to the riot. Copying the powers of Equinox, Armadillo, and Man-Bull, Mimic and Rogue stop the riot. [13]
Equinox returns in the All-New, All-Different Marvel when he is brainwashed by Kang the Conqueror's splintered half Mister Gryphon to attack the Avengers. Mister Gryphon creates multiple temporal replicas of Equinox by having his future selves aid him in his assault. [14] However, he is defeated when Spider-Man pretends to be under Kang's influence so that he can identify the earliest version of Equinox present. Once he has confirmed which Equinox was the only one surprised at his conversion, Spider-Man knocks out that version of Equinox, eliminating all the future Equinoxes as well. [15]
