Psionex are a team of comic book supervillains and occasional anti-heroes in the Marvel Comics universe. Publication history Created by Fabian Nicieza and Mark Bagley, Psionex first appeared in The New Warriors #4. Fictional character biography Psionex are a group of artificially created superhumans who appeared as enemies of the New Warriors. The members are young people (assumed late teens to early twenties) altered by genetic, chemical, or biosurgical means by Harmon Furmintz of the Genetech Corporation to gain superpowers. They first battle the team of similarly aged heroes known as the New Warriors early in the latter team's career, but are soundly defeated and restrained. They later violently attempt to escape Genetech's custody, feeling that they are little more than lab specimens, but are again opposed by the Warriors; this battle would lead to the rebirth of Terrax, a former herald of Galactus whose essence had been contained at Genetech. Mathemanic and Impulse volunteer to aid the Warriors against Terrax (Mathemanic out of altruism, Impulse out of battle lust), but both receive severe injuries in the fight; though Mathemanic recovers and returns to his studies of mathematics, Impulse's injuries require him to permanently use a wheelchair, and he is forced to retire his costumed identity. The rest of Psionex escapes during the battle and go their separate ways. Warriors members Nova and Marvel Boy later check in on Pretty Persuasions at a New York City strip club, and Coronary would return to Genetech voluntarily for help in controlling his powers and possibly returning him to human form. Asylum struck out on her own, resurfacing in Central Park fighting Nova and two other Warriors, Firestar, and Speedball, a fight that ends with the female Asylum's disappearance. Henrique Manuel Gallante, a drug-addicted mutant with powers allowing him to access the Darkforce dimension, takes the name Darkling. Driven mad by his abilities, he attacks New York. Several superheroes are able to convince Gallante to stop, and Gallante disappears into the Darkforce dimension. He later returns to Earth through Asylum's mask. He takes her name and regroups Psionex as "heroes" under his leadership, including Impulse, whose powers allowed his body to eventually heal its injuries. After an extended run of crime-fighting in which much excessive force is used to apprehend criminals, the team becomes wanted by the law after a boy dies in an encounter with Asylum, and Psionex is again opposed by
