Joanna was an unexpected baby girl who did not get her father´s acceptance because of her poor health status and weakness. She was the second baby in her family, his fahter was militian and her mother was a religious coward woman. Her older brother brother joined the army an eventually he was reported killed. After her brother´s death her father beat her up and finally due to his abusive treatment Joanna developed her mutant powers and accidentally killed him in self defense.
Joanna Cargill grew up bitter and angry at the world for oppressing her as a black woman and a mutant. She found solace in expressing her anger through criminal activity, working as a mercenary-for-hire. She often clashed with other mercenaries, such as Gambit, who she formed a brief romantic relationship with. She had often felt aimless, which led her to use her invulnerability in reckless ways, and made her susceptible to other mutants, such as Apocalypse and Magneto.
Frenzy was created by writer Bob Layton and artist Keith Pollard. Frenzy's first published appearance was in X-Factor #4 (May 1986). Her real name, Joanna Cargill, was revealed in Uncanny X-Men #298, her first appearance as one of Magneto's Acolytes.
Frenzy, like many of the X-Men, started off as a villain. Her first appearance had her battle the original X-Men under their new name, X-Factor. It was later revealed she was field leader of a group of villains, the Alliance of Evil. After a handful of failed attempts to defeat X-Factor, Frenzy found sanctuary among Magneto's Acolytes. Frenzy spent years with this group of fanatics, until Jean Grey mind-controlled Frenzy to fight against her leader, Magneto. After serving with the X-Men for a short while, Frenzy left and was not seen until after M-Day, where she was one of the few mutants to retain her powers. She joined Exodus and his new Acolytes, which were eventually merged into Mister Sinister's Marauders. Frenzy later had part of her brain damaged in a battle with Magneto, though Professor X eventually healed her. Recently, during the Age of X, Frenzy was a member of the X-Men and romantically involved with Cyclops (known as Basilisk). After the timeline was restored, Frenzy retained her memories and continued on with the X-Men, despite her villainous past.
Major Story Arcs
Alliance of Evil
Frenzy started off as a member of the Alliance of Evil, under the command of Apocalypse. Along with her teammates Tower, Stinger, and Timeshadow, Frenzy fought X-Factor several times: first, while trying to recruit Rusty Collins into her group; second, after growing attached to Michael Nowlan's mutant-enhancing powers; and third, while in opposition to the Mutant Registration Act. All three times, Frenzy and the Alliance of Evil were defeated by the group, and were later abandoned by Apocalypse. She left the Alliance of Evil and, for a short time, joined the Femizons and battled Captain America.
Some time later, Frenzy was given an invitation to join the S. S. Superia, a cruise ship owned by the villainess Superia. There, Frenzy served alongside the Femizons, a group of super-powered female criminals, and battled Captain America and Paladin. She also broke free from the Vault, a prison for super villains, and created a ruckus with The Avengers.
Frenzy later found acceptance with Magneto and joined his Acolytes, dropping her codename and simply going by her last name, Cargill. During her first mission as an Acolyte, she attacked a school. During the raid, Frenzy killed a teacher there, who was also a long time associate of the X-men, Sharon Friedlander. Sharon however managed to alert the X-men before she was killed. Frenzy and her teammates Unuscione and the Kleinstock Brothers then sought out a mutant child at the school. When the Acolytes found the mutant child, they soon discovered the child suffered from Down's Syndrome, and attempted to kill him. The X-Men intervened, saving the boy and running the Acolytes off. On other occasions, Cargill attempted to murder Senator Robert Kelly, and also battled Iceman. When Magneto returned, he had the Acolytes join him on Avalon.
When Avalon was destroyed due to a battle between fellow Acolyte Exodus and the demonic Holocaust, Cargill banded together with Cyclops, the Kleinstock Brothers, Unuscione, and Scanner. They were all able to survive the fall to Earth, and later found the X-Men's abandoned Australian Outback base. The surviving Acolytes were then placed in custody, though they quickly escaped and found the remains of Avalon, waiting for Magneto's return. When Exodus took over leadership, Cargill and the Acolytes attacked Wundagore Mountain, though they were eventually defeated by the Avengers.
Upon his return, Magneto chose Cargill to become the ambassador of Genosha. During the Avengers' attack on the island, Frenzy encountered and defeated She-Hulk, and later confronted Quicksilver over his disloyalty to his father, though she was eventually defeated by Scarlet Witch. Later, Cargill ordered all countries of the world to pledge loyalty to Magneto. She was captured by the government, ordering her to inform them of Magneto's plans, but she refused to speak.
Jean Grey broke Cargill out of her confinements and proceeded to mind-control her into joining her rookie group of X-Men. Along with Northstar, Cargill piloted the Blackbird into Genosha, her knowledge of Magneto's base being of great benefit to Jean Grey. During the battle with Magneto, Cargill was used against her will to pummel Magneto, who commented that Cargill was his most trusted Acolyte and that he knew it was mind-control. He then wrapped a steel pillar around her, rendering her useless in the battle. After Magneto's defeat, Cargill somehow regained her senses.
After the events of Decimation, Cargill resurfaced as a member of the new Acolytes, returning to her codename Frenzy along with her costume. She, along with Tempo, battled and defeated Rogue, though Tempo was quickly defeated by Mystique. Northstar and Aurora aided Mystique in knocking Frenzy out of the helicarrier. She then joined Mr. Sinister in order to restore the mutant population. Alongside the Acolytes, Frenzy invaded the X-Mansion in order to find the Destiny Diaries. They ambushed the children of the school, and in the ensuing battle, Frenzy beat Hellion but her skin was inevitably cut by X-23.
The Acolytes, having not found the actual diaries, left the mansion and later battled the X-Men once again during Messiah CompleX, this time alongside the Marauders. Frenzy and the Acolytes escaped Muir Island after the battle with the X-Men by using Tempo's abilities, and kidnapped Professor X, taking his body to an unknown part of the world. Frenzy opposed the idea of keeping Professor X alive, as he never supported Magneto. While Exodus made it clear he wanted Professor X alive, Frenzy confronted the professor, Omega Sentinel, and Magneto, who had been depowered after Decimation, and attempted to kill Xavier. After tossing Magneto aside and severely injuring Omega Sentinel, Frenzy was blinded by Magneto with a surgical laser, which burned part of her brain. Although Magneto revealed she most likely survived, Exodus witnessed the actions and swore to kill him for harming a mutant.
After Professor X infiltrated the Acolytes' headquarters, he found the comatose Frenzy. He used his mutant abilities to piece Frenzy's mind back together, but when she regained consciousness, she immediately attempted to attack him. He threatened to put her back into the coma, calming her down. Exodus later disbanded the Acolytes, which angered Frenzy. She and Unuscione, though opposing the idea of disbanding simply because the "numbers were against them," joined Voght, Tempo, and Random as they traveled to San Francisco. During her time on Utopia, Frenzy befriended fellow super-villain Nekra. The pair participated in a number of riots, and battled Moonstone under the guise of Ms. Marvel. She later was seen rallied with Cyclops against the Nimrods who attacked Utopia.
Age of X
Frenzy is one of the many mutants present in the Age of X timeline. One of the last surviving mutants left, she joins a ragtag group of survivors and begins a romantic relationship with Basilisk (aka Scott Summers). She participates in many of the battles faced by the mutants, and was mentioned as being one of the original members of the Mutant Liberation Front, along with Tempo. Frenzy eventually married Basilisk. After the timeline was restored to normal, Frenzy retained her memories of being with Cyclops, and decided not to have Emma Frost remove the thoughts from her mind. Cyclops, sympathetic to Frenzy, invited her to remain with the X-Men. Later, an enraged Frenzy started to attack Toad after a comment he made, but she was interrupted by Gambit, who calmed her down. She then cut her hair to resemble her Age of X appearance, and swore to Gambit that she was going to become an X-Man.
Frenzy was sent to recover the remaining weapons that were left in Africa after Cyclops (herald of the phoenix force) finished a civil war in the continent. During this time Frenzy stopped an abusive man who was beating his wife because of the ressemblance of her own traumatic past. Joanna managed to stop a small army and let a village recover peace after the conflict.
Powers and abilities
Frenzy is a mutant whose abilities grant her invulnerability, as she has steel-hard skin which is impenetrable by anything other than adamantium. She is resistant to any forms of temperature change, being able to withstand being frozen or engulfed in flames. A by-product of her mutant powers is superhuman strength, powerful enough to battle the likes of She-Hulk or Rogue (with Ms. Marvel's abilities). Although being almost 7 feet tall recently she has seemingly lost height, whether this is due to her mutant powers is yet to be seen.
