to revamp Generation X, as part of the Counter-X rebranding of several second-tier X-titles (the others being X-Force and X-Man). Ellis acted as 'plotmaster', while Brian Wood handled the actual scripting chores and later acted as sole writer of the series. Fan response was positive, largely because Ellis and Wood dealt with the teenaged cast without resorting to cliché. However, in early 2001, Marvel Editor-in-Chief Joe Quesada cancelled Generation X, in addition to five other X-Books, arguing that so many mutant superhero books had become redundant. Also, X-Men writer Grant Morrison wanted to add a new cast of teenage mutants to the Xavier Institute in New York. In Generation X #75, the team disbanded and the Massachusetts Academy closed. After the series Banshee Banshee, distraught and possibly suffering from a breakdown, founds the X-Corps, a group of mutant adventurers who came into conflict with the X-Men over their questionable methodology and membership. Among the group are several former members of the Brotherhood of Mutants. It is revealed that Banshee was having the new Mastermind, the daughter of the deceased original Mastermind, manipulate the Brotherhood's members into having them work with him. However, it turns out that Mystique was posing as one of the members, Surge, and she is working with the new Mastermind behind Banshee's back. Mystique helps the brainwashed members to revolt; two members of the X-Corps are killed and Mystique stabs Banshee through the throat before being stopped by the X-Men. Banshee survives the attack and recuperates in the hospital. In 2006's X-Men: Deadly Genesis, Banshee is killed by Vulcan, Cyclops and Havok's long-lost brother, while attempting to rescue an airplane full of innocents. Later, Banshee's daughter Siryn takes the title of Banshee in his honor. Sean is latter resurrected by the Apocalypse Twins by the Death Seed as a Horseman of Death. Chamber Chamber starred a four-issue mini-series, X-Men Icons: Chamber, written by Brian K. Vaughan. Later, after a reluctant recruitment into the X-Men, Chamber was an active part of the team in battles with long-time X-Men villains Mystique and Vanisher. He subsequently underwent a mission for the X-Men (under the 'guidance' of Wolverine) to infiltrate Weapon X and learn the truth about the team. During his time there, Chamber had his face and most of his body restored by Weapon X, as an incentive to join them. He later disappeared with the rest of Weapon X
