Some context: Legion (David Charles Haller) is a fictional superhero appearing in American comic books published by Marvel Comics. He is the mutant son of Professor Charles Xavier and Gabrielle Haller. Legion takes the role of an antihero who has a severe mental illness including a form of dissociative identity disorder, in which each of his alternate personas controls one of his many superpowers. The television series Legion premiered on FX network in 2017.
When Mystique tracked down David years later to get revenge for "his" murder of Destiny, he awakened with his fractured mind healed. David had a new goal, to help his father realize his dream of human-mutant coexistence by killing Magneto, Xavier's greatest opponent, before he had a chance to amass power. He traveled twenty years into the past, when Xavier and Magneto were orderlies at the mental hospital. In the process, he loses his memory. Magneto then accidentally triggers his memory, causing David to go on a rampage, attacking Magneto and revealing the existence of mutants to the public decades too early. Several X-Men who were pulled back in time with him were unable to prevent him from attacking Magneto. Xavier, however, leaped into the path of the psi-knife (the focused totality of Legion's psionic powers) and was killed in Magneto's place, causing the formation of the Age of Apocalypse timeline.  Due to being trapped in the past by David's actions, Bishop enlisted the aid of the new reality's X-Men to travel back in time to confront Legion again. Bishop seized Legion's psi-blade and drove it into his own chest, allowing Legion to see the future that he caused. In his last moments, David apologized for what he did. David's mother, Gabrielle Haller, described having a "maternal loss" afterward, implying she miscarried before giving birth to David.  While David was considered deceased, some of his alternate personalities remained trapped between life and death, manifesting as spirits. When the spirits started terrorizing Israel, Excalibur was called to stop them. After learning that the spirits were refusing death, Meggan used her empathy to calm their rage, convincing them to go "towards the light."

Some context: Glenn Lee Beck (born February 10, 1964) is an American talk show host, political commentator, and producer. He is the CEO, founder, and owner of Mercury Radio Arts, the parent company of his television and radio network TheBlaze. A conservative, he hosts the Glenn Beck Radio Program, a popular talk-radio show nationally syndicated on Premiere Radio Networks. Beck also hosts the Glenn Beck television program, which ran from January 2006 to October 2008 on HLN, from January 2009 to June 2011 on the Fox News Channel and currently airs on TheBlaze.
In 1983 he moved to Corpus Christi, Texas, to work at radio station KZFM. In mid-1985, Beck was hired away from KZFM to be the lead DJ for the morning-drive radio broadcast by WRKA in Louisville, Kentucky. His four-hour weekday show was called Captain Beck and the A-Team. Beck had a reputation as a "young up-and-comer". The show was not political and included the usual off-color antics of the genre: juvenile jokes, pranks, and impersonations. The show slipped to third in the market and Beck left abruptly in 1987 amid a dispute with WRKA management.  Months later, Beck was hired by Phoenix Top-40 station KOY-FM, then known as Y-95. Beck was partnered with Arizona native Tim Hattrick to co-host a local "morning zoo" program. During his time at Y-95, Beck cultivated a rivalry with local pop radio station KZZP and that station's morning host Bruce Kelly. Through practical jokes and publicity stunts, Beck drew criticism from the staff at Y-95 when the rivalry culminated in Beck telephoning Kelly's wife on-the-air, mocking her recent miscarriage. In 1989, Beck resigned from Y-95 to accept a job in Houston at KRBE, known as Power 104. Beck was subsequently fired in 1990 due to poor ratings.  Beck then moved on to Baltimore, Maryland, and the city's leading Top-40 station, WBSB, known as B104. There, he partnered with Pat Gray, a morning DJ. During his tenure at B104, Beck was arrested and jailed for speeding in his DeLorean. According to a former associate, Beck was "completely out of it" when a station manager went to bail him out. When Gray, then Beck were fired, the two men spent six months in Baltimore, planning their next move. In early 1992, Beck and Gray both moved to WKCI-FM (KC101), a Top-40 radio station in New Haven, Connecticut. In 1995, WKCI apologized after Beck and Gray mocked a Chinese-American caller on air who felt offended by a comedy segment by playing a gong sound effect and having executive producer Alf Gagineau mock a Chinese accent. That incident led to protests by activist groups. When Gray left the show to move to Salt Lake City, Beck continued with co-host Vinnie Penn. At the end of 1998, Beck was informed that his contract would not be renewed at the end of 1999.  The Glenn Beck Program first aired in 2000 on WFLA (AM) in Tampa, and took their afternoon time slot from eighteenth to first place within a year. In January 2002, Premiere Radio Networks launched the show nationwide on 47 stations. The show then moved to Philadelphia, Pennsylvania, broadcasting from new flagship station WPHT. On November 5, 2007, The New York Times reported that Premiere Radio Networks was extending Beck's contract. By May 2008, it had reached over 280 terrestrial stations as well as XM Satellite. It was ranked 4th in the nation with over six and a half million listeners. As of July 2013, Beck was tied for number four in the ratings behind Rush Limbaugh, Sean Hannity, and Dave Ramsey.
