Background: 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.
Context: 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."

Answer: Xavier's greatest opponent,

Background: Rain was born as Jung Ji-hoon on June 25, 1982, in Seosan, South Chungcheong Province in South Korea. His mother died in December 2000 as she struggled with diabetes. In the same year, Rain was recruited as a trainee for JYP Entertainment, led by recording artist and producer Park Jin-young. In a CNN interview and also in a Discovery Channel documentary called Discovering Hip Korea, he recalled being repeatedly rejected because of his looks: "In fact, I was told after one audition that my singing and dancing was great
Context: On his World 2007 tour, his scheduled concerts in Shanghai, Toronto, San Francisco, and Hawaii were canceled, followed by the last concert in Los Angeles. The last event at the Staples Center was canceled only two hours prior to opening: Rain's producer blamed the situation on financial problems of the local promoter, while the local promoter blamed Wellmade STAR M calling them too "incompetent to handle the situation".  On March 19, 2009, a federal jury in Honolulu found that Rain, his former management agency JYP Entertainment, and two other promotion companies were guilty of breaching a contract and defrauding Honolulu promoter Click Entertainment for $2 million (originally just over $1 million) after the Hawaii concert was canceled and the promoters were not refunded the $500,000 licensing fee. Rain and JYP were ordered to pay $2.4 million each in punitive damages, $1 million for damages related to the fraud, and $2.3 million for breach of contract.  A separate lawsuit filed by promoters Wellmade STAR M was dismissed by a South Korean court on January 28, 2010. Judge Bae Kwang-Kuk ruled in favor of Rain and blamed the plaintiff for poor preparations surrounding the canceled U.S. tour.  In April 2010, Rain and other J. Tune Creative shareholders were accused of embezzling money from the company by a fabric manufacturing company. The company claimed they suffered financial losses. Rain and the shareholders were acquitted of the charges in December of that year. He was re investigated in September 2011 after a discrepancy was found, but was later acquitted again in June 2013.
Question: What was the real problem
Answer: while the local promoter blamed Wellmade STAR M calling them too "incompetent to handle the situation

Background: Cuban was born in Pittsburgh, Pennsylvania. His father, Norton Cuban, was an automobile upholsterer, while Cuban has described his mother, Shirley, as someone with "a different job or different career goal every other week." He grew up in the suburb of Mount Lebanon, in a Jewish working-class family. His paternal grandfather changed the family name from "Chabenisky" to "Cuban" after his family emigrated from Russia through Ellis Island.
Context: On January 4, 2000, Cuban purchased a majority stake in the NBA's Dallas Mavericks for $285 million from H. Ross Perot, Jr.  In the 20 years before Cuban bought the team, the Mavericks won only 40% of their games, and a playoff record of 21-32. In the 10 years following, the team won 69 percent of their regular season games and reached the playoffs in each of those seasons except for one. The Mavericks' playoff record with Cuban is 49 wins and 57 losses, including their first trip to the NBA Finals in 2006, where they lost to the Miami Heat.  On June 12, 2011, the Mavericks defeated the Heat to win the NBA Finals. Historically, NBA team owners publicly play more passive roles and watch basketball games from skyboxes; Cuban sits alongside fans while donning team jerseys. Cuban travels in his private airplane--a Gulfstream V--to attend road games.  In May 2010, H. Ross Perot, Jr., who retained 5% ownership, filed a lawsuit against Cuban, alleging the franchise was insolvent or in imminent danger of insolvency. In June 2010, Cuban responded in a court filing maintaining Perot is wrongly seeking money to offset some $100 million in losses on the Victory Park real estate development. The lawsuit was dismissed in 2011, due in part to Cuban asserting proper management of the team due to its recent victory in the 2011 NBA Finals. In 2014, the 5th Circuit Court affirmed that decision on appeal. Following his initial defeat, Perot attempted to shut out Mavericks fans from use of the parking lots he controlled near the American Airlines Center.  In January 2018, Cuban announced the Mavericks would be accepting Bitcoin as payment for tickets in the following season.
