Answer the question at the end by quoting:

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.
Charles Xavier met Gabrielle Haller while he was working in an Israeli psychiatric facility where she was one of his patients. Xavier was secretly using his psychic powers to ease the pain of Holocaust survivors institutionalized there. The two had an affair that resulted in the birth of their son David. Xavier was initially unaware of this, as Gabrielle never told him she was pregnant. When he was very young, David was among the victims of a terrorist attack, in which he was the only survivor. The trauma of the situation caused David to manifest his mutant powers, incinerating the minds of the terrorists. In the process, he absorbed the mind of the terrorist leader, Jemail Karami, into his own. Being linked to so many others at their time of death, he was rendered catatonic, and remained in the care of Moira MacTaggert at the Muir Island mutant research facility. The trauma caused David's personality to splinter, with each of the personalities controlling a different aspect of his psionic power. Karami struggled for years to separate his consciousness from David's. Using David's telepathic abilities, he reintegrated the multiple personalities into David's core personality. Some of the personalities resisted Karami, and two proved to be formidable opponents: Jack Wayne, a swaggering adventurer, who commands David's telekinetic power, and Cyndi, a temperamental, rebellious girl who controls David's pyrokinetic power. Wayne intended to destroy Karami's consciousness to preserve his own independent existence within David's mind. Neither personality succeeds, and Karami, Wayne, and Cyndi continue as David's dominant personalities. During his time at Muir Island, David emerged from his catatonia. Soon after, David was possessed by the Shadow King, who used his powers to psychically increase the amount of hatred in the world and feed on the malignant energy. During this time, the Shadow King, as David, killed the mutant Destiny. The X-Men and X-Factor fought the Shadow King, and as a result, David was left in a coma.

Some context: Nicholas Edward Cave (born 22 September 1957) is an Australian musician, singer-songwriter, author, screenwriter, composer and occasional film actor, best known as the frontman of the rock band Nick Cave and the Bad Seeds. Cave's music is generally characterised by emotional intensity, a wide variety of influences, and lyrical obsessions with death, religion, love and violence. Born and raised in rural Victoria, Cave studied art before turning to music in the 1970s. As frontman of the Boys Next Door (later renamed the Birthday Party), he became a central figure in Melbourne's burgeoning post-punk scene.
In 1973, Cave met Mick Harvey (guitar), Phill Calvert (drums), John Cochivera (guitar), Brett Purcell (bass), and Chris Coyne (saxophone); fellow students at Caulfield Grammar. They founded a band with Cave as singer. Their repertoire consisted of proto-punk cover versions of songs by Lou Reed, David Bowie, Alice Cooper, Roxy Music and Alex Harvey, among others. Later, the line-up slimmed down to four members including Cave's friend Tracy Pew on bass. In 1977, after leaving school, they adopted the name The Boys Next Door and began playing predominantly original material. Guitarist and songwriter Rowland S. Howard joined the band in 1978. They were a leader of Melbourne's post-punk scene in the late 1970s, playing hundreds of live shows in Australia before changing their name to the Birthday Party in 1980 and moving to London, then West Berlin. Cave's Australian girlfriend and muse Anita Lane accompanied them to London. The band were notorious for their provocative live performances which featured Cave shrieking, bellowing and throwing himself about the stage, backed up by harsh pounding rock music laced with guitar feedback. Cave utilised Old Testament imagery with lyrics about sin, debauchery and damnation. Cave's droll sense of humour and penchant for parody is evident in many of the band's songs, including "Nick the Stripper" and "King Ink". "Release the Bats", one of the band's most famous songs, was intended as an over-the-top "piss-take" on gothic rock, and a "direct attack" on the "stock gothic associations that less informed critics were wont to make". Ironically, it became highly influential on the genre, giving rise to a new generation of bands. After establishing a cult following in Europe and Australia, the Birthday Party disbanded in 1984. Howard and Cave found it difficult to continue working together and both were rather worn down from alcohol and drug use.
Did he have any hobbies in his early years?
A:

IN: Hopkins was born at 512 Tenth Street in Sioux City, Iowa, the fourth child of four sons and one daughter of David Aldona and Anna (nee Pickett) Hopkins. His father, born in Bangor, Maine, ran a harness shop (after an erratic career as a salesman, prospector, storekeeper and bowling-alley operator), but his real passion was bowling, and he eventually returned to it as a business. Anna Hopkins, born in Hamilton, Ontario, had moved at an early age to Vermillion, South Dakota, where she married David. She was deeply religious and active in the affairs of the Methodist church.

In March 1933, Roosevelt summoned Hopkins to Washington as federal relief administrator. Convinced that paid work was psychologically more valuable than cash handouts, Hopkins sought to continue and expand New York State's work-relief programs, the Temporary Emergency Relief Administration. He supervised the Federal Emergency Relief Administration (FERA), the Civil Works Administration (CWA), and the Works Progress Administration (WPA). Over 90% of the people employed by the Hopkins programs were unemployed or on relief. He feuded with Harold Ickes, who ran a rival program--the Public Works Administration--which also created jobs but did not require applicants to be unemployed or on relief. FERA, the largest program from 1933 to 1935, involved giving money to localities to operate work relief projects to employ those on direct relief. CWA was similar but did not require workers to be on relief in order to receive a government sponsored job. In less than four months, the CWA hired four million people, and during its five months of operation, the CWA built and repaired 200 swimming pools, 3,700 playgrounds, 40,000 schools, 250,000 miles (400,000 km) of road, and 12 million feet of sewer pipe. The WPA, which followed the CWA, employed 8.5 million people in its seven-year history, working on 1.4 million projects, including the building or repair of 103 golf courses, 1,000 airports, 2,500 hospitals, 2,500 sports stadiums, 3,900 schools, 8,192 parks, 12,800 playgrounds, 124,031 bridges, 125,110 public buildings, and 651,087 miles (1,047,823 km) of highways and roads. The WPA operated on its own, and on selected projects in cooperation with local and state governments, but always with its own staff and budget. Hopkins started programs for youth (National Youth Administration) and for artists and writers (Federal One Programs). He and Eleanor Roosevelt worked together to publicize and defend New Deal relief programs. He was concerned with rural areas but increasingly focused on cities in the Great Depression. Before Hopkins began to decline from his struggle with stomach cancer in the late 1930s, FDR appeared to be training him as a possible successor. With the advent of World War II in Europe, however, FDR himself ran again in 1940, winning an unprecedented third term.
