Available here on picture disc, Danger Days: The True Lives of the Fabulous Killjoys (often referred to as simply Danger Days) is the fourth and final studio album by My Chemical Romance, released on November 22, 2010. Its songs are associated with the band's well known sound of alternative rock, pop punk, and punk rock as well as new elements, including power pop, pop rock, and electronic rock. The inspiration for the album comes from contemporary rock, psychedelic rock, and protopunk bands of the sixties and seventies. In addition, the group has stated that there is a strong influence of cinema on the record.

The album's recording process took over a year, in which the band recorded more than thirty-six songs, most of which were discarded because the band felt they were not a contribution to the genre. The final edition of the album and video clips created a theme for the album, similar to the movie Blade Runner. The album's storyline follows a city in post-apocalyptic California in 2019, where a few outsiders called Killjoys fight against a corporation that controls the people. In 2013, frontman Gerard Way published a comic that continues the story described in the album.
