- This article is about the band's alter-egos; for the album that the concept comes from, see The Black Parade.
The concept behind the alter-ego is based on Gerard's belief that when you die, you are met by prominent memory from your life. The album follows the story of The Patient as he is met in death by The Black Parade, an abstract memory from his childhood written about in the album's lead song, "Welcome to the Black Parade" ("When I was a young boy/My father took me into the city/To see a marching band ..."). The Patient dies and The Black Parade take him on an odyssey through his life. In shows during The Black Parade World Tour and in the videos for "Welcome to the Black Parade" and "Famous Last Words", the band poses as The Black Parade themselves, showing The Patient his life as he dies.
The band began posing as The Black Parade in the videos for "Welcome to the Black Parade" and "Famous Last Words", and toured posing as The Black Parade as well. In the first show of The Black Parade Tour at Hammersmith Palais in London, the venue announced that as My Chemical Romance couldn't make it to the show, The Black Parade would be playing instead. After some audience disappointment, it became clear that it was just My Chemical Romance posing as The Black Parade. The band stopped using The Black Parade alter-ego on October 7, 2007 at the last show of The Black Parade World Tour. The show, held at Palacio de los Deportes in Mexico City, was later featured on The Black Parade Is Dead! and ¡Venganza!, released in 2008 and 2009 respectively.
