The Black Clouds

The Black Clouds were an underground organisation of pirates and assassins led by a demon of the underworld known as Malthus. After Murdoc broke out of jail in Mexico with his associate Pablo, the pair began a career in arms dealing. Using the Hell Hole at kong to send weapons to and from the underworld. Eventually, Murdoc scammed the organisation by selling them fake/broken weaponry he'd purchased from a country in the process of upgrading, then after repainting them he sold them on as 'brand new' stock. Malthus sent for his goons to terminate Noodle during the El manana music video as a warning to Murdoc not to cross him, but after Noodle's unexpected survival via parachute, the Boogieman was sent to kidnap her from Kong Studios while in the process of packing to leave the band. Murdoc drunkenly stumbled into Hell in an attempt to save Noodle but couldn't recall the events of his travels, it was presumed to be unsuccessful until Noodle's reappearance in the 'Madam' Ident used during On Melancholy Hill's music video. During the siege of Plastic Beach during the April of 2011, it can be presumed that the remaining forces of The Black Clouds, along side their leader Malthus, all perished during the sinking of Plastic Beach.

Trivia

 * The Black Clouds were at some points referred to as the Pirate Jets, they're possibly an entirely different organisation which are commonly referred to as the same for simplicity's sake, but the details are unclear.
 * Malthus and Maazu share a similar description and background in the criminal underworld, it's possible that with 'The Book Ofs' being planned to be apart of the scrapped final music video for Plastic Beach (To Binge,) that Noodle was originally intended to assassinate the leader of the Black Clouds, Malthus, in Tokyo rather than the new villain Maazu, but ultimately scrapped for one reason or another, most likely due to Hewll's tendency to forget the specifics in his storytelling and the absence of previous writer Cass Browne.
