Sundowner was a cyborg mercenary who served as the de facto leader of the PMSC Desperado Enforcement LLC. during their activities in 2018, as well as a member of the Winds of Destruction, alongside Mistral and Monsoon. His name was derived from the wind condition that occurs in Southern California. Donning a specialized custom cyborg body, the immense Sundowner wielded two high-frequency machetes known as "Bloodlust." In addition, the two machetes could also be merged into a scissors-like contraption to cause further damage to the enemy. His cyborg serial number was 978-AZQEE.
