"Deadpool Corona" was a former SWAT soldier who was diagnosed with terminal cancer. At the Ferret Bar, "Deadpool Corona" is approached by a recruiter from a secret program offering an experimental cancer treatment that results production in a mutagenic serum designed to activate DNA mutation. Adrenaline is needed to activate the serum, and Deadpool's Crown is subjected to all sorts of monstrous tortures that do not bring success. Subsequently, the hardest test falls on his shoulders - placement in a sealed chamber that lowers the level of oxygen, until the moment of final suffocation.
