Jeez. I based some of the things off of Deadpool himself...but I had to tone that crap down tremendously. Deadpool can survive his head getting blown off, it would just regenerate. Deadpool cannot die....so I changed that xD
Because of his Cancer, the expirement on him...enhanced his cells. So because of this he can now regenerate at a higher rate than even Wolverine. Even survive things that should kill. Beheadment, heart explosion, molecular destruction, etc.
It's...hard to understand Deadpool since he is 'immortal'...yet he killed his Parallel Counterpart....Dreadpool
