Stan sends Daniel to meet four people who can control their perception of pain, and push their bodies to unthinkable levels. Having created so many fictional pain-proof characters in his comics, Stan never thought real people could possess immunity to pain, but these four individuals perform staggering feats of pain tolerance that challenge the known limits of the human body. Eduardo Lasaga claims he can withstand extreme amounts of bone-crunching weights on his body. But, is he really un-crushable? Evgeny Kuznetsov takes the gore factor to the extreme, withstanding the excruciating pain of dozens of darts penetrating his flesh, but he also doesn't shed a drop of blood. Matthew Ahmet claims he's trained his body to tolerate the same level of pain as the ultimate shaolin warriors. Li Xin's demonstration of skull strength is almost too gruesome to watch, and he claims he's developed a superhuman head, that is virtually indestructible.
