Nice (awesomely nerdly thread):

the logic being you would gain superhuman powers and hence cool names like dying-of-cancer-man and oh-the-burning-pain-man.

That would be sweet! As Dying-of-Cancer Man, you could fight crime using the awesome power of your inspiring tale of courage!

DoCM: “Stop, villain! *pant* Your nefarious schemes are over! *hack cough* Oh, there goes the last of my hair…”

Villain: “Your body wracked with cancer and the effects of chemotherapy, I’m surprised you can stand, much less threaten me.”

DoCM: “I just want to leave the world… a better place than I found it…”

Henchman: “You can’t hurt him, boss… He’s dying of cancer!”

Villain: “You’re right! Such courage and love of life… We surrender, Dying-of-Cancer Man!”
