Resurrection of the Catastrophic Hero

There once was a hero who was deemed the strongest on Earth.
“But he died. How would someone that we killed return?”
“Yeah. I’d love to see him try and come back.”
However, 20 years later, he actually returned!
“Why are you guys so shocked? Did you do something that you feel guilty about?”
‘These motherfuckers. I’m not going to let them be.’
