Did You Just Punch Out Cthulhu: Roleplay
- Destroy The Godmodder is a great place for this. Many such creations have died, up to, and including, Cthulhu himself.
- There is, of course, the godmodder, who despite being powerful enough to take on gods, dies at the end anyways.
- Tripocalypse plays with this trope by having unnamed NPCs Punch Out God as part of the prologue (and promptly get out of the spotight), which allows the setting to exist in the first place.
