James Gunn didn't want "a Superman who could punch planets":
"I wanted Superman to be vulnerable. I see the online things “Who would beat whom?” — Homelander or Superman or fucking whatever, Adam Warlock or Brightburn, and I’m like, “This is the fucking stupidest fucking conversation.” Like, so then whoever would win this fight means that they’re the best? Because I’ll just go out and write God Man, who can destroy you with a wink. And I win. I win all the fights forever."
