What are your DCU headcanons?

[u/Amaranthia0320]

They can be big ones or little ones, I’m just loving this new universe and all the detail.

An inconsequential headcanon I have is that because Lex found weaknesses for Superman and things to avoid for Ultraman simultaneously, he originally included a cape in Ultraman’s costume, but removed it after developing more and more ways Superman can be fought like pulling his cape

I like to think that Jimmy drank a love potion and is not naturally attractive. It's such a silly comic book thing to do.
