What are your DCU headcanons?

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

Mine is that Mr. Terrific gave himself genetic modifications, but in a cool scientific way, not just here I'm a super soldier. For example, he upped his muscle density so that he could have peak strength without having to work out as much or worry about getting too swole. He also increased his bone density so he's harder to break, and lastly, he gave himself a “healthy” case of Scleroderma, which is a disease that causes people's skin to harden due to over production of collagen. 👍🏾
