Ok wait my thoughts on breeding kinks in DC:
Garth (he wants cute little chubby babies to call guppy, he’s a little nervous bc of his experiences but he loves the idea)
Killer Croc (loves the idea of breeding and everything but would be terrified to have an actual baby that looks like him bc he’d worry for them :c )
John Stewart (I think he’d really like the idea of having a nice little family and the domesticity of it, sex is just a fun perk)
Booster Gold (a mini him sounds so fun and he would LOVE the whole claiming thing and would get super invested and want to try for a baby every 5 hours until it sets)
Superboy Prime “c’mon babe Superman has a kid! Lots of heroes have legacy kids! And I’ve read aaall the comics so I’d totally know what to do when they get powers! Please my sweet milf?” (total horndog)
Bonus: I think Jason and Dick might be into the whole “claiming” and creampies and everything but their relationships with parents and everything are complicated so they might be iffy
