I've been considering doing a future JLI drawing with Rip and the kids of the JLI. And if Rip can't carry on the "Gold" name I suppose Rani or Daniel and Roses' future kid could. I want to do a Tora/Guy kid but I can't decide if it should be a boy or a girl. I'm kind of leaning towards a boy if Milagro is the GL but I'm having a hard time thinking of a boy of Guys' having ice powers. I guess I just naturally see Guy having a girl and spoiling her rotten. Of course I thought the same thing about Booster which changed with Rip then sort of worked out with Rani appearing.
I don't really see Bea as the mother type, more of the doting aunt. Gavril seems like he'd have no objections to being a father but you never know. Cap has grown up kids (no idea if they currently have kids) but none of them are in the superhero business. Powergirl? Well she did have a kid once that grew up fast and no one wants to him mention again. Pretty sure she never actually gave the kid a name outside "baby" anyway. I do wish that Ralph and Sues' baby lived somehow but they haven't mentioned the kid since it was revealed that she was pregnant when she died. Dmitri had a boy and girl although they might be slightly older than the rest. Scott and Barda exist again but I'm not sure how that works. Their child would be awesome though.
Am I forgetting anyone with kids or couples that could have kids in the JLI?
