Age Regressor! Conner Kent / Superboy
Conner never had a childhood as he was made by Cadmus and when he got introduced into the world he was used as a weapon and then rejected by Superman (his dad) I think this would've led him to age regressing without even knowing it
He's very gentle and quiet when he's regressed which is almost completely different to how he is when he's big
He regresses quite young most of the time, usually <1-2, sometimes 3
Even regressed he doesn't like onesies / "suits" he'll wriggle around and try and pull it off most times
Sometimes he does like them, usually when he's feeling really tiny
The whole team thinks he's adorable, he loves being called "Supey" by Wally when he's little, it makes him feel small
Usually non-verbal while regressed. But he babbles non coherent noises a lot
M'gann has a private mind link set up with Conner for when he's regressed. It's the easiest form of communication for them
Conner loves milk. He almost always has a bottle of milk with him
When he's regressed his usual black and red shirt is switched out for a Superman (blue, red and yellow) shirt. The team is sworn to secrecy about it
Usually he mostly just wears his Superman shirt and a pull up, since trying to wrestle a super strength toddler into anything they don't want would be nearly impossible
He loves spending time with other regressors on the team, even though he struggles to share his toys sometimes
Sometimes he'll go missing and scare everyone but he's usually just curled up asleep with Wolf
He LOVES Sphere even more when he's regressed, he'll babble to her and get really excited when she makes robot noises back to him
He loves riding in the Bioship
He does have a plush Superman toy which he carries everywhere
He always has a paci clipped to his shirt because he gets incredibly upset if he doesn't have something to suck on (and no one wants a super tantrum)
Superman has taken care of him when he's regressed (first time was involuntary and impure regression) while it was tense at first it ended up being really therapeutic for both of them.
He refers to Superman as his dad when he's little
He has super noise cancelling headphones made by Batman and Zatanna to help him not get overwhelmed when he's regressed
Conner has been found walking around without clothes on because the texture overwhelms him
He loves baths and showers with his Mama (M'gann) they really help calm him down
