PJO agere headcanons bc im getting into the series again
Percy - Flip. Babysits all the smaller kids and is the favorite despite letting them get away with the most, but also sometimes regresses, in which case he’s a big troublemaker with Leo
Annabeth - Flip, mostly cg. CG for Percy especially, but also helps with the others and helps organize playdates. Regresses to a bit of an older age, mostly around 7ish, the age when she met Luke and Thalia
Grover - CG but not committal, pretty much just a normal dude not too concerned with the roles. He does like to play games with a regressed Percy tho
Tyson - Regressor. Ella is very kind and doting and accommodating for him. He misses Percy when he is regressed but sometimes Percy comes over and he’s not sad about it anymore.
Nico - Regressor. Big time. An entire section of hades cabin is just his regression space, of course filled with everything that is both black and baby-ish that he could find. Tends to fly a bit more solo rather than regressing with groups, but he’s not totally against it, tho he is a bit antisocial when he does and tends to just stick by his cg, Will.
Thalia - she’s not around much but the few times she’s seen Percy regress have been fun for her. Kinda like Grover, not really a cg, but doesn’t mind hanging out with the kiddos
Jason - Older regressor, broadly to around the same age Annabeth does. Will cg occasionally but can’t help usually being the “big” brother to his friends after a while
Leo - regressor, not super tiny baby age but not as old as Jason or Annabeth, but older than Nico. Loves to play with toys all the time omg he will not shut up about his toys he has to bring them everywhere
Piper - a bit like Annabeth, tho I imagine she starts regressing more after Jason passes (if you wanna think about that). She is Jason’s primary CG but usually only cgs during big group stuff as that is when Jason mostly regresses.
Frank - big ol baby. Just the tiniest guy
Hazel - cg for Frank and Percy when he’s around. Very chill, get involved in games and stuff but isn’t as lax as say Percy as a cg
Reyna - secondary cg for Nico, also helps with Jason and Percy
Will - Nico’s cg. Good about enforcing bedtime and making sure the growing boy gets everything he needs.
I’ll edit to add more if I can think of more. I haven’t read the books in a sec so some of the characterization might be weird but eh this is fandom who cares
