The Sun from my Kidclipse AU, where Eclipse formed in Sun’s head as a small child, designed Bloodmoon and Lunar to be toddlers because he refused to be the baby brother, and proceeded to lash out and mostly follow canon (he bullied Roxy while pretending to be Sun instead of the whole maternity chip thing) while pretending to be an adult until Sun went into his own head to meet him (right after his fight with Moon but before the Witherstorm would’ve happened), and found a traumatized child terrified of being locked up again instead of the big scary villain he was expecting.
Sun and Moon proceeded to step up as coparents for him. And get him therapy. He still has a fear of magic from that suppression spell Grandpa Golden used during their first meeting.
Kidclipse was already in the process of building Toddlunar, so he kept that a secret, causing Mama Sun to freak out when he woke up in Moom (Mom Moon). Glamrock Freddy was the one who got him to admit to Lunar and frantically apologize, and was deemed Papa (thanks to a serious of misunderstandings, Roxy ended up believing Kidclipse is Sun and Glamrock Freddy’s kid, and that Sun was acting weird because he was pregnant. And she ended up spreading that rumor.)
The kids got a body and things were calm until October, when Toddlunar let slip that Bloodmoon exists. Babyblood are still super bloodthirsty, because they were still made to break that firewall, and they still caused July 16 because they were in Mama Sun’s body. Their bloodlust construct body was much smaller and weaker, though, so they’ve been limited to eating mice since they ran off.
Dauncle Monty made them a tiny nanomachine body, and usually babysits them during Daycare hours because nobody trusts them near the human kids.
Dadcode woke up, adopted the kids immediately, and has since gotten his own body that looks exactly like the mindscape one. He’s the one who takes the twins hunting, and tries to guide their eating habits towards bad people.
