(These are all the official ship child O.C.s for this anon)

Ｌ．Ｉ．Ｓ．

(Laboratory Installation System)
(MCU)

an unfinished android discarded by Tony Stark. He just couldn't seem to get this tech to work. There would always be an issue with the mainframe or the code and once he realized he was devoting too much time on this failed project, he tossed her to the trash. Though one day, he did bring Dr. Stephen Strange into his lab for the fun of it to see what he could do, and the sorcerer actually got the bot to sufficiently work. Furious that a magician could actually fix the tech that he couldn't, Tony disposed of L.I.S. once and for all- At least the engineer thought he threw her away for good. Branded with a mix of both Stark technology and magic, L.I.S. quickly went undercover to channel her powers until the day she can get back at her creators.

magicaloffspring

a child born from magic between Loki Friggason and Stephen Strange. Months into their budding relationship, the sorcerers finally spent a night together. Little did either of them know sparks from their magic had an alternate effect. Magic's just like that okay? During the events of Ragnorak, Stephen found a teenager in the sanctum. Their strong resemblance to both Stephen and Loki gave him away and Stephen kept the child as his own. The kid is hardly around the sanctum, and if people ever do see him, the child is passed off as Dr. Strange's new apprentice. Otherwise, Rene does spend a majority of their time in Kamur-Taj, not for the magic, they're indifferent to that, but for the martial arts. Rene is content with not becoming a sorcerer like their fathers, they've learned through rumors that Loki had given magic a bad name, even with his infamous title for being the god of Mischief; and as for Stephen, as professional as the sorcerer may seem, Rene has studied how reckless his magic actually is. So if anything, they believe destiny has something much different in store for them.
