Won't be a fic but it's fun to draw

Code Lyoko characters Backstory swap AU, but their personalities remained the same!

Yumi had Ulrich's backstory

Ulrich had Odd's backstory

Odd had Yumi's backstory

Jeremie and Aelita swapped backstory with some changes

William and Sissi swapped backstory and in their case, position

Yumi was still bitter, but she decided to try be a big sister instead of rue over the fact her parents are not proud of her

Ulrich's many siblings are always on top of him, making him feel unseen and broody because of it (he didn't know his sibs love him though)

Odd's way of coping with his parents' unstable relationship is be a goofy guy

Jeremie had his mother kidnapped, though not for canon lita shenanigans (maybe)

Aelita had both of her parents with her, but still has the canon bs

William and Yumi were childhood friend, but he is less annoying than Sissi, he is more gentle with Yumi compared to Sissi

A headcanon involving devirtualization
