Sibling AU
I have this UT/Deltarune AU stuck in my head but it’s too hard for me to draw for some reason because I have no ideas for how to draw them but I NEED to yap about them badly
Kris, Frisk, and Chara are all siblings- that’s been done a million times before, however there are two Asriels. The college aged one is the Deltarune version, and he keeps the name Asriel. Then there’s the younger one that’s around Chara’s age, and his name is Rielas (he couldn’t be named Togore, because that was Kris’s deadname.)
And then there’s also Tenna. Dark worlds aren’t a thing in this AU, so darkners are just regular monsters/humans. Tenna is also adopted into the family and is the oldest sibling.
Timeline:
Tenna is created
Asriel was born five years later
Three years later, Kris was born and adopted within a few months
Five months later, Tenna was adopted.
Three more years later, Rielas was born and was supposed to be their last child. Chara is born around the same time
Six years later, Rielas finds Chara, and they end up adopted
Five years later, Toriel find Frisk and they are adopted. Around this time Toriel and Asgore start fighting more obviously.
Ages:
Tenna: 23
Asriel: 18
Kris: 15
Rielas: 11
Chara: 11
Frisk: 7
I did consider making Ralsei a part of the family, but ultimately decided against it and made him one of Kris’s friends
I’m still on the fence though about if the Vessel should also join the adopted party though. They still exist they’re just more like a ghost, invisible to everyone except Frisk
