what is Undertale, Underfell , and Underswap Sariel's relationship with Flowey or Temmie in Swap Sariel's case?
I was going to draw pictures to go long with this but.. I'm too lazy.
Undertale Sariel has a love-hate relationship with her half-brother Flowey/Asriel, they never really got along. Between Sariel trying to pluck his petals when she was a baby and throwing him in the freezer as of now, UT Sariel very much mistreats him and he's not all that nice either... but will try to protect her from harm (but it's not like Sariel needs it anyway)
Underfell Sariel has a close relationship with Flowey/Asriel and cares for him a lot, between him and Frisk, UF Sariel is still closer to Frisk than Flowey but treats him nicely. There relationship isn't seen a lot but they are definitely a lot closer than any other AU Sariel's relationship to him.
Underswap Sariel relationship with Temmie isn't that good, US Sariel as a baby liked to pull Temmie's tail and ears and even sit on them.. basically rough behavior a baby would do to torment a cat. Unlike, UT and UF Sariel, she doesn't know Temmie is her half-sibling or anything so she treats them like a pet than a sibling. There relationship isn't very relevant since Sariel doesn't spend much time with Temmie at all.
Though US Sariel does somewhat know Flowey, aka the Flowe Village, when she was a baby.. Underswap Sans and Toriel brought her there, but forgot to feed her first... so, what you might have already guessed, she ate a Flowey. She's still not allowed back there, none of the other AU Sariels ever done this besides her. ("it tastes like the dust under the rug" - baby US Sariel, probably..)
You can love a character & still admit when they’re wrong. I love Chara but I acknowledge their flaws (none, they're perfect) and I can hold them accountable for their wrongdoings (they've never done anything wrong in their life) an call them out on their actions (which are always right).
Introducing: Ragel The Raver! + Minor Old Home info
A jolly little mushroom that loves to dance! They take residence in the marsh in front of Old Home.
Speaking of which, I'd imagine Old Home would have an aesthetic similar to the Lunar Sea Spire from Steven Universe! It would have floor that Chara would have to ascend, with lower floors being blocked off and saved for the eventual Underswap Yellow (will probably be called Underswap Purple instead)
Asgore's house would be similar to the Sea Shrine, once again from Steven Universe
Here's the replacement for Flowey in my version of underswap, Bonnie the Bonsai!
Truthfully, i was never a big fan of swapping asriel with monster kid and swapping flowey with temmie, so instead I have Asriel swapped with Chara, Monster Kid swapped with Snowy, Temmie swapped with the dog, and Flowey replaced with a bonsai tree, as a reference to the red leaves in the ruins. Also frisk is the only character who doesn't swap with anyone.
Also special thanks to ChrisTheRaccTamer for his tweaks to the sprites, and feel free to ask any questions you may have about the AU!
