Charas and Frisks everywhere dear lord. okay these are the cannon Charas and Frisks on Colorverse, they will appear one time or another, also those are the nicknames between each other.
[[Have some Asriel and Chara spending time together-
My hc for UF!Asriel and Chara is that Asriel’s the one that slowly warms up to Chara and Chara always being that forgiving type to Asriel is always kind and opening to the monster. They develop this weird friendship where Asriel can be pretty cruel and just plain mean to Chara and they’re not fazed by his actions one bit. In fact they always offer some sort of friendship or acceptance towards the prince and Asriel would be mad for a few minutes and tease them but later- you get what the picture up there happens.
Asriel’s also the one that gets angry at Alphys when he finds out she’s the one who poisoned Chara for the determination experiments and before she gets a chance to use Chara in the experiment, Asriel absorbs their soul and takes the body to the surface since Chara would always talk about the field of flowers they loved up there.
And that’s where the humans spot them and attack Asriel and Asriel was going to fight back but Chara held them and Asriel ends up taking the body back to the Underground and all the way to the ruins. Where Asriel uses the last of their energy to bury Chara and die on top of their grave.
For some reason, since Flowey is the monster that helps you through the underground and Flowey in Undertale is basically Asriel without a soul- I just felt that Asriel would have a shred of humanity from Chara which is why he’s so determined to help Frisk as a flower. It was the last thing he would feel as he died on top of Chara’s grave so I thought that the feeling would carry over to his soulless self- or well most of Chara’s traits in a way.
Although Frisk is able to revive the old Asriel from the time before he met Chara when going on a Survival Route (I think that’s what people are calling it now in Underfell) and fight Chara at the end who will force them to reset no matter how many times they go against them.
At the post end for the Redemption Route- Chara and Frisk reset the timeline and exist within the void leaving Asriel to remember everything and reset to Undertale- or at least that’s what I have so far-]
