Here is my Deltafell Kris sprite! If you want to use it, make sure you ask for my permission and you give me credit!
Since Kris doesn't usually speak, I will just explain their story. Kris is Toriel and Asgore's adaptive human child and Asriel's adaptive younger sibling (I like to think brother). Despite being very close with their parents, they had a terrible relationship with Asriel. Asriel would often make fun of Kris for being the only human in the area and tell an awful lot of lies about them, and that is why Kris barely has any friends. Asriel purely hates Kris, and it could get physical sometime. One time, Asriel slashed Kris in the face with one of his claws in a fit of rage, causing a massive scar to form on Kris' cheek. After Asriel left for university, Kris felt relieved, but Asriel's damage still left a mark on Kris' life. A bunch of people in school believed Asriel's rumors about them, so Kris would often be bullied by other students in the school, especially by Noelle and Berdly. The only person who Kris is really friends with in their school are their teachers, Toriel (who also raised them) and Alphys, and Susie, who never believed in any of Asriel's rumors. They also get along with most of the people in town, that do not believe in Asriel's rumors. Kris likes to wear ripped clothing, despite the fact that Toriel thinks it looks ridiculous. They also trusted Ralsei, despite the fact that Susie thought there was something suspicious about him. This change when Ralsei turned out to be a even bigger threat than the King.
