Asriel, a returning character from Undertale, is Kris's older brother and Bernardo's younger brother in Deltarune. Unlike his sibling, Asriel is more open and friendly to the other townspeople. He is very popular in Hometown, and many of Kris's neighbours exclusively talk about him to praise him, unlike Kris. He also has many trophies on his shelf. He likes music, including religious ska. Despite the differences between him and Kris, he does care a lot about them.
