concepts for toriel and asgore for that personality switch au i was dabblin in. i decided to keep to the theme of switching just two main, core traits between each character, so we get a spiteful grief-blind toriel, and a wise do-nothing asgore.
toriel is the one who decides to wage a war on humans, while asgore gives up on getting to the surface entirely - but toriel is still self-isolated in the ruins, and asgore is sitting on the throne. having a king that loafs around and doesn’t try to fix anything has a ... negative effect on the underground. toriel takes advantage of people being desperate for someone to do something.
these two are pretty much the root cause for most of the other characters developing how they did.
