**Yuji and Mahito (*****Jujutsu Kaisen*****)** \- Yuji hates Mahito because he killed Jumpei. Mahito fucks with Yuji becauses he sees him as his "natural enemy". It goes so far that (Modulo spoilers) >!Mahito spends 80 years in the afterlife waiting for Yuji to die, and when Yuji finally arrives (though he's actually still alive; it's complicated) Mahito immediately tries to kill him.!<

**The Playtime Employee and Huggy Wuggy (*****Poppy Playtime*****)** \- Huggy spent like several hours going down to the deepest depths of the factory just to catch up to the Employee and immediately guns for the kill whenever he spots them. Bonus points for the fact that the Prototype wants to kill Huggy for failing him, so he's not even following orders anymore this is personal.

**Susie and the Roaring Knight (*****Deltarune*****)** \- Ever since their first encounter in Chapter 3, Susie has hated the Knight more than any of her previous opponents including King, and she tries to attack it anytime they encounter eachother in Chapter 4. The Knight, for what it's worth, loves ragebaiting and aurafarming on Susie.

**Alastor and Vox (*****Hazbin Hotel*****)** \- To put things into perspective: Vox hates Alastor *so much* that he straight up left his boyfriend mid-sex just to run the ones with him. Alastor doesn't hate Vox nearly as much, but he still loves ragebaiting him and won't miss a chance to fight him.

Literally on-sight beef
