This is blue from my universe, he got killed trying to save swap!chara who also died by getting grinded into a meat grinder, and turned into a bunny, and Blue has exact same thing, except instead of being grinded into a meat grinder, he then gets to be fused with his dust and a blood sample of a rabbit only a little, so swap!charas rabbit blood sample is exactly the same as the blood used on blue, so which makes both of them related, and also blue was now into violence after being fused.
