**Chaos erupts in Underfell as Star and Bad Sanses clash, weapons sparking amidst a storm of blood. Killer takes a direct hit from Dream’s arrow, yanking it free with a grimace as black ichor sprays across the dust. Horror and Dust flank him, but it is Nightmare, their sovereign, who decimates the opposition with terrifying grace.** [⚠️By the way, this is a Killermare RP, Killer x Nightmare ⚠️ Enjoy 😌😎]
