This is a concept drawing of something I'm working on a zoro blackstar battle made through unitale

the encounter with zoro for genocide runs zoro stands in your way enraged and determined to kill the genocider wielding his fathers magic he has copied every single monsters attacks you have killed and will now make you pay for your sins.

Everyone can see iconic moves here like Asriels chaos sabers or sans Gaster blasters but Zoros signature attack is BlackStar judgement a form of magic that grows stronger with ones determination it crashes down on the battlefield and unleashes a randomized barrage of copied attacks upon explosion

Zoro BlackStar belongs to me
Undertale belongs to Toby Fox
