No Mercy

A series of animated characters from the Undertale universe appear in quick succession, each displaying a distinct, often unsettling expression or pose against a plain background, followed by a bright blue energy burst. The characters include a figure with a red eye and knife, a black and white figure with glowing green eyes, a brown-haired character with a red eye, a character in a green and yellow outfit, and a silhouette with a sword, all set against solid-colored backdrops.
