Sans

A skeletal character with a blue jacket and glowing eyes appears in various forms, starting with a calm pose, then shifting to a more aggressive stance with glowing blue energy, followed by a split-screen showing two contrasting versions of the character, one smiling and the other with a menacing grin, before transitioning to a distressed version with a speech bubble and finally a confident, smirking expression. The background changes from white to dark and abstract, then to a split red and green backdrop, and finally to a dark, smoky environment.
