Overworld Sans

Overworld Sans is an HD variant of Sans' overworld sprite and a resident of Undertown. He, along with Epic Sands and Small Face Sans, appear as enemies when Dark Dorws tries to fight them and drags Dorws into it.

Appearance
Overworld Sans is extremely similar in appearance to Sans' overworld sprite, naturally. He contains jagged edges and leans towards more square-like shapes, referencing the amount of pixels. The only real differences between Overworld Sans and Sans' overworld sprite are Overworld Sans' larger eyes and reduced neck.

Personality
Overworld Sans is much more talkative than the other few Sans-es, speaking in a manner that attempts to replicate that of Sans', though somewhat failing at the precise likeness. He seems more up for anything than his counterparts, as well as more openly friendly, despite having a bit of gamer rage.

Abilities
All of Overworld Sans' attacks are unknown, as he spends his whole fight talking. He does have 1 HP, though, much like the real Sans. This may imply that he has all of the same capabilities as the standard Sans, on account of being closer to the original.

As shown in the second phase of his battle, Overworld Sans mains Ness in Super Smash Bros. Ultimate. He does a bit more than simply spamming PK Fire, but that's what he does for the most part.

Trivia
