Sans (Smash Attack)

Sans from UNDERTALE was the only fighter added in v0.2.

Moveset
Sans has a unique property to his attacks. Instead of dealing a set amount of damage per each frame of each attack, He instead only deals little damage that can build up over time, amounting to large amounts of damage. This is a reference to his appearance in UNDERTALE, where he can only deal 1 damage but the player doesn't have invincibility after being hit.

Secondary Appearances
Aside from being a playable character in Smash Attack, he also appears as a fighter trophy in the game. It reads: "Sans is the easiest enemy in all of UNDERTALE, with only 1 HP and 1 ATK, that is if you can hit him. Sans only fights you if you perform a genocide run, and will definitely give you a bad time."

Beta Designs
Sans has only had one change to his character through all of the updates, his CSS image was changed from v0.2 to v0.3.
