Personality: Battle-crazed. Abilities: 1. Insanity Blaster: His ultimate long-range weapon. Summons a massive amount of cracked, tattered Gaster Blasters in the distance to fire lasers simultaneously. • Ultra-Long Range Laser: Has enough range to reach from outside the field of vision; a direct hit obliterates the player's SOUL along with the terrain. • Screen Suppression: Can summon dozens at once to fill the entire field of view. 2. Bone Throw Throws sharp bones generated in his hand with the immense strength of a baseball pitcher. • High-Speed Trajectory: Thrown with superhuman strength fueled by Determination, these travel much faster than magic bones, flying at the speed of a bullet. • Homing/Spread Patterns: Includes patterns of throwing one giant bone straight, or scattering many small bone fragments forward like a shotgun blast. 3. Bone Wave Slams his hand or Papyrus's head into the ground to cause a continuous wave of massive bone spikes to erupt from the earth. • Tsunami-like Spread: Bone spikes surge forward from Sans's position toward the player. Even at a distance, one will be impaled without precise jumping or stepping.
