Karmic Retribution[KR]: A side effect of Sans' attacks, Karmic Retribution acts like a poison for the soul, whittling down an enemy's health once Sans hits them. While it only drains a little at a time, its drain increases based on how many sins the opponent has committed.[KR]:

Glowing bones[G]: (Sans can summon large groups of them easily and with great speed, making them harder to predict and dodge by comparison. it goes through everything. can't be broken)

Bones: (Sans shoots bones the opponent if gets hit it will get stuck where it hit is continues damaging the opponent until it gets out or disappeared and have knockbacks. can break and ricochet.)

Blue bones[B]: (Sans can summon blue bones that only damage people if they're moving when they touch the bones.)

Gaster Blasters: (Portable laser cannons shaped like dragon skulls that Sans can summon at will. They levitate off the ground and fire at Sans' will, and Sans can summon as many as he wants.)

Coloured Gaster Blasters[C]: (Same as Gaster Blasters, But Coloured Ones have knockbacks.)

Soul Manipulation[Telekinesis]: (Blue Mode: Another of the skeleton brothers' signature attacks, Blue Mode grants Sans the ability to make enemy souls affected by gravity. While affected by Blue Mode, enemies have their movement heavily restricted, and are only able to jump to move. Sans can also use this to telekinetically lift and move his opponent, letting him slam them around with his mind.)

Teleportation[Shortcut]: (Sans obtained the ability to teleport, which he often uses as a shortcut to get places quicker. However, in battle, Sans uses it to move his foe straight into a new attack once his old one ends, making him far more unpredictable. Blinds the opponent a few seconds if they look at Sans.)
