In this au, sans can only use a fraction of his blue eye power so both of his eyes are blue and all the souls are possessing his attacks to make him stronger to stop the human. So his bone attacks are rainbow while having a rainbow glow to them. His gaster blasters are blue and blast a rainbow beam at you and every time he gets hit, one of the souls go inside of him so he doesn't die until you kill all the souls and his soul.
Next is the yellow soul.
