1. Alpha sans. First appeared in the forest outside Snowdin Town. Depending on the player's actions, he will become a trustworthy friend or a fearsome hero-like opponent. He is the final BOSS of the massacre route, and the game is extremely difficult.

2. Almighty Sans Sans has been nerfed, otherwise she would be ranked first. In addition, she is not omnipotent, but is 30 times stronger than Sans.

3. Error404 seems to be the creator of errorsans, a being that errorsans are still afraid of, one of the strongest ones, etc., error404 is not number one? So who is the first? That's right, he is the billsans who is loved by everyone, whose AU is shattered, and who runs away at the speed of light from 800 miles away!

4. Billsans. Can use all consciousness-like attacks and abilities, for example: he ignores Lian Lian's unconscious level ability and can use his unconscious level ability to play Lian Lian. You can control the space and time code at will, break the fourth wall, and ignore the personality (it seems to need to be activated).
