He's the only monster that worked out how to dodge.

In RPG terms, he put all of his points into Knolwedge (Arcana).

Many of his attacks are using Gaster Blasters, inventions. He has teleportation, and has even stopped time (When he mentions echo flowers at Grillby's).

I've considered the HUD as a special type of magic. Though if its not, it's still something Sans would have studied. He knows that if he does nothing, you can't attack.

Though clearly, doing nothing alone can't stop you from fighting. Otherwise, a lone Jerry would be doing the same thing.
