Asgore is secretly Sans

Proof: they are both the final bosses of two different routes(not counting Photoshop Flowey).

Sans and Asgore both like Toriel.

Theory: Asgore is disguising himself as Sans to win back his Ex-wife. Knowing she loves puns, he concocts an entire persona around making stupid puns.

Oh, you say, but they were in the same room at several points in the game's true pacifist ending?

Sans is really just a lifeless costume, and since it doesn't have lips, Asgore can use his ventriloquism skills to make it appear like Sans is alive.

At one point Asgore has a blue eye turing his boss battle. Ditto for Sans. sans' boss fight is just Asgore manipulating a puppet using magic.

Also Undyne is the Pope
