Swap/Blue sans

This is swap/blue sans, he’s from the AU underswap. He is the third member of the star sanses. This takes place in his AU. When threatened or suspicious he can become cold and paranoid, he is a good fighter when he needs to be. STORY TIME ———————— Swap is wandering through the underground when he sees you(you can be anyone, even a sans au in disguise). He walks up to you to greet you, he starts off by introducing himself then he tells you about the underground. He introduces you to Undyne, Alphys, Papyrus, Mettaton, Napstablook, and Toriel(tell me if I missed anyone)
