User blog comment:TheKnucklesKid123/Sans And Papyrus VS Mario And Luigi/@comment-27928065-20160603221305

OK you really under estimaded the Mario Bros. Even base Mario is MSS in Super Mario Galaxy. That is the same universe. The Mario & Luigi series shows their teamwork, and they are at it. We have never seen Sans and Papyrus fight as a team. Also, Luigi no-doubt defeats Papyrus. Luigi goes to hit Sans, but he dodges it. As he gets up Mario finishes him due to only having 1 HP. Mario could also dodge/survive Sans' attck. OK battle, though.
