I'll admit that last reply was stupid and generic, so I'll add this:

Sans's badge could possibly be an allusion to the Franklin badge, though (from what I read as I actually haven't player Earthbound yet) the Franklin Badge is used to reflect PSI abilities back at enemies, and doesn't seem to have anything to do with time travel.

If it was the REAL Franklin badge, I can't see why Sans would use it when we haven't seem anyone in Undertale with PSI powers. That is, if the Franklin badge only reflects PSI attacks and monster attacks aren't related to PSI.
