Jesus Christ Almighty (Of Nazareth), for some reason, appeared on the Island, and served little bearing on the story (though he WOULD become important under the guise of "Great Sage" in Miitopia) outside of the occasional event he inserted himself into. His most well known action was being a part of the love triangle (or square or...whatever shape it was) between one of the islanders, but this is likely him trying to complicate things and test the mettle of everyone else involved.
