Mystic Knights of Tir Na Nog is an Irish/American fantasy-adventure television series set in a fantasy version of ancient Ireland, created by Saban Entertainment. It aired on the Fox Kids Network from September 12, 1998 and ending on May 7, 1999. There are a lot of weird things about Mystic Knights of Tir Na Nog but as an attempt to replicate the success of Mighty Morphin Power Rangers but do it completely in-house, it was a failure.
