A Leprechaun has not been seen in an episode.
After Dyson told Bo to not hold back and take what she needed to sex-heal with him, he looked exhausted; and when Kenzi told him that he looked "kinda green", he joked that he was a quarter leprechaun.
A leprechaun is a type of fairy in Irish folklore, usually taking the form of an old man, clad in a red or green coat, who enjoys partaking in mischief. Like other fairy creatures, leprechauns have been linked to the Tuatha Dé Danann of Irish mythology. The Leprechauns spend all their time busily making shoes, and store away all their coins in a hidden pot of gold at the end of the rainbow. If ever captured by a human, the Leprechaun has the magical power to grant three wishes in exchange for their release. Popular depiction shows the Leprechaun as being no taller than a small child, with a beard and hat.
