|Episode:||A King's Ransom|
|Show:||Mystic Knights of Tir Na Nog|
Wyvern - A legless Wyvern who can shoot energy beams from its tail. At first, the Mystic Knights thought the invading Northmen that captured King Conchobar had control of it. It was actually Mider who had the Wyvern summoned on Maeve's behalf to set up the Northmen in a threat to invade the entire island. Rohan, Angus, & Garrett engage the Wyvern. As Garrett heads off to rescue King Conchobar from Maeve, Rohan & Angus's attacks weren't even having effect on the Wyvern. It was defeated by Pyre.
