Card Appearances:Adar - Rhiannon the Quelled Supernova

Appears in Leap 005 - The Adar of the fanfic "Have no Fear" by Karkashan. This card is played by the manifestation of Reggie Mackenzie's insecurities, who had taken on the form of a crazed man at the time. She is Xyz Summoned by overlaying "Adar – Llinos the Solar Flare" "Adar - Haf the Longest Day" and "Adar - Cadfael the War Shimmer". Destroying Zeradias as a result of battle, her effect is used during the End Phase to bring him back on the manifestation's side of the field.

However, once Reggie regains the ability to see her monster cards, she brings forth Master Hyperion. Using his effect to destroy the Sanctuary in the Sky, she kills off Zeradias as a by-product. Immediatly afterward, she calls upon her Master Hyperion to attack Rhiannon with his attack, "Solar System Decimation", destroying the Psychic Xyz monster and setting the manifestation up to take a direct attack by her other monster on the field, Avenging Knight Parshath.
