Ultimate Story
Riven made his first appearance with the other specialists at the very end of the Ultimate Story special: The Celestial Winx. Many ago, he lived around the era that the Original Celestial Winx did. He also witness his girlfriend, Musa, graduated with her friends and then moved up to become one of the servants of the Great Wizard as a member of the Celestial Winx. The girls were sent off on their first mission to find and defeat Malicet, with Riven and the other guys watching them depart, awaiting their return.

However, the girls couldn't defeat Malicet and were forced to sacrifice themselves. When the Great Wizard delivered the news about the girls' sacrifice, Riven as well as the other guys were greatly furious towards their master for allowing the girls to fight a massively dangerous entity and made a rigorous trek to meet with the Enchantress of Magix so that they could find a way to reunite with their girlfriends.

When they arrived to meet with the Enchantress, they made their wish to reunite with their girlfriends. She mentioned to them that there was no way they can reunite at the moment. However, there was one way that they can: she needed to put their entire realm in a cryo-status until the Celestial Winx were to return. Desperate to see their girlfriends again, they conceded and had her put all of their worlds into a status that lasted for 4000 years.
