Qilby made his first appearance in season two as the hidden main antagonist. He was accidentally summoned from the blank dimension when Yugo tried to harness the power of the Eliacube, when he came to the World of Twelve he explains the origins of his species through half-truths and sent Yugo on a quest to acquire the Dofus (dragon egg) of his sister dragon, Shinonome. His true plan is eventually revealed that the quest was largely to distract Yugo so he could regain his power, steal back the Eliacube and then absorb the Wakfu of the planet to power his ship so he can continue to explore the Krosmoz (the process would destroy the planet). After his battle with Yugo and the Eliatrope children, he was stripped of his powers when Shinonome unleashed a powerful blast of Stasis energy from within her dofus. Now helpless and powerless, Qilby was banished to the Blank Dimension again by Yugo. Despite his pleas that he'll grow crazy alone again, Yugo ignored his pleas and tells him that he is already crazy and alone and left Qilby in the Blank Dimension.
