The character known as Elisio is the Italian localization name for Lysandre, a significant figure appearing in the narrative of Pokémon: Mega Evolution Special IV. He is the president of Lysandre Labs, presiding over the large research facility with a commanding presence. He demonstrates a complex and manipulative nature, presenting a public persona of a benefactor who supports research for peaceful purposes and the well-being of Pokémon. He provides a Trainer with a Mega Ring and Charizardite X, challenging him to defeat ten Mega Evolution users in consecutive battles to prove his strength and protect what is important to him, under the condition that failure would result in the confiscation of these items. Privately, his motives are questioned by others, including a member of the Kalos Elite Four, suggesting a deeper, more ambiguous agenda. He takes a particular interest in the protagonist's strength and mastery of Mega Evolution, overseeing the grueling challenge he designed. His facility houses a secured containment unit for a powerful ancient artifact known as the Giant Rock or megalith, which is described as possessing massive energy. He claims the energy-containment chamber is necessary to prevent a catastrophic event similar to one that previously occurred in the Hoenn region. When a Trainer's Chespin becomes mysteriously ill and falls into a coma after an incident involving unknown, blob-like creatures within his labs, he publicly vows to use all available resources to help it recover and sends the protagonist on a mission to complete the Mega Evolution system to find a cure. This event is connected to secret experiments conducted by scientists within his laboratory on small, green, blob-like creatures referred to as "Zygarde" cells or cores, which resulted in the energy-based injury to the Chespin. His character has connections to broader media, where he is identified as the leader and founder of Team Flare, an organization with the goal of using an ultimate weapon to eliminate life and create a world only for its chosen members. He is also a descendant of the ancient king of Kalos, AZ.
