Z2/Personality and characteristics

Unlike Squishy, Z2 greatly distrusts humans. In A Cellular Connection!, Z2 suggested that it and Squishy completely seclude themselves from humankind. When Squishy disagreed, Z2 asserted that humans disrupt the order they exist to maintain, and are a threat to Kalos. It has a blue core, as opposed to Squishy's red core. This distrust was exploited by Lysandre, who gained control over Z2 and used it to attack Lumiose City from the top of Prism Tower. Even after it was freed from Team Flare's control by, Z2 still showed a great amount of mistrust towards humans. It would take the combined efforts of Ash and his friends fighting alongside Alain, Steven Stone, Diantha, the Kalos Gym Leaders, Meyer, and Malva to show Z2 that humans were not disruptions of order, but rather protectors of it.
