It speaks in a form of speech unknown to most lifeforms. Its name, as reported by its thrall, translates to Exgal in our tongue.
None known. It seemed to be entirely fixated on corrupting Mezzo and bending her to its will.
☣♪☼•é originally presented itself to Mezzo and attempted to convert her into a thrall on Route 17. It was a partial success; a Team Skull grunt saved her from it, but its poison infected her and corrupted her mind, eventually causing her to develop an obsession with meeting it again. During this time, Mezzo referred to it as "her" but there is no confirmation of a true "gender". It later met with Mezzo again in Haina Desert and successfully fused with her, causing her and her team to fight to protect it. Mezzo was freed from its corruption by a team consisting of Sunny, Freya, Tagg, Vierr, Krieg, and Leeya. It was caught by Tagg using a Beast Ball.
