Cerberio
Cerberio's reveal is one of the few that came with written lore rather than just a cinematic: the official post dates the creature to roughly 700 BCE and describes the three heads switching elements - fire, ice and electricity - during battle.
The same reveal supplies the flavor hook the community latched onto: Cerberio's greatest weakness is itself. The three heads fight over control of the body, making the legendary clumsy - a rare case of an official source pre-writing a boss's personality before launch.
Unlike the four title-card guardians (Rootitan, Victrious, Aquietus, Ropyrus), Cerberio has no known 'Guardian' framing or region attached - it sits in the wider legendary roster, and nothing about its encounter, typing or capturability has been shown.

Why Cerberio stands out pre-release
A tri-element creature is a mechanical outlier in a game built on a 17-type chart: if the head-cycling is a real battle mechanic rather than flavor, Cerberio would change its effective typing or move access mid-fight - something no other revealed Eleon hints at. Whether that translates into gameplay (form changes, rotating movesets, phase-based boss AI) is entirely unconfirmed; the official material describes behavior, not mechanics.
No battle footage, level, moves, stats or region have surfaced for Cerberio, and fan-catalogued details beyond the official reveal are speculation. This page exists because the reveal itself is unusually substantive - it will be rebuilt with verified encounter data at launch.
