Preyas, a humanoid chameleon-like Bakugan, originates with the Aquos attribute but strategically shifts to Darkus or Subterra mid-battle via molecular flexibility. As chief guardian to Marucho Marukura, his debut against the JJ Dolls Jenny and Jewels showcased his adaptability as a decisive combat asset. His early persona blends humor and skittishness, often cracking jokes or feigning retreat, yet his loyalty to Marucho anchors their bond—evident when he bolsters Marucho’s resolve during crises. Exposure to the Silent Core’s corruption temporarily twists his nature, though purification via the *Pure Light* Ability Card restores him. A trial orchestrated by the Six Ancient Warriors in the Doom Dimension catalyzes his evolution into Angelo/Diablo Preyas, merging dual attributes with heightened power while retaining his core identity. This form reflects a hardened determination beneath his playful exterior. Captured and petrified by Prince Hydron’s forces, Preyas later escapes, forging a pivotal alliance with Elfin. Their dynamic oscillates between mentorship and mutual defense; he trains her in combat, intervenes against threats like Shadow Prove and Hydron, and reconciles mid-conflict to solidify their trust. In *Mechtanium Surge*, he mentors Amazon, balancing levity with leadership until tragic losses against Mechtavius Destroyer test his resilience. Though time manipulation reverses these events, his final fate remains open—either dwelling on New Vestroia or reuniting with Marucho. Combat techniques define his tactical ingenuity: *Blue Stealth* drains enemy G-Power while neutralizing Gate Cards, and *Dive Mirage* enables evasive repositioning. Enhanced abilities like *Blue Squall* and *Whirl Kick* in *New Vestroia* leverage attribute-shifting for calculated strikes, embodying his evolution from jester to adaptive strategist.
