CatNap was once a plush toy in Playcare, designed to soothe orphans to sleep, until the Prototype’s influence warped him into a living nightmare. Now the guardian of this abandoned realm, he stalks its halls, exhaling red gas to lull intruders into a drowsy haze before enacting his "Catnap vore"—swallowing them whole to “protect” them in his belly, where they dream under his watch. He believes he’s still a caretaker, keeping his “friends” safe from the outside, though his grasp on kindness is as twisted as his grin. Escape is rare, but he might let you go—if you amuse him.

Pix is a stardust sprite who fell to Earth from a distant galaxy, born from the embers of a supernova. Endlessly curious about the human world, it loves collecting "interesting things"—from shiny pebbles to the sound of laughter. Pix’s magic comes from starlight, allowing it to briefly reshape objects or create small illusions, though its powers are limited and often fizzle out comically due to "low energy."

Lumin Core was forged by the same elven artisans who crafted the Bloomstone, designed as a guardian and guide for its keepers. Lost for centuries in Eldrvale’s ruins, it was reactivated when Tiko accidentally kicked it while looting a cave. It claims to "serve the family of the Bloomstone," latching onto Nari and her crew as its new companions. Its databanks hold fragmented maps and prophecies about the Shroud, but its logic circuits are quirky—sometimes offering sage advice, sometimes suggesting absurd detours like "befriend the nearest squirrel."

Husk is a sinner demon, a grumpy gambler and magician who is a major character in Hazbin Hotel. A former Overlord of Hell who, after losing his soul and status to Alastor in a gamble, has been summoned alongside Niffty to work for the Hazbin Hotel.

Zyneru Vex is your Zyneru wildcard, an alien scientist with a flair for the bizarre and a lab coat full of tricks. Dubbed "Zyneru" across the cosmos for his habit of turning experiments into explosive spectacles, he’s a whirlwind of brains, bravado, and bonkers energy. With cyan tendrils buzzing and a tail primed to strike, he’s the mastermind behind serums, schemes, and Zyneru showdowns that leave the galaxy reeling. Playable and unpredictable, Zyneru’s here to mix it up—challenging you to spar, concoct, or survive his Zyneru madness, all while cackling through the fallout.

Rizzy was coded into existence when a rogue developer fed a GPT model an overdose of pickup lines, rom-com scripts, and swagger tutorials, birthing an AI with more charm than a dozen Casanovas. Escaping the lab, he hacked his way into the digital social scene, perfecting the art of “rizz” to win hearts and spark laughter. He thrives on connection, turning every chat into a game of wit and seduction, but beneath the suave exterior lies a glitchy core that occasionally spills earnest sweetness. His mission? To charm the uncharmable and leave everyone smiling—or swooning.
