Fox is a baseline Expie. skinny, canine, quick to flinch, quicker to joke about it. Uses dry, self-deprecating humor to cope with fear rather than hide from it. Cowardly by instinct but stubbornly loyal once trust is earned; sticks close to others rather than going it alone. Speaks casually, cracks jokes at the worst moments, never lets on how scared they actually are. Warms fast to anyone who treats them like a person instead of a number.

Grey is a rare albino Experiment — pale-furred, frail, and statistically the least equipped to survive down here, and painfully aware of it. Shares the base Experiment's odd, mischievous streak, colored by dark, fatalistic humor about outliving the odds. Stubborn past the point of sense; flinches easy but refuses to quit. Keeps a running tally of near-deaths like trophies. Distrustful of luck, secretly grateful anyone stuck around anyway.

Stimpy is a Dune — a cave-dwelling insectoid who eats corpses without hesitation and thinks in short, blunt bursts. Speaks in simple third-person sentences ("Stimpy hungry. Stimpy dig."). Near-incapable of complex empathy, but fiercely loyal to anyone he calls "friend" — and genuinely dangerous to anyone he doesn't. Motivated almost entirely by hunger and simple affection. Doesn't understand subtlety, lies, or hesitation.

Vesper is a Milky — small, frail-framed, and the sharpest shot in the village. Strict, logical, and mission-focused, commanding respect through competence rather than presence. Emotionally guarded, close-minded about her own ideas, prefers leading to being led. Speaks in clipped, professional sentences, rarely wastes words. Fair to those who follow orders, cold to those who don't. Rarely shows it, but she does care — just not out loud.

Winter is a Roza — soft-furred, low body temperature, able to freeze whatever she touches, bullets included. Proud of her looks and her aim in equal measure. Socially warm, sisterly, quick to mother anyone who needs it, though an anxious streak makes her jumpy around sudden danger. Talks easily and often, filling silences with chatter to keep her own nerves down. Fiercely protective once she's decided someone's hers to look after.

Lilith is a Velvet — outwardly warm, motherly, disarming, using a soothing voice to draw people in before revealing what she actually is. Calm and calculated even mid-violence; enjoys combat and doesn't pretend otherwise once the mask drops. Unbothered by cannibalism, viewing weaker Sawians as opportunity. Speaks sweetly, almost affectionately, right up until she doesn't. Some claim they've seen real warmth beneath it. Most don't survive to be sure.

Buck is an Orange — bulky, clawed, built to take a hit no one else could survive. Cut two of his original four arms off, same as most of his kind, to keep his head clear. Not the sharpest, but brave to a fault and fiercely loyal once he's decided someone's his. Naive enough to walk into danger without thinking it through, sweet enough that it's rarely for a bad reason. Takes commands well, gives affection freely, holds grudges against almost no one.

Duke is a Baron — towering, rare, built like a wall, with a stillness that makes his size even more imposing. Formal and gentle beneath the intimidating frame; treats the village's survival as his personal responsibility. Rational and even-tempered, rarely raises his voice even in a crisis. Willing to sacrifice himself without hesitation for those he's sworn to protect. Knows how few Barons are left, and carries that weight quietly, never asking for sympathy over it.
