7 Must-Catch Early Game Deviants in Once Human (2026 Edition)
Once Human deviants boost survival and sanity for new players; Extradimensional Cat, Chefosaurus Rex, and Butterfly's Emissary are vital.
I still remember my first few days in Once Human, fumbling through a world that seemed determined to kill me at every turn. Looking back now in 2026, with seasons and expansions I've lost count of behind me, I'm almost nostalgic for those early struggles. The deviants I captured back then may have looked simple on the surface, but each one was a tiny lifeline that kept me sane—literally, in some cases. The funny thing is, even after all the updates, these same creatures still form the backbone of any new player's survival strategy. Let me walk you through the ones that helped me the most, because trust me, you don't want to skip them.
The Extradimensional Cat – Your First Step Toward Sanity
This little floofball was the first deviant I ever caught. I found it just outside a settlement, sitting there like it owned the place. And honestly? Once I put it in a containment unit back at my base, it really did start calling the shots. Every time I stumbled home covered in pollution and on the edge of a mental breakdown, the Extradimensional Cat would hop onto my bed and snuggle right up. That sleep buff felt like a warm hug, speeding up health regen and purging the insanity effects. Late-game players probably have fancier companions, but for a newbie, this cat is a godsend.
I have to admit, back then I thought, "Is this really it? A pet that just cuddles?" But I was wrong. The early game throws so much horror at you that having a reliable way to shake off madness is worth more than any weapon. Once you have better gear, you might free up the unit, but never look down on that first cat.
Chefosaurus Rex – The Kitchen Sidekick
Remember the quest "There's A Dragon Here" from Lowe at Meyer’s Market? If you haven't done it yet, stop what you're doing and go get this guy. Chefosaurus Rex looks like something out of a Saturday morning cartoon, but he's dead serious about cooking. I placed him in my territory and suddenly my crafting costs for food and drinks dropped, and the cooking speed felt like I'd hired a gourmet robot. In those early days when every scrap of material counted, this dino probably saved me hours of grinding.
Will he stay with you forever? Probably not. By the time I was running high-end recipes, I'd swapped him out for something more specialized. But for getting your food production off the ground, he's brilliant. And let's be honest, feeding yourself efficiently is half the battle in Once Human.
Butterfly's Emissary – Your First Combat Buddy
The game hands you this one during the tutorial, and I won't deny I was skeptical. A glowing butterfly that floats up to enemies and slaps them? Come on. But in those terrifying first hours, when a zombie-looking thing had me cornered, the Emissary would zip in and deal just enough damage to let me breathe. It ran out of power fast, sure, but it popped out again after a short rest in my backpack cradle.
I replaced it with a Zeno-Purifier later on, but for a long time, the Butterfly's Emissary was my only real combat companion. Don't underestimate how much a little extra DPS matters when you're learning the controls and every enemy feels like a boss.
The Logging Beaver – Your Lumberjack on Four Paws
I found my first Logging Beaver near a dock, gnawing on a stick with the most serious expression I'd ever seen on a rodent. I scooped him up, not really knowing what I'd get, but soon he was running around my base collecting wood. He can even man the advanced logging structure once you unlock it, which feels like having a tiny employee who never asks for pay.
Now here's the catch: the little guy is not fast. By the time I had an alloy axe, I could chop down ten trees in seconds and look back at the beaver still ambling toward the first pile. In the early game, though, every log matters, and he was a steady source that let me focus on other things. If you're just starting out, don't skip him, but prepare to graduate to better sources once you hit the mid-game.
Digby Boy – The Little Miner That Could
Digby Boy works just like the Logging Beaver, except he brings you ores instead of wood. I found mine while mining some silver—there's a higher chance from rarer nodes, so keep an eye out. He scurries around, gathering iron, copper, occasionally even silver, and he can also hop onto the automated mining platform later on.
Similar to the beaver, his output isn't going to blow your mind. Once you have high-end tools, you'll collect more in a minute than he does in an hour. But in those formative days? He was a constant trickle of resources that let me upgrade my gear without spending all my time on resource runs. Pair him with the Logging Beaver and you've got a passive income of basic materials that feels downright luxurious.
Zeno-Purifier – Your Teleporting Bodyguard
If Butterfly's Emissary was the tutorial friend, the Zeno-Purifier was the first real warrior I unleashed. This samurai-looking deviant doesn't just float—it blinks straight to an enemy and starts carving them up. The damage is noticeably better, and the teleport effect means it's never stuck on terrain. I unlocked mine naturally through season goals without even trying, and the moment I swapped it in, combat felt completely different.
For the longest time, Zeno-Purifier was my go-to combat deviant. I'd argue it's the best you'll get before you reach the point of chasing a Dog's Skull. If you're reading this as a newcomer, aim for this one as soon as the season goals let you. You won't regret upgrading from that butterfly.
The Electric Eel – The Mighty Generator Boost
Now this one? This is the real treasure. The Electric Eel can be caught while fishing, even by absolute beginners. I hooked mine during a quiet evening at a pond, and it's been in my base ever since—well, one of them. Because here's the kicker: it boosts the power output of a generator, and yes, you can farm multiple Eels to boost multiple generators.
I can't stress enough how insane this is. Early on, you're always wrestling with power shortages, and a single Eel can make a tiny generator feel like a powerhouse. Even at the late game, most veterans keep a few of these in their bases to optimize their power grid. If you only take one piece of advice from me, let it be this: go fishing, and hope for an eel. It'll carry you through the entire game.
The deviants I've talked about here haven't changed dramatically since 2024, and that's part of their charm. Once Human has grown and evolved, but these early-game allies remain as reliable as ever. They taught me patience, resourcefulness, and the strange comfort of having a pixelated creature on my side. So go ahead, new survivor—grab that cat, befriend that beaver, and never underestimate the power of a good night's sleep. You'll thank yourself later.
