Once Human Characters Guide: Veronica

Veronica

A researcher from the Mayfly, who assists the awakened player escape from Rosetta’s attack in the initial plot of the game, and helps the player gradually get to know the world. She is cheerful and enthusiastic, believing that the power of players can bring about positive change for the world. In the process of escaping with players, she is attacked by Rosetta. Now her life is uncertain.

  • Faction:

Veronica is one of those Once Human characters who keeps you guessing—and that’s exactly what makes her so memorable. Depending on where you meet her or what you’ve done, she can swing between helpful ally and relentless adversary. She’s not the type to stay neutral. That unpredictability gives her a unique presence in the game’s world, and it’s likely tied to how Once Human blends survival mechanics with branching storylines. 

Her allegiance isn’t tied to any one faction, which makes Veronica particularly interesting within the broader scope of the Once Human Characters Guide. Whether she ends up assisting you or sabotaging your every move may depend on your actions, your chosen faction, or some deeper part of the story yet to be uncovered. If you’re aligned with a group like the Mayflies or clashing with Rosetta, Veronica might play off those dynamics in unexpected ways. 

There isn’t much official detail on her origins, goals, or where exactly she fits into the scenario-based structure of the game. Still, she’s clearly designed to be a wild card—someone who can tip the balance of a mission or storyline. Players should treat every encounter with Veronica as a potential turning point. In a game where every decision matters, she adds just the right amount of tension. That’s why understanding characters like her is just as important as knowing the major players in the Once Human Characters Guide.

Once Human Characters Guide: Victor

Victor

Victor is one of the founders of the Mayflies and also a member of “The Nine”. He holds the power to transform the physical body into energy. In game, he acts as the guide and survival partner. During the adventure, he will gradually impart his knowledge to players. Players can also learn about the thrilling story behind the Mayflies through him.

  • Faction:

Victor Hammett isn’t just a name buried in the lore—he’s the backbone of one of the most important Once Human Characters in the game. Once a loyal Rosetta insider, Victor’s arc is one of rebellion, redemption, and reinvention. He saw firsthand the cost of Rosetta’s obsession with stardust experiments and deviants, and it broke him just enough to push him toward something better. His encounter with Mitsuko sparked a turning point, and from that, the Mayflies were born—a faction dedicated not to domination, but to coexistence. 

As the architect behind the Mayflies, Victor’s hands are all over the Once Human Characters Guide. He helped develop the cradle and containment units, giving the Mayflies the tech they needed to survive and push back against Rosetta’s tyranny. His falling-out with Mary, once his comrade in Rosetta, paints a clear picture of the game’s deeper ideological divide. Mary believed in absorbing deviants; Victor believed in saving them. It’s a clash of philosophies that makes the faction conflict in Once Human more than just PvP—it’s personal. 

But Victor’s journey didn’t end with his rebellion. In a strange twist, Mitsuko saved his life by transforming him into a bird-like being known as V. He lost parts of his memory in the process, which adds an air of mystery and tragedy to his role. Still, even in this new form, Victor remains vital to the Mayflies’ identity and cause. His story, threaded throughout the Once Human Characters Guide, makes him more than a quest-giver or backstory NPC—he’s a symbol of the struggle for a better future.

Once Human Characters Guide: V

V

V is the presumed deviation of Victor Hammett. A mysterious avian companion with a sharp wit and sharper eyes, V. serves as the player’s guide through the fractured world of Once Human. Perched on your shoulder—literally or metaphorically—V. delivers cryptic insights, sarcastic commentary, and surprisingly useful advice.

  • Faction:

V is one of the more mysterious figures in Once Human, and that’s saying something in a world filled with mutated horrors and post-apocalyptic cults. At first glance, he’s just a talking bird who drops by to hand out quests and glide mechanics—but if you dig deeper, you’ll realize V is actually the transformed form of Victor Hammett. Yes, that Victor—the founder of the Mayflies and a central figure in the Once Human Characters Guide. His transformation into V is never clearly explained, and that’s by design. It’s a puzzle the game hints at without solving, adding a layer of mystique to an already pivotal character. 

From a gameplay standpoint, V plays a vital support role. After being sent by Mitsuko to investigate a missing butterfly, he ends up trapped in the player’s cradle, where he becomes a kind of companion. Players can summon him by long-pressing the summon button, unlocking weekly commissions that are a major XP source. With enough tasks done, players can rake in around 13,000 XP, making V not just a quirky side character, but a reliable grind-saver. He also enables special gliding, which adds serious mobility when combined with the Speedy Module. For those who’d rather swap him out, the Rosetta Exploration Drone offers an alternative glide style with different pros and cons. 

V’s role in the Once Human Characters Guide helps underline how identity and transformation echo throughout the game’s story. From leading a faction to being reborn as a bird, V represents how the past doesn’t always die—it adapts. Whether he’s handing out side missions or silently carrying the burden of Victor’s fractured memory, V reminds players that even in a world torn apart, who you were still shapes who you become. And that idea fits right in with the core of the Once Human Characters Guide.

Once Human Characters Guide: Mitsuko 

Mitsuko

Mitsuko is a composed and intelligent scientist deeply involved in Stardust research. She approaches problems with precision and rarely lets emotion cloud her judgment. Though often reserved, she genuinely cares about the fate of humanity and believes knowledge is the key to survival in this fractured world.

  • Faction:

Mitsuko is one of the most important Once Human characters, acting as a central figure in both the story and the player’s journey. As a powerful metahuman with the ability to generate deviations, she represents a turning point in humanity’s struggle against corruption and control. Her earliest creation, the Paper Butterfly, marks her role as both a scientist and survivor. With a tragic past involving Rosetta’s experiments and the loss of her family, Mitsuko carries the emotional weight of the story and motivates players to understand what’s truly at stake. 

She co-founded the Mayflies alongside Victor Hammett, building a faction rooted in the hope that deviants and humans can live together. This resistance group stands as a counterforce to Rosetta’s brutal experiments and the cold ambition of the Evolutionists. In the Once Human Characters Guide, the Mayflies’ ideals directly reflect Mitsuko’s journey: she’s not just fighting for survival, but for a future where no one is treated as a monster. Her ability to detect subtle changes in stardust makes her one of the few people capable of understanding the deeper anomalies threatening the world. 

Mitsuko often appears in key story moments, offering guidance, upgrades, and emotional clarity. Whether you’re meeting her through a memory echo or fighting alongside her in a monolith showdown, she anchors the narrative and reinforces the moral divide laid out in the Once Human Characters Guide. With her living in a subspace to avoid detection from the Great Ones, Mitsuko’s presence blends myth with science. By the end of the main story arc, her decision to return memories to Blackfall’s residents highlights just how deeply she’s tied to the player’s purpose. For those diving into the Once Human Characters Guide, Mitsuko is more than just a supporting character—she’s the soul of the resistance.

Once Human Characters Guide: Pauline

Pauline

Pauline is a restaurant owner in Blackfell. A pragmatic and resilient survivor, Pauline helps manage operations at a local shelter. Though quiet at first, she’s a key figure in keeping hope alive amid the chaos.

  • Faction:

Pauline is one of those wildcard Once Human characters—the kind who can smile at you in one scene and sabotage your mission in the next. She’s mentioned as someone who may either help or oppose the player, which already tells you she’s got her own agenda. Whether that makes her a double agent, a pragmatic survivor, or just someone with shifting loyalties is still up in the air. What’s certain is that if Pauline shows up, don’t assume she’s there to make your life easier. 

Her ambiguous role adds an interesting twist to the Once Human Characters Guide, where most characters tend to fall clearly into one side or another. Pauline’s unpredictable behavior forces players to stay alert and question their assumptions, which fits the game’s larger theme of moral gray areas. In a world where factions like the Mayflies, Evolutionists, and Rosetta all have conflicting goals, someone like Pauline can be both an asset and a threat depending on the day—or the hour. 

Even without detailed backstory, Pauline’s inclusion in the Once Human Characters Guide shows how important it is to consider the human element behind each group. Once Human Characters are made of people, and people are complicated. So whether you meet Pauline as a guide, a saboteur, or something in between, remember that trust in Once Human isn’t a given—it’s earned. Or lost. Quickly.

Once Human Characters: Mary

Pauline

Mary is a member of “The Nine”, one of the most powerful Meta-Humans, ranked No.8. Because of the abnormal “Impure” in her body, she has obtained the power of a Beyonder, and can release a large number of deadly toxins, which is extremely destructive. As head of Rosetta’s Special Response Team, Mary conducts an endless hunt of Mayflies and the Meta-Humans who want to escape from Rosetta’s control.

  • Faction:

Mary. Among the diverse cast of Once Human characters, Mary stands out as a determined and compassionate figure navigating the chaotic post-apocalyptic world. Once a field medic before the collapse, she now serves as a vital support to the Awakened, patching wounds and lifting spirits in equal measure. Mary is known for her relentless optimism and calm demeanor even in the face of mutated horrors and twisted remnants of humanity. While others may have hardened completely, she holds onto empathy like a lifeline, often reminding those around her of what’s still worth fighting for.

Like many Once Human characters, Mary’s backstory is layered with loss and resilience. Her experiences on the front lines, both before and after the emergence of Stardust, have given her a sharp sense of reality—yet she chooses kindness over cruelty. Mary often acts as a moral compass within her group, and while she may not wield the most powerful weapon, her presence is stabilizing and essential. In a world ruled by chaos and corruption, characters like Mary represent the fading, fragile light of humanity.
