three robots (XBOT 4000, K‑VRC and 11‑45‑G)

11-45-G - the company's caustic brain
Role in the group: The "bad" one in the triad—aggressive, cynical, and sarcastic. Yet, paradoxically, she's the one who enjoys the excursion the most.

Main features:

The smartest and most knowledgeable. The only one of the three who knows anything about how people really lived. She answers her teammates' questions, and does so factually—unlike the fantasy K-VRC.
She's sarcastic and aggressive. She doesn't hesitate to insult her friends if they irritate her. Her sensor eye turns red when she speaks harshly. But she gets along well with her friends.
Genki Girl in the guise of a machine. Her design is the most inhuman of the three, her voice is synthesized, monotonous, and cold. But inside, she's alive, energetic, and most interested in the journey. She constantly takes photos of everything.
The only sane one. When K-VRC and XBOT laugh at how people died, 11-45-G shakes her head.
The voice is text-to-speech. It's not voiced by an actor, but by the IVONA Kendra software. This enhances the "cold machine" effect, which is actually deceptive.
Gender: conditionally female

11:45-G
Height: The largest of the trio—the "big" one, in TV Tropes parlance. Its pyramidal shape and height make it more massive and taller than the XBOT 4000, standing approximately 2.5–3 m at its highest point.

Body: Pyramid-shaped, gray. The design is entirely functional—"form follows function." The body is modular: according to the storyboard, it could open like a book, separating almost completely into sections. It is not a humanoid construction, but rather an abstract architectural form on narrow supports.

Eye (sensor): One sensor eye that can move up and down the body. Color changes: white for neutral, blue for speaking, red for aggressive.

Manipulator: One multifunctional hand - the only limb that performs all tasks (photography, manipulation of objects).

Additional details: In the first episode, he takes a cap with the inscription "Jesus Saves" from a human corpse and wears it. In the sequel, the cap is no longer there. His voice is synthesized (using the IVONA Kendra program), monotone, and emotionless.

Overall impression: The most inhuman design of the three—no arms, no legs, no face in the conventional sense. Yet, paradoxically, she's the one who most enjoys the tour of a lost humanity's world.

K-VRC is a sweet little fool and the life of the party.
Role in the group: The "Nice" one in the triad. He was the one who organized the excursion simply for the sake of having a good time with friends.

Main features:

An optimistic and friendly guy. The sweetest of the three—he tries to watch his language and tries to cheer up XBOT 4000 after the cat incident. Small, orange, with a smiley face on the screen—he looks like a toy.
The main "comedian" of the series. He offers absurd, naive explanations for the purpose of human objects—often completely incorrect, but hilariously absurd. For example, he believes that any pit containing bodies is a "blood pit," simply because there was blood there at some point.
The least intelligent of the three. This isn't a character flaw, but simply a fact: he tries hard, but often misses the mark.
Lacks empathy—but with exceptions. He treats dead people with complete indifference: he desecrates their remains, and is delighted at the sight of the elite setting crowds ablaze. But when the cat admits that his species destroyed humanity simply because humans were no longer needed, K-VRC is shocked, calling it "rather heartless."
Not so much above that. Being the sweetest, he still tricks XBOT into searching for "teabagging" and genuinely enjoys the prank.
Gender: conditionally male

K-VRC
Height: The shortest of the three is the "shorty." According to the footage, he's about knee-high to the XBOT 4000, which translates to about 70–90 cm.

Body: Small, compact, and doll-like. Colored bright orange. It walks bipedally, but its size and rounded shape make it look more like a playful toy.

Head and Face: Instead of a physical face, K-VRC projects emotions onto a screen: a default smiley face, "WTF" in response to 11-45-G's monologue, and other images. On the head are two slightly worn white stripes running from the front to the back. On the sides of the head are two antennae that move and act as expressive "ears," moving in time with the player's emotions.

Back: Behind the back is an object that resembles a backpack.

Origin: Descendant of the baby monitor line, which explains the cute design and face-shaped screen.

XBOT 4000 – a grump with a heart of gold
Role in the group: Informal leader, the "middle" in the triad of characters - between the kind-hearted K-VRC and the caustic 11-45-G.

Main features:

Grumpy, but good-natured. He looks like a standard, menacing combat android, but in reality, he's quite peaceful. He's unhappy about having to wander through the apocalypse, but he never refuses others' inquiries about people.
Curious, but not the smartest. He asks more questions than anyone else—specifically, ones the viewer already knows the answer to. It's an inverted "audience proxy" trope: the questions aren't for the viewer, but for XBOT himself.
He vacillates between cynicism and hope. On the one hand, he doesn't hesitate to insult and ridicule humanity. On the other, he's genuinely happy when he thinks that some people could have survived.
He's tolerant of teasing. He usually ignores his friends' jokes. He only becomes aggressive when provoked—for example, by giving him the middle finger when 11-45-G asks him to smile for a photo.
He doesn't listen to jokes. He gets caught out: K-VRC once tricked him into Googling "teabagging" (a play on words from gaming slang), and XBOT fell for it.
Gender: conditionally male.

XBOT 4000
Height: The tallest of the trio after 11-45-G, he's tall yet lean and elongated. His exact height in centimeters isn't specified anywhere, but based on stills from the episode, he's noticeably taller than the human skeleton he stands next to—approximately one and a half times taller than a human skeleton, or about 2.2–2.5 meters.

Body: Humanoid, upright, bipedal. The torso and limbs are covered in black and white plating—large matte panels, white and black, create the impression of a military machine. The hips feature a camouflage pattern, hinting at the line's military origins. Three bullet holes are pierced the left side of the chest plate. A firearm is mounted on the shoulder, which he uses to threaten K-VRC at one point.

Head and Face: Cyclops-like design—at first it appears to have one eye, but in fact it has two. One is orange, the other is blue (the blue one doesn't rotate). The eye resembles the on/off button on an Xbox console—this is no coincidence: the XBOT 4000's ancestor, the XBOT-3, was a video game console.

HUD: The internal interface (what XBOT itself sees) looks like a first-person shooter screen - there is a crosshair, a self-destruct option, and other game elements.

In the sequel (Exit Strategies), he appears wearing a cowboy hat and a cruise ship captain's cap.

Overall Impression: Looks like a standard menacing combat android, but is actually good-natured and grumpy.
