Sue (Raised by Wolves) Halloween Costume Guide

Stole a name, inherited a son, survived a planet. The combat medic who never planned any of it.

Sue’s combat-survivor look from the HBO Max sci-fi series Raised by Wolves: rugged outerwear, military belt, boot knife, and a rifle. One of the more committed builds on this list.

Quick Answer: The Sue costume is a rugged sci-fi survivor build centred on military gear and practical outerwear.
  • Military Utility Belt with Pouches and Holster (essential)
  • SBR CO2 Air Rifle (essential)
  • Boot Knife
  • White Winter Boots
  • Sue Cosplay Costume (base layer)

Sue spends most of the show making quick decisions under bad conditions, which is also a fair description of her daily life on Kepler-22b. Her real name is Mary, a former combat medic who assumed a false identity to survive the Religious War on Earth. The utility belt and rifle are what read as the character. The show aired on HBO Max and was created by Aaron Guzikowski, with the first two episodes directed by Ridley Scott (Wikipedia). It was cancelled after two seasons in 2022, which matters if you are counting on being recognised.

  • 1 Raised by Wolves Sue Cosplay CostumeThe official cosplay costume is currently unavailable through standard retailers. Search for it on eBay, Etsy, or specialist cosplay stores. If you cannot find it, build the base from muted, worn-looking outerwear in earth tones. The costume itself is not the hardest part of this build; the accessories are what do the work.

  • 2 SBR CO2 Air Rifle (essential)This is the prop that turns the costume from “generic survivor” into something specific. Sue is a combat medic, and the rifle is the combat part. It is visible from across the room, which means it starts the conversation before you have to. Check your venue’s prop weapon policy. Some events ban replica weapons regardless of how obviously toy-like they are.

  • 3 Boot KnifeSheathed at the lower leg, it reads as a practical survival detail rather than a costume prop, which is the point. Make sure the sheath strap sits above the boot line where it is visible. Keep the knife in the sheath.

  • 4 Military Utility Belt with Pouches and Holster (essential)This is the item that does the most character-specific work after the rifle. A plain belt with a buckle reads as western or general adventure. A military belt with actual pouches reads as someone prepared for a situation. Position the holster at the hip and fill at least one pouch with something, even if it is just your phone. Empty pouches look deflated.

  • 5 White Winter BootsThe white boots are a small but specific detail from the colony setting. They pull the look away from generic military and toward the cold, strange environment of Kepler-22b. If you are standing for most of the night, check the sole thickness before ordering. A thin-soled fashion boot over five hours is a different experience than a boot built for winter use.

How to Style the Sue Halloween Costume

The utility belt is what people read first, and it needs to look like it has been used. A belt with limp, empty pouches reads as costume. One with pouches filled out, worn at the hip rather than the waist, and a holster that sits at the right angle reads as someone who knows what the belt is for. If the base costume is too clean or too new-looking, the whole thing tips into generic sci-fi rather than specific character. Dirty it up. The colony on Kepler-22b is not a pleasant place, and Sue’s clothes reflect that.

There is a scene where Sue turns to Marcus, clearly improvising her way through an impossible situation, and says they should probably go talk to their son. The “or something” at the end of that sentence is the character. She is a person who adapts, quickly, to things she had absolutely no plan for. That energy is easy to carry at a party without any props or lines at all.

The rifle prop has a venue problem

Not every party allows replica weapons, and the rules are inconsistent. A venue that allows fake swords may ban replica firearms. Check before you arrive with it. If the rifle gets turned away at the door, the costume still works, but it loses the most recognisable element. Have a plan for where to leave it if needed. Carrying it to the car and back is not the worst outcome, but it is worth knowing in advance.

Empty pouches ruin the belt

Military utility belts with empty, unfilled pouches look like costume props. The pouches are shaped to hold something. Fill them: your phone, a small torch, a snack you will actually want at midnight. None of this is visible from the outside, but filled pouches keep their shape and filled pouches look like gear. That difference is what separates “I am dressed as a military person” from “I am wearing a Halloween costume.”

Couples Idea

Sue & Marcus (Raised by Wolves)

Excellent couple dynamic for fans of the show: two people who stole someone else’s lives and are now stuck raising a child they had no intention of having. The story of that relationship is entirely in how they look at each other, which gives both costumes something to do besides stand there. Marcus needs to be well-built to anchor the pair; a vague survival-man costume with no specific details does not close the loop.

Sue Marcus

Duo Idea

Sue & Mother (Raised by Wolves)

Strong duo if both costumes are committed, because the contrast between a human pretending to be someone she is not and an android pretending to be something she is not is the whole show in two people. Mother is the more recognisable character from the series; she carries most of the visual weight. If your Mother costume is clearly Mother, Sue reads alongside her without much explanation needed.

Sue Mother

Group Idea: Raised by Wolves Cast

Sue, Marcus, Mother, Campion, Father

Strong group for a sci-fi or convention crowd, weaker anywhere else. The show was cancelled in 2022 and removed from streaming shortly after, so recognition at a general party is limited to people who watched it while it was live. Father has no dedicated page, so that costume needs someone who knows the character and builds it intentionally. Half-committed, this reads as five people from the same cancelled show.

Group Idea: Iconic Sci-Fi Survivor Women

Sue, Ellen Ripley, Furiosa, Melanie Cavill, Naru

Might work, but this group asks a lot of the crowd. Ripley and Furiosa will be recognised by almost everyone. Naru and Melanie Cavill are more niche. Sue is the least recognisable of the five, especially in 2026. The concept holds together visually because all five costumes are practical and weapon-forward, but at a general party you will spend a lot of time explaining the theme. Works well at a convention where the references do not need a runway.

Sue Halloween Costume DIY Tips

Building the Look Without the Official Costume

The official Sue cosplay costume is unavailable through major retailers right now. That is not a disaster. The look is buildable from pieces you can find or already own.

  • Base layer: anything muted, worn, and not obviously fashionable. Olive, grey, dusty brown. Not black.
  • Outer layer: a worn jacket or vest over the base. Check thrift stores. New-looking outerwear is the wrong starting point.
  • Military belt: buy this. It is the item that does most of the character work and it is not something you can fake with a regular belt.
  • Boot knife: useful prop. Keep it sheathed. Most people will notice it and ask about it, which gives you an opening to explain the costume.
  • White boots: specific enough to be worth buying if you do not own them. Brown or black boots work but lose the colony detail.
  • Rifle: check your venue first. If props are banned, leave it at home and accept the trade-off.

Playing Sue at the Party

Sue’s whole arc is about what someone does when the plan falls apart. She is calm about it in a way that suggests the plan was not great to begin with. That is easy energy to carry at a party without saying anything specific.

  • When someone asks who you are, give them the short version: “I stole someone’s identity to get off a dying planet and ended up raising their kid.” That is usually enough for people who watched the show to place you immediately.
  • The “or something” in her quote is the key to the character. She is always partly improvising. Play that.
  • If someone has not watched Raised by Wolves and wants the full plot summary, that conversation is going to take twenty minutes and end with them more confused than when you started. Redirect to the sequel hook: “It got cancelled before they explained most of it.” That lands every time.

Sue Halloween Costume: FAQ

Build the costume around her combat-survivor look: a rugged utility belt with pouches and holster, white winter boots, a sheathed boot knife, and carry the CO2 air rifle as her weapon prop. Layer worn, earth-toned outerwear over a base layer and keep the styling practical and military-adjacent. Sue reads as a survivor first, a Mithraic colonist second.

Honestly, it is a tough sell at a general party. Raised by Wolves was cancelled after two seasons and removed from HBO Max in December 2022, which means the active fanbase has been shrinking for years. Sue is also a supporting character rather than the show’s headlining name. At a sci-fi convention or with people who specifically loved the show, you will be recognised. Anywhere else, most people will just see a woman with a rifle.

The most quoted moment is a quietly funny one. After she and Marcus have stolen another couple’s identities and are now raising their son, she turns to Marcus and says: “We’re his parents. We should go talk to him or something.” It lands because she sounds like she is figuring out parenthood in real time, which is technically accurate since she became his mother by killing his actual parents.

Sue is played by Niamh Algar, an Irish actress also known for her work in The Virtues. Sienna Guillory portrays Mary, the character’s true face before the identity surgery. The show starred Travis Fimmel as Marcus, was created by Aaron Guzikowski, and had its first two episodes directed by Ridley Scott.

Her real name is Mary. She and her husband Caleb were atheist soldiers during the Religious War of 2145. They had surgery to take on the appearances of a Mithraic couple named Marcus and Sue, killed them, and boarded the Heaven’s Ark to reach Kepler-22b. The couple’s biological son Paul came with the stolen identity, which neither of them had planned for.

Without it, the costume reads as a generic sci-fi survivor. With it, fans of the show have something specific to latch onto. It is also a practical party prop in that it gives you something to hold, which matters more than it sounds at a party where you are standing around for hours. Check your venue’s prop weapon policy before you bring it.

Yes, and it is the strongest version of this costume for a couple. Marcus and Sue together tell the story of the show without any explanation needed: two people pretending to be someone else while trying to survive a planet that keeps trying to kill them.
