We are the wolves.' He says it at Mount Rainier National Park, alone in the woods with his little brother. He means it completely.

Sean Diaz Life is Strange 2 Wolf Squad Dontnod

1 Wolf Squad Hooded Sweatshirt (essential)The hoodie is the costume. Sean wears it through most of the game, increasingly patched and worn by Episode 3. The WOLF SQUAD text across the chest is what makes the look recognizable to anyone who has played Life is Strange 2. If the text is too small to read at arm’s length, it will not register at a party. Everything else in this build is secondary to getting this item right.

2 Brown Suede JacketSean picks this up in Episode 2 and wears it open over the hoodie. It changes the silhouette from teenager in a hoodie to teenager who has been outdoors for several weeks. Any worn-in brown jacket in a similar cut works here.

3 Grey JeansCheck your closet first. Any plain grey jeans or khakis in a similar shade work.

4 Military BackpackSean carries a green hiking backpack for most of the game, given to him in Episode 1. He decorates it with patches along the journey. A military or hiking backpack in olive or khaki is accurate. If you have time before Halloween, a few iron-on patches make it look like it has been somewhere.

5 Brown BeltSean’s belt strap hangs slightly loose from under the hoodie. Check your closet. Any plain brown belt works.

6 Burgundy Knit Beanie (essential)Sean wears a maroon beanie in Episode 1 and it stays in rotation throughout the game. Paired with the Wolf Squad hoodie, it is the combination that makes the costume read as Sean Diaz rather than just a teenager at a party. The dark red color matters more than any specific logo on the beanie.

7 Brown High Top SneakersSean wears running shoes in Episode 1 and switches to hiking boots in Episode 2. Brown high tops split the difference and are more practical for a full night at a party.

How to Style the Sean Diaz Halloween Costume

The hoodie text is the first thing people read, and it needs to be legible from a few feet away. Faded or small print at party distance collapses the look into “teenager in casual clothes,” which is what most of the people at the party are already wearing. The jacket stays open over the hoodie. A backpack that still looks packaged will undercut everything else in the build — something scuffed and worn does the work a new one cannot.

Before any of this, Sean practices what to say to a girl named Jenn in his bathroom mirror. He gives himself notes. He is sixteen and nervous about a party. Three days later he is somewhere in the Pacific Northwest with his little brother, no phone, and a kid who just discovered he can move objects without touching them. He adjusts.

Order the hoodie early and check the text size

There are multiple Life is Strange 2 hoodies available and they are not all the same. Some have WOLF SQUAD in large block letters across the chest. Others have a small version on the sleeve or above a pocket. You need the large chest version for the costume to read at a party. Zoom into the product listing photo before buying and order at least two weeks before Halloween so you have time to swap if it is the wrong version.

Add patches to the backpack before you go

In the game, Sean’s backpack fills up with patches and small souvenirs across five episodes. A plain military backpack is accurate but three or four iron-on patches make it look like the actual bag from the game. They do not need to match the in-game designs exactly. Wolf imagery, road signs, or anything that looks handmade and well-traveled will work. It also gives people who know the game something to ask about.

Sean Diaz Group Halloween Costume Ideas

Couples Idea

Sean Diaz & Cassidy (Life is Strange 2)

Might work, but the relationship is player-determined in the game, so not everyone who played it chose the romantic path with Cassidy. Outside the Life is Strange fanbase, the pairing reads as two teenagers in casual clothes. This lands better at a gaming event than a general Halloween party, where the context to make it meaningful simply will not be there.

Sean Diaz Cassidy

Duo Idea

Sean Diaz & Daniel Diaz (Life is Strange 2)

Strong pairing if someone is willing to build Daniel’s look from scratch, since he does not have a guide here. Daniel wears a simpler, younger version of Sean’s casual aesthetic, and the age contrast between the two gives the duo an obvious visual dynamic. People who have played the game will get the brothers immediately. People who have not will see an older teenager and a younger kid, which is still a coherent pair.

Group Idea: Life is Strange 2 Cast

Sean Diaz, Daniel Diaz, Cassidy, Finn, Lyla Park

Might work, but every character here needs to be built from scratch since none of them have dedicated pages. Everyone in the group needs to know the game well enough to research and assemble their own look independently. Recognition outside the Life is Strange fanbase will be close to zero. This is a convention group, not a general Halloween party group.

Group Idea: Iconic Indie Game Protagonists

Sean Diaz, Claudette Morel, V, Ellie Williams, Lara Croft

Strong if the group is committed to a wide range of visual styles, and Ellie Williams and Lara Croft carry enough recognition to anchor the concept for most crowds. V from Cyberpunk 2077 reads as a futuristic punk, which is visually distinct. Sean in his hoodie and beanie will be the least immediately recognizable of the five, and someone will need to explain him to people who know the others.

Sean Diaz Halloween Costume DIY Tips

Building the Look

Most of this build is already in your closet. The three items worth buying specifically are the Wolf Squad hoodie, the beanie, and the backpack. Everything else can be thrifted or substituted easily.

Wolf Squad hoodie: buy it. Get the version with large chest text. Do not guess on the size of the print without zooming into the product photo.
Burgundy beanie: closet first. Any dark red knit beanie works.
Grey jeans: almost certainly in your closet already.
Brown belt: closet first. Let the strap hang slightly loose.
Brown suede jacket: thrift it. Worn-in is more accurate than new.
Military backpack: buy or thrift. Add patches if you have time. Skip them if you do not.
Brown high tops: closet or thrift. Any brown sneaker with some height at the ankle reads correctly.
Optional: add a black eyepatch for the Episode 4 look. One item, completely changes the read for anyone who knows the game.

Playing Sean at the Party

Sean’s mode is controlled, low-key anxiety. He is protective of people he cares about, occasionally funny, and genuinely trying to hold things together with limited resources. He talks to himself when things go sideways.

When someone asks who you are: you are traveling with your brother. You are heading south. You do not want to talk about Seattle.
“Dude… We are the wolves.” Works at any moment. No setup required. Say it with complete conviction.
“It’ll be fine. There’s nothing we can’t do… as long as we’re together.” Best delivered right before something at the party goes visibly wrong.
He narrates things to himself quietly, like he is writing in his sketchbook. If the party is loud and confusing, that mode is available to you.
If someone spots the eyepatch: “Episode 4.” That is the entire explanation. If they get it, they get it.

Sean Diaz Halloween Costume: FAQ

How do I dress like Sean Diaz for Halloween 2026?

The Wolf Squad hoodie is the base. Add the burgundy beanie, grey jeans, brown belt, and brown high top sneakers. Layer the brown suede jacket over the hoodie and strap on the military backpack. The hoodie and beanie together are what make the costume specific rather than just casual clothes.

Is the Sean Diaz Halloween costume still a good choice for Halloween 2026?

Life is Strange 2 has a loyal fanbase, but Sean’s look is close enough to regular teenage clothes that most people at a general party will not place it. At a gaming event or convention, recognition goes up significantly. The Wolf Squad text on the hoodie is the one thing that shifts the read from teenager to specific character.

What are Sean Diaz’s most famous quotes?

Two stand out. “It’ll be fine, Daniel. There’s nothing we can’t do… as long as we’re together.” Said at the start of the journey, before things get considerably worse. And the shorter one: “Dude… We are the wolves.” He says it at Mount Rainier National Park, alone in the woods with his little brother. He means it completely.

Who voices Sean Diaz in Life is Strange 2?

Sean is voiced by Gonzalo Martin, who improvised the nickname “enano” for Daniel, drawn from how he addressed his own younger foster brothers (Life is Strange Wiki). Life is Strange 2 was developed by Dontnod Entertainment and published by Square Enix.

What does the Wolf Squad hoodie represent in Life is Strange 2?

The wolf is Sean’s symbol throughout the game. The decision-consequence animation shows two wolves running together, one large and one small. Sean and Daniel refer to themselves as wolves and howl together during the journey. The hoodie is where that symbolism lives on a costume level, which is why it is the most important item in the build.

What happened to Sean’s eye in Life is Strange 2?

In Episode 3, an explosion at a cannabis farm scatters glass. A shard hits Sean’s left eye. He wakes up in a hospital in Episode 4, partially blind, wearing a bandage that later becomes a black eyepatch. If you want the Episode 4 look, adding a black eyepatch to the base costume gets you there with one item.

Does Sean Diaz have any powers in Life is Strange 2?

No. Sean is one of the only playable protagonists in the Life is Strange series without supernatural abilities. Daniel has the telekinesis. Sean’s job is to protect Daniel, manage the fallout of what Daniel does with it, and get them both to Puerto Lobos. He does this while being sixteen.
