  • Cost: $$$$$ Here's a rough breakdown:
      • Basic (from your wardrobe or thrifted): ~$10-$30 (if you need to purchase a robe or belly prosthetic).
      • Mid-range (mix of new and pre-owned items): ~$30-$75 (if you need to purchase new elements like a wig, specific robe color, or a belly prosthetic).

Fat Thor Cosplay

Transforming into Fat Thor isn't just about the clothes; it's about capturing his downtrodden spirit and surprising flashes of his former heroism. Let's explore some key mannerisms that will make your Fat Thor costume truly come alive.

How to act like Fat Thor at the Halloween Party:

A Posture of Defeat

  • What To Do: Fat Thor carries the weight of his failures in his slumped posture. It's about a sense of resignation and loss.

  • How To Do It:

    • Shoulders Down: Roll your shoulders forward and down, letting them slump inward.
    • Head Tilt: Allow your head to subtly tilt slightly forward.
    • Slow and Heavy: Your movements should feel slower, slightly labored. Let your energy feel low.
  • Bonus Tips:

    • Capture the Emotion: Think back to scenes in Endgame where Thor is lost in self-doubt. Try to channel that inner turmoil.
    • Practice Makes Perfect: Use a mirror to observe your posture and make adjustments.

Mumbled Musings

  • What To Do: Thor's dialogue is often mumbled, halfhearted, and infused with a bit of dark humor.

  • How To Do It:

    • Low Volume: Speak quietly, almost as if talking to yourself.
    • Slurred Words: Don't be afraid to let your words run together slightly.
    • Sarcasm and Apathy: Infuse your lines with a sense of both bitter humor and "I don't really care" detachment.
  • Bonus Tips:

    • Rewatch Key Scenes: Pay close attention to Thor's dialogue delivery when bantering with the other Avengers.
    • It's All About Attitude: Focus on that underlying sense of self-loathing and cynicism to truly nail his vocal style.

Food and Gaming Obsession

  • What To Do: Fat Thor retreats into comfort-seeking behaviors – nonstop snacking and obsessive gaming.

  • How To Do It:

    • Prop Power: Carry around a bag of chips, a can of soda, or any "gamer" food that fits the vibe.
    • Focused Distraction: Pretend to be completely engrossed in a handheld game or stare blankly at a screen (your phone will do!).
    • Periodic Bites and Sips: Mimic eating and drinking from your props to sell the effect.
  • Bonus Tips:

    • The Messier, the Better: A few crumbs on your Fat Thor costume will add to the realism.
    • Character References: Remember Thor's obsession with Fortnite and his nickname "Noobmaster69".

Flashes of the Hero Within

  • What To Do: Despite his appearance, Thor is still a hero. Brief moments of his old self shine through.

  • How To Do It:

    • Momentary Straightening: When Thor feels protective or determined, let your posture straighten slightly.
    • Focused Gaze: Fix your eyes into a steely, determined stare for just a few seconds.
    • A Hint of the Old Voice: Let a single line or phrase be delivered with Thor's usual heroic tone.
  • Bonus Tips

    • Subtlety is Key: These moments should be brief and surprising, not a complete change of character.
    • Know Your Triggers: Think about moments where Fat Thor's protective nature towards his friends flickers through.

By combining these mannerisms, you'll bring a deeper dimension to your Fat Thor costume. Remember, it's about capturing the contrast between his outer apathy and the lingering heroic spirit within.

Couple, Group, and Family Costume Ideas

Dive into a universe of creativity and fun with costumes that complement the unforgettable Fat Thor. Whether for couples, a group, or the whole family, there's a wealth of characters to choose from for an ensemble that’s both heroic and humorous.

Couple Costume Ideas

Idea 1: Fat Thor and Valkyrie

  • Fat Thor's trusted ally, Valkyrie, makes a striking counterpart. Their dynamic represents a powerful camaraderie and mutual respect, tinged with humor. This pairing is my personal favorite for its depth and contrast.

Idea 2: Fat Thor and Loki

  • Consider the classic brotherly duo of Fat Thor and Loki. The juxtaposition of Fat Thor's disheveled look against Loki's typically sharp appearance makes for a compelling and entertaining couple's costume.

Idea 3: Fat Thor and Star-Lord

  • For a cross-title pairing, why not match Fat Thor with Star-Lord? Both characters bring a mix of heroism and flawed humanity, complementing each other's journey of self-discovery and redemption.

Group Costume Ideas

Idea 1: The Avengers Ensemble

  • Gather your squad and assemble an Avengers team that includes Iron Man, Ant Man, Wasp, Hulk, Captain America, Hawkeye, Quicksilver, Scarlet Witch, and of course Fat Thor. Representing various heroes from the franchise, this group costume allows everyone to shine and is perfect for a moderate-level costume challenge.

Idea 2: Asgardians of the Galaxy

  • Create a theme-based group of 'Asgardians of the Galaxy,' with Fat Thor leading the way. It’s an excellent opportunity for a crossover ensemble that is fun and easy to coordinate.

Idea 3: The New Asgard

  • For a unique twist, form a group representing the inhabitants of New Asgard. It's a nod to Fat Thor's leadership in his more grounded, human-like state and offers a range of easy-to-assemble looks.

Family Costume Ideas

Idea 1: Thor's Asgardian Family

  • Thor's family offers rich costume possibilities, from Odin to Hela, and you can even include Loki. This family costume theme caters to all ages, with each member representing Asgardian royalty in their unique style.

Idea 2: Heroes of Midgard

  • For families, opt for a 'Heroes of Midgard' theme, where each member dresses as different earth-based heroes, with Fat Thor as the centerpiece. This theme offers flexibility and can range from easy to challenging based on the costumes chosen.

Idea 3: Chris Hemsworth Characters

  • For a group willing to dive deep into filmography, dressing as characters played by Chris Hemsworth, such as Agent H from "Men in Black" or Tyler Rake from "Extraction," with someone as Fat Thor, can offer a fun and varied ensemble. This is more challenging due to the variety of costumes but can be a real hit.

Throughout the years, I've seen and been a part of many themed costume groups. The key is in the planning and the joy of embodying characters together. As an experienced costume designer, I recommend discussing and choosing a theme that excites everyone involved. Remember, the aim is to have fun and create lasting memories, all while ensuring inclusivity and comfort for all participants.
