How to Throw an Avengers-Themed Birthday Party for Kids
Prices are accurate as of the time of writing and may have changed since — always double-check before buying.
Most of what's below is generic hero-themed party supply rather than official Marvel merchandise — only the tattoos and the favor boxes are licensed Avengers product, and we've said so where it applies. This guide is split into the four things you actually need to plan: how to decorate the room, what to dress guests in, what to have them do once they're there, and what to send home with them.
1. Decorating the Room
Start with the banner and backdrop set for instant color and a ready-made photo spot, then add the balloon arch if you want a bigger statement piece covering more of the wall.
The one to buy first if you're only buying one thing — a banner, a photo backdrop, a cake topper, 24 cupcake toppers, and balloons, covering both the wall and the dessert table in one purchase.
A red, yellow, green, blue, black, and silver balloon arch with two star-shaped foil accents — a bigger, more photo-ready statement piece than the balloons bundled into the banner set above. Glue dots, ribbon, and a decorative strip are included, so no extra tools needed.
10 comic-burst honeycomb pieces — "BOOM," "ZAP," "WOW," and more — plus 2 standing city-skyline decorations for the table. Peel the adhesive strip and unfold; no tools needed, and kids can help set them up.
Two 3-tier cardboard stands, each holding 18–22 cupcakes, printed with the same comic-city look as the centerpieces above. No tools to assemble, and having two on the table means dessert doesn't run out of room.
2. Dress-Up
Let guests suit up as soon as they arrive rather than saving it for later — a multi-cape set means several kids can get dressed at once instead of waiting on one costume.
8 capes with matching masks — Hulk, Captain America, and more — plus 8 slap-bracelet wristbands and a carry bag, enough for a full guest list to suit up as soon as they arrive rather than sharing one costume. Sized for ages 3–12.
Officially licensed Marvel tattoos of Captain America, Thor, Black Widow, Hulk, Nick Fury, and Iron Man, pre-cut into 70+ individual 2x2 inch pieces across 9 sheets — fast to hand out and apply without cutting anything yourself mid-party.
3. Activities & Games
Plan for a mix of active and calm — a toss game and a piñata cover the high-energy stretch, while the food trays are there for whenever the party settles into snacks or a movie.
Switches between bean bag toss, a kids' football target, a sticky-ball game, and darts, so one board covers several rounds without setting up a new game each time. Folds flat, with 4 ground stakes included for outdoor play.
Shaped like a number rather than a generic round piñata — this one is a 5, so it's worth double-checking that matches the birthday age before ordering. Includes the stick, blindfold, and confetti, so nothing else needs to be bought separately.
48 comic-print paper trays across four colors, sized for burgers, fries, or popcorn — a practical pick if the party winds down with a movie, since kids can hold snacks without balancing a plate.
4. Party Favors for Guests
One thing per guest that's genuinely worth taking home beats five throwaway trinkets. Both picks below are sized for a full guest list rather than needing to be topped up separately.
Reusable 16oz cups in four colors with matching lids, so kids can tell their own drink apart without asking. Sturdy enough to be reused after the party rather than a one-time paper cup.
Officially licensed Marvel favor boxes for 20 guests, each holding either 4 stickers, 4 temporary tattoos, or a self-inking stamper — pre-sorted per kid, so there's no last-minute assembling of individual goodie bags.
Sample 90-Minute Timeline
- 0–15 minGuests arrive and get their capes, masks, and wristbands on right away.
- 15–35 minBean bag toss — easy to run in rotating rounds while stragglers arrive.
- 35–50 minPiñata — the highest-energy moment, so save it for when everyone's already there.
- 50–65 minCake and singing.
- 65–80 minFree play or a movie clip, snacks served in the paper trays.
- 80–90 minFavor boxes handed out at pickup.
