Marvel Rivals Season 6.5 launched on February 13th with a new limited-time event called Citizenship of Monster Kingdom. The headline freebie is a Red Panda costume for Squirrel Girl — an Animal Party-themed skin you can unlock without spending any real money or premium currency.
Quick answer: Play matches during the Citizenship of Monster Kingdom event to earn XP, level up the free event pass track, and claim the Squirrel Girl Red Panda skin at no cost.

How the Citizenship of Monster Kingdom Event Pass Works
The event uses a battle pass-style progression system. Every match you play earns experience points that fill a progress bar, and reaching certain thresholds unlocks rewards across multiple pages. There are two tracks: a free track available to all players and a premium track that costs 690 Lattice. The Squirrel Girl Red Panda costume sits on the free track, so you never need to buy the premium pass to get it.
If you do purchase the premium pass, you gain permanent access to continue unlocking its rewards even after the event window closes. Free-track players should make sure to earn enough XP before the event ends, since the skin will only be available in the in-game Store for purchase afterward.

Steps to Earn the Red Panda Skin
Step 1: Log into Marvel Rivals after the Season 6.5 update. The Citizenship of Monster Kingdom event should appear in the events menu automatically.
Step 2: Queue into any match mode. Each completed match awards event XP that fills your pass progression, regardless of whether you win or lose.
Step 3: As you level up the free event pass, navigate to the rewards page and claim the Squirrel Girl Red Panda costume once you hit the required tier. The skin will appear in your Costumes inventory for Squirrel Girl immediately after claiming.

All Citizenship of Monster Kingdom Event Skins
Three new costumes arrive with this event, but only one is free. Here's the full breakdown:
| Skin | Hero | Track |
|---|---|---|
| Red Panda | Squirrel Girl | Free |
| Giant Panda | Rocket Raccoon | Premium (690 Lattice) |
| Duck Defender | Jeff the Land Shark | Premium (690 Lattice) |
The Rocket Raccoon Giant Panda skin dresses the character in a full panda suit, while Jeff the Land Shark gets a duck-themed look called Duck Defender. Both require the premium pass.

Other Free Rewards on the Event Pass
Beyond the Red Panda costume, the free track includes Animal Party-themed collectibles like emojis, sprays, and nameplates spread across multiple reward pages. Premium pass holders get additional exclusive cosmetics on top of those freebies. Once the event concludes, any rewards you didn't earn will eventually rotate into the in-game Store at standard pricing.
What Else Arrived with Season 6.5
The Citizenship of Monster Kingdom event is just one piece of the Season 6.5 content drop. Elsa Bloodstone joined the roster on February 13th as a new Duelist hero with monster-summoning abilities and a versatile weapon kit. Times Square also received a special Gambit and Rogue wedding parade celebration on February 14th, followed by Spring Festival activities featuring lion dance performances.
If you're a Squirrel Girl player, the Red Panda skin is one of the easiest freebies to pick up — just keep queuing matches and let the XP do the work before the event timer runs out.
