To mark a decade of quirky feline warfare, The Battle Cats by PONOS is teaming up with none other than Sonic the Hedgehog for a wild, nostalgic celebration. Over 100 million players have experienced the chaos of these fluffy fighters, and now, they’re diving headfirst into the world of Sonic from August 4 to August 18, 2025.

This special event unleashes fan-favorite Sonic locations, iconic characters, and exclusive rewards for a limited time only. Whether you’re a long-time Sonic fan or a Battle Cats veteran, there’s plenty to scratch that collector’s itch.

From Green Hill Zone to the Catclaw Dojo

The crossover delivers five exciting new maps inspired by Sonic classics. You'll venture through:

• Green Hill Zone,
• Chemical Plant Zone, and
• Sky Sanctuary,

…all available via Legend Stages, each packed with five limited-time stages. Expect high-powered Sonic enemies, fast-paced battles, and wild surprises.

Next, test your skills in the Radical Highway Gauntlet, which includes 20 demanding stages. Complete them all to earn major in-game rewards!

And don’t miss the Arena of Honor in the Catclaw Dojo, where you can compete globally by racking up high scores. Think you’re the fastest cat on the leaderboard?

Plus, simply logging in during the event rewards you daily with in-game items — and on Day 5, you’ll unlock the exclusive Tails Cat unit for free!

New Feline Recruits: Sonic, Tails, Knuckles, and Shadow

Take your chances in the Sonic Collab Capsule machine to summon powerful new units:

• Sonic, who evolves into Sonic & Cat
• Tails, evolving into Tails & Cat
• Knuckles, who becomes Knuckles & Cat

Each of these Uber Rare units brings their signature moves and style — now enhanced with feline flair.

But it doesn't stop there! You’ll also find Rare Units like:

…and the fan-favorite Tails Cat, available as a login stamp reward, which also evolves into Tails Cat CC!
