So, you want Courier Cat. Honestly, if you’re playing The Battle Cats right now, you basically have to get him. He’s not just "good." He’s fundamentally broken. He changed the meta so hard that PONOS had to start designing stages specifically to counter him. If you don't have this red-destroying delivery bird yet, you're essentially playing the game on hard mode for no reason.
But here’s the thing. Most people think you just "get" him like a gacha pull. Nope. Courier is a Behemoth Slayer, and the path to unlocking him is tied to a specific grind that confuses a lot of players because the UI in The Battle Cats can be a bit... cryptic.
How to actually unlock Courier Cat
First off, let’s clear up the requirements. You aren't looking for a single drop. You're looking for Behemoth Stones. Specifically, you need 5 Red Behemoth Stones and 5 Purple Behemoth Stones. You also need to have cleared the "Enigma" stage called Hunter’s Map I.
Wait. It’s actually simpler than that, but also more annoying.
To even see the option to craft Courier in the Cat Storage (Evolution) menu, you have to complete a set of missions. These are the "Behemoth Culling" missions. Specifically, you need to clear stages in the Gapra Jungle. Once you've cleared enough of these, you’ll trigger the mission reward that hands over the Ancient Egg: N001.
That egg is Courier. Well, it’s the shell of Courier.

The Egg Evolution Problem
Once you have Ancient Egg: N001, it sits in your Special Cats list looking completely useless. It has zero attack. It just sits there. To turn it into Courier Cat, you need those stones I mentioned. You go to the Evolve screen, spend the stones, and boom—suddenly you have a Long Distance (LD) area attack beast that deletes Red enemies and hits like a freight train against Behemoths.
It’s a weird progression. Most units you just level up to 10 or 30. For Courier, the "True Form" (which is actually just its second form) is the only reason the unit exists.
Why everyone is obsessed with this unit
It’s the stats. It’s always the stats. Courier has a massive massive damage ability against Red enemies. But that's not why he's top-tier. Lots of cats have massive damage.
It’s the Blindspot.
Courier is a Long Distance attacker. He hits enemies between 150 and 350 range. Because he’s so fast—speed 26—he rushes into position, throws his package, and clears the field. His fast attack frequency means he creates a "dead zone" for Red enemies. He effectively replaced Paris (Cyborg) Cat for a huge chunk of the mid-game because he’s cheaper to spawn and has way higher survivability against the enemies he’s meant to fight.

I’ve seen players struggle with Stages like Manic Dark Cat or Hannya for months. Then they get Courier. They win in three minutes. It’s that dramatic.
The Behemoth Slayer Trait
Beyond just being a Red-killer, he has the Behemoth Slayer ability. In 2026, The Battle Cats is littered with Behemoth enemies like Wild Doge and Casaurian Ahirjo. These guys have ridiculous health pools. Courier deals 2.5x damage to them and takes only 0.6x damage from them.
He’s a specialist that accidentally became a generalist. Even on stages without Red enemies, his raw DPS is often higher than your standard attackers.
The Grind: Hunting for Stones
This is where most people quit. They see they need Purple Stones and they go "where?"
You have to farm the Hunter’s Maps. These appear in the Legend Stages/Event Stages area.
- Gapra Jungle: Best for Red/Yellow stones.
- Ashibi Desert: Best for Blue/Green stones.
- Takobe Gully: Best for Purple/Yellow stones.
The drop rates aren't 100%. Sometimes you run a stage and get nothing but a "clear" and some XP. It’s frustrating. But you need to check the "Event Data" or your local time-zone trackers to see when these stages are active. They aren't always there.
A Quick Tip on Stone Priority
Don't waste your Purple stones on the other early eggs unless you've already finished Courier. Honestly. Egg N003 (Gaslowe) or N004 have their uses, but they aren't game-changers like N001. Courier is the priority. Period.
Common Mistakes When Trying to Get Courier
- Ignoring the Missions: You can farm 100 stones, but if you haven't claimed the reward for "Clear Gapra Jungle 1" in the Mission Tab, you won't get the egg. Check your missions. Seriously.
- Thinking Level Matters: You don't need to get the egg to Level 10 to evolve it. You just need the materials.
- Underestimating Stage Difficulty: Gapra Jungle 1 is easy. Gapra Jungle 3+ starts introducing enemies like Casaurian Ahirjo (the duck). If you don't have a good meatshield line, that duck will shred you before you can even farm the stones to get the cat that kills the duck. It’s a bit of a Catch-22.
How to use him once you have him
You don't just spam Courier. Well, actually, you kind of do.
But you need to protect his blindspot. Since he can't hit anything closer than 150 range, if a fast enemy like a Ginger Snache gets inside his personal space, Courier is useless. Pair him with something that has a small hit area or knockback.

The Math of Courier
Let's talk numbers for a second. At level 30, Courier has about 12,000 HP and does roughly 3,800 damage per hit. Against Reds, that damage jumps to nearly 15,000 per hit because of the Massive Damage multiplier (assuming you have all the treasures).
If you're at the end-game and have him at level 50? We're talking 24,000 damage per hit against Reds. For a unit that costs 600 cents, that is statistically insane.
Actionable Next Steps to Get Courier Right Now
If you’re staring at your screen wondering what to do first, follow this exact path:
- Check your Missions: Look for the "Behemoth Culling" section. See if you've cleared Gapra Jungle 1. If not, go to the Legend Stages and find it.
- Clear Gapra Jungle Area 1-5: This will guarantee you the Ancient Egg: N001.
- Wait for Hunter’s Map: You need those Purple Stones. Takobe Gully is your best bet, but you can also get them from "Behemoth Stones" stages that pop up during specific event windows.
- Farm the XP: You’ll need a decent amount of XP to get him to level 30 once he's evolved. Don't spend it all on gacha units you aren't using.
- Equip and Win: Once you evolve him, put him in your general loadout. He replaces your mid-range attacker immediately.
Courier Cat isn't just a trophy. He's a tool that unlocks the rest of the game. Without him, Behemoth stages are a nightmare of attrition. With him, they become a farmable resource. Get the egg, get the stones, and stop making the game harder than it needs to be.
