Teacher Bun Bun (ぶんぶん先生 bun bun sensei, Bun Bun Teacher) is the final boss of Main-Chapter 3 in Battle Cats and sometimes appears in the Stories of Legend.
This is the strongest and most deadly enemy in the Empire of Cats chapters. It is first seen in Chapter 3-48, known as the Moon (Chapter 3-48) in the English version. Some Stories of Legend levels will also have Teacher Bun Bun and his colored variants. He has a massive 399,996 HP (that's nearly 1/2 of his castle) and 9,000 damage in Chapter 3 - Moon. People say he is impossible to defeat, but he can be defeated with the proper strategy, an example being a continuous "meatshield" spam (e.g Basic Cat,Tank Cat, or Boogie Cat).
Strategy
Strategies for first encounter:
Lineup: Macho Cat, Wall Cat, Sexy Legs Cat(Optional), Dragon Cat, True Valkyrie Cat, and an uber if you have one (Although it's not impossible without an uber).
Note: All your cats MUST be lvl 20 and you MUST have 100% treasures on Energy Drink, Giant Safe, Relativity Clock, Legendary Cat Sword and Shield on all chapters of Empire of Cats.
Lure the Kang Roo near the base
Once the Kang Roo is dead, start spamming your macho and wall cats. If you can, also spawn True Valkyrie.
Once you have enough money, start stacking Dragon Cats.
You should have 2-3 Valkyries at this point. Do not stop meatshielding and dragon stacking.
Once Bun Bun appears, meatshield in a way where Bun Bun won't hit both of your meatshields.
Bun Bun has 10 knockbacks, so count them to see how close he is to death.
Try the best you can to not make Bun Bun hit the dragon stack. Also spawn Valkyrie if she recharges
Do this until Bun Bun is dead. Once he is, good job! You have completed Empire of Cats, unlocked Bahamut Cat, got the catfruit storage, and are able to progress more in the game!
Summon a Valkryie Cat and use cats to protect her.
Upgrade your money to max, get full wallet.
If you are close to the enemy base, stop spamming cats
Once you have money, summon every strong cat you have.
When Teacher Bun Bun comes out, use every cat you have (you should have at least 4 meatshields).
Call God for knockback if Teacher Bun Bun is close to your range attackers.
You should win if you have good cats; Congratulations!
Note: only people which have these cats can do this strategy
Strategy for late game encounters
For now, you should have more anti-floating units in your team that can help you.Strong units like Catman,or stacks of heavy hitters like Dragon Cat or Paris Cat can deal enough damage to knock him back and prevent him from attacking your long-range units, or units with Slow/Freeze abilities can greatly help to win against him.Megidora is very helpful against him and his variants,his knockback ability can prevent him from getting close to your heavy hitters,and his slow ability can keep your line safe.Kai can also tank many hits from him (Specially in True Form),and deal heavy damage if she attacks him.
