Li'l Bun Bun was also present as a regular enemy, and would appear every now and then to create a barricade from attacking the enemy ships if defeated, he would drop a plethora of rewards. They would constantly shoot large plasma balls from their mouths or their fists. In Nyanko Defence Force, Teacher Bun Bun and Relic Bun-Bun had several new variants that could be fought as bosses or Raid Bosses. Teacher Bun Bun was the main antagonist of Nyanko Daibōsō, where he would periodically appear in front of the player's cat for a few seconds and drop coins every time he took damage. *Note that these are Teacher Bun Bun's stats at 100% strength magnification he does not appear at magnifications under 400% in any stage.

Later in the game, Teacher Bun Bun and most of his variants' pushing power decreases drastically despite their bulk and brute strength, due to the player having faster meatshields, like Crazed Cat and Crazed Tank Cat, and powerful anti-floating True Forms such as Sanzo Cat and Cameraman Cat to cripple them.

Even so, he is beatable without their assistance.

Anti-Floating units with slow or freeze abilities like Delinquent Cat and Kotatsu Cat are quite helpful, provided they have enough range to land a hit on him.

Take advantage of his short reach and prioritize long-ranged attackers over tanks Mythical Titan Cat can only take so many hits from him, but a gang of Dragon Cats and Paris Cats can deal massive damage given enough time at a range advantage.It is highly recommended if not required to get all Superior Treasures in all Empire of Cats Chapters (prioritize the Energy Drink, Giant Safe, Relativity Clock, Super Register, Legendary Cat Shield, and Legendary Cat Sword) to make him manageable, along with upgrading every cat you're using to level 20.He may seem an impenetrable opponent, but he can be defeated with the proper strategy, an example being Sexy Legs Cats and Dragon Cats stacked in tandem with a continuous spam of ' meatshields' (e.g., Macho Cat, Wall Cat, Coin Cat, Catburger, Samba Cat, etc) to delay and absorb his hits. He can and will destroy anything that enters his range (200) - that includes UFO Cat, Whale Cat and Mythical Titan Cat. Teacher Bun Bun is by far the toughest opponent faced in Empire of Cats, with much higher health and pushing power than any previously encountered enemy due to his rapid, short-ranged area attacks and high speed.
