He has a much higher attack and more health than Teacher Bear and attacks more frequently along with a 100% chance to knockback cat units. However, he also has 10 knockbacks just like the original Teacher Bear, making him easier to control. Treat him like a non-Zombie version of Cadaver Bear, but with more knockbacks.
Strategy
Use powerful, long ranged Area Attack cats like Bahamut Cat,Cyborg Cat or Luxury Bath Cat. His knockback ability is not much of a problem, in fact, it can save some of your cats from taking unnecessary damage by blocking them from other enemies' attacks, so knockback immunetankers may not be the best idea.
