Cadaver Bear is a Zombie variant of Teacher Bear. It burrows under cats, moves significantly faster, gets knocked back only four times and attacks non-stop like Assassin Bear, allowing it to push much more easily than Teacher Bear. Unlike most other Zombies, it revives with 100% HP instead of 50%.
It's recommended to stall this enemy with tons of preferably strong meatshields. DO NOT USE ANY ATTACKERS WITH UNDER 360 RANGE (only exceptions are Long Distance units, but they only help if there are peons to use as stepping stones), as they will be killed nearly instantly by its non-stop attack rate. Therefore, the only anti-ZombieRare Cats that can outrange this monster are Corrupted Psychocat and Cataur (365 and 390 respectively), with Target Zombietalents. Although Corruputed Psychocat has been well-known to be a reliable support unit, he mostly fails to slow down Cadaver Bear due to his speed and short range differences. Cataur, however, can be a very potent attacker, especially with the Zombie Killer Talent unlocked.
All Uber Rares from the Iron Legion event are exceptional counters to this enemy, as long as they're protected by meatshields. As much as possible, DO NOT LET IT REVIVE UNDER ANY CIRCUMSTANCES. Best case scenario, he revives at his base. Worst case scenario, it revives in front of your attackers and quickly demolishes them.
100% chance to burrow underground for 1,125 after a Cat enters its range (1 time); 100% chance to revive at 100% HP after being dead for 360f 12 seconds (1 time).
*In each stage, there is strength magnification, the value of health and attack power varies because of this.
Cadaver Bear's appearance and description may be a reference to the stereotypical depiction of Frankenstein's Monster, an unnamed entity forged from dissected corpse fragments whose most popular appearance has bolts in his ears.
