While enraged, King Fleshpound can damage other zeds when charging, so they will attempt to get out of his way.
Alternatively, he will calm down after not seeing a player for 30 seconds. Rage will end once King Fleshpound successfully lands a hit on a player, or he is hit with an EMP Grenade. When rage begins, he will pound the floor a few times and then begin charging at players. Like a regular Fleshpound, he also has an enrage mechanic after sustaining a certain amount of damage, which will change his chest core from yellow to red. He also lacks their weakness to explosives, and has more resistances overall. In addition to being a larger, more powerful Fleshpound, he is also equipped with a powerful laser and a shield he can activate when low on health.
Initially he was just the boss of the Weekly Outbreak 'Poundemonium' but soon became a full-fledged boss in Survival Mode as well. 1,843 (Hell on Earth) King Fleshpound was the third boss enemy added to Killing Floor 2.
