The Fleshpound is the most powerful specimen outside of the Bosses and appears in all Killing Floor games. It has spiked gauntlets mounted on it's arms that spin and shred whatever they come in contact with.
The most notable mechanic with the Fleshpound is that it will enrage after sustaining a certain amount of damage. When enraged, the light in it's chest changes from yellow to red. On Suicidal Difficulty there is a 20% chance for it to spawn already enraged, and a 33% chance on Hell on Earth.
While enraged, they cannot dodge to avoid grenades. Rage will end once it successfully lands a hit on a player, or they are hit with an EMP Grenade. Alternatively, it will calm down after not seeing a player for 30 seconds.
Enraged Fleshpounds can damage other zeds when charging, so they will attempt to get out of it's way.
While not enraged, Fleshpounds in Killing Floor 2 possess the ability to block, reducing all damage taken by 10%. Attacks to their gauntlets always deal 80% less damage.
The glowing core on their chest also serves as a weakpoint, taking 10% extra damage from all attacks.
After being decapitated, Fleshpounds take 7 seconds to bleed out, instead of the standard 5.
Killing Floor 2 introduced the Quarter Pound (a weaker variant that can spawn as a pair in place of a standard Fleshpound), and the King Fleshpound (a Boss enemy).
A Fleshpound also serves as the final boss of the Catacombs stage in Killing Floor: Incursion.
