Zombified
From Worms Knowledge Base
Zombified is a worm state where the infected worm becomes lifeless and somewhat unpredictable. This state is caused by an enemy worm using a Life Remover on another worm. The zombified worm will appear as a more grey, blankly-staring worm with no expression whatsoever. They will also occasionally make ominous moaning sounds. Worms in this state have their control stripped away from the player, as if a CPU is taking the turn, in which it will blindly use a weapon which may or may not end successfully. Note that health loss of a zombified worm is reduced by 40%, making it harder to kill.
