- "EVIL BALLS!"
- — Nero when he spots an Insanity Elemental.
Insanity Elementals, also referred to as Meatballs by Jack Vincent and Jessica Rose, as well as in Dead Ops Arcade 2: Cyber's Avengening, are an enemy in Call of Duty: Black Ops III on the Zombies maps Shadows of Evil and Dead Ops Arcade 2: Cyber's Avengening, as well as appearing throughout the Nightmares mode. They hunt down players, and when contact is made they explode, injuring the player, similar to R.A.P.S. in multiplayer mode. They are made of twisted flesh with multiple glowing mouths, screaming as they roll. In Shadows of Evil, they appear along with Parasites after the second parasite round, similar to the Hellhound rounds, including the Max Ammo power-up being dropped once the last one is killed.
Insanity Elementals spawn into the map by falling from the sky as glowing orbs. If playing coop, they will target certain players, instead of the player near their spawn location.
They also appear prominently in the Easter Egg, during the "capture the flag" round, where they will continue to spawn until the flag has been charged and taken to the ritual site, forcing the player to protect the flag from being destroyed by them and the Shadow Man.
The Nightmares versions act basically the same as the ones in Shadows of Evil. They will also appear if a player uses a Mounted Turret for too long and it will instantly kill the player if not destroyed; they will continue to chase the targeted player even after dismounting the turret.
The Dead Ops Arcade 2: Cyber's Avengening versions act mostly the same, but now when one is damaged enough it will explode into several smaller ones.
