Cobra is the common name of various venomous snakes, most of which belong to the Genus Naja.
Final Destination: Destination Zero
When Jane Stanley, Hector Barnes, and Andrew Caine meet at Jane's house shortly after retrieving a sarcophagus that appeared a few days after the explosion at Madame Adrianne's house, Jane asks her butlers, Fitch and Jensen, to give her some time alone in her room. Hector and Andrew open the sarcophagus with a crowbar.
Hector reaches out and begins to stroke the mummy's eye sockets before screaming as a cobra latches onto his arm and coils around it, biting him, and he dies from the venom.
As Andrew watches Hector die, Jane tries in vain to leave the room until another cobra bites her tongue. Andrew panics even more as his friends die. He backs up to the wall, twists his arm, and grabs a stick to defend himself against the cobra, trying to strike it on the head, but misses. The cobra twists its head back and spits venom into Andrew's eyes from five feet away, blinding him. Andrew clutches his head as he screams and falls to the ground in agony, while swarms of cobras slither toward him and bite his ankle, arm, neck, and groin, injecting venom throughout his body and killing him.
Given that it was the Cobras who killed the Egyptologists instead of Death, the reptiles could be considered Death's Servants.
