The Dragonbite Viper is a deadly species of venomous snake that mostly dwells in the Kingdom of Sand. It is the only serpent that is able to kill a dragon in one bite. It is only known to live in the continent of
Dragonbite vipers are first mentioned in the Scorpion Den, where it was said one had been spotted near an orphanage, although it was a false story made up by Addax to distract Thorn. Qibli explained to Sunny what it was shortly before she was kidnapped and taken to Burn's stronghold.
The viper was first seen when Burn opened the box Blister sent to her when the three sisters met outside of Burn's stronghold. She recognized the hissing and killed the snake easily. However, Blister had sent a second snake as well, which sprang out and bit Burn's ankle, killing her. The dragonbite viper then tried to attack Sunny, but Clay pushed her and the rest of the dragonets out of the way and got bitten instead; however, he was saved by Peril, who burned out the venom before it could spread to his heart. Peril then killed the serpent by stepping on it and burning it.
Dragonbite vipers are one of the most feared animals in Pyrrhia because as their name implies, they are the only known snake that can kill a dragon with one bite. This was proven at the end of The Brightest Night, where a bite to the foot from one killed Burn in a matter of minutes.
A dragonbite viper's bite turns black and is at first the pattern of a starburst, and can be seen spreading through a victim's body. When it comes in contact with dragon flesh, the dragon is seized with spasms, convulsions, and terrible agony.
- It is possible that dragonbite vipers are much more aggressive than normal snakes.
- Dragonbite vipers are rare, according to Starflight.
- The poison can be burned out of a dragons body, and provided that the wound is far away from the heart, the dragon's odds of surviving seem decent. An example of this was when Clay was bitten on the leg and Peril used her firescales to save him.
- Dragonbite vipers have been confirmed to live in the Kingdom of Sand so far, and may or may not live anywhere else in Pyrrhia.
