Viper was a female SandWing dragonet with white-gold scales and a false Dragonet of Destiny who was the intended replacement for Sunny. Her unnamed parents and "uncle or something", as described by Sunny, were members of the Talons of Peace. She was chosen only because of her "convenience". She despised the NightWings, especially Morrowseer and Fatespeaker, wishing she could return home to her family at the Talons of Peace camp. She also harbored a deep dislike of the other false dragonets. Viper was the only false dragonet who died at the Night Kingdom while "battling" Starflight and the false dragonets during Morrowseer's "training": she fell into a river of lava after accidentally scarring Flame's face during a fight to kill Fatespeaker.
In the epilogue, they fly across the ocean with Morrowseer to the Night Kingdom and are placed in a cave. She tells Ochre that he smells bad, and she gets mad at Fatespeaker when the latter claims to be having another vision of the future.
Viper was introduced to Starflight, along with the rest of the false dragonets. She seems to like the idea of replacing Fatespeaker with Starflight, but still tries to kill him on Morrowseer's orders. She sticks with Squid during the chase, and both of them are chased back to their cave by four NightWing guards. As Flame and Ochre are in the dungeon, she and Squid have to spend the night in the NightWing Dormitory. The NightWing dragonets annoy her, and she threatens them with her tail before sulking in a corner.
The next day, Morrowseer takes them to a remote SkyWing outpost and orders them to convince the SkyWing soldiers inside to switch their allegiance from Burn to Blister. It was a failure, and they had to be rescued by NightWing soldiers. The soldiers then burned the outpost, killing the SkyWing soldiers in it. Later, she told Morrowseer that she would never do that again.
She is eager to jump into the practice fight with Fatespeaker. Viper blames Fatespeaker for her being taken to the NightWing island and nearly killed her before Starflight ran into her. She lost her balance, then her tail sliced into Flame's face, leaving him scarred, and she toppled into a river of lava by accident. Starflight had tried to get Ochre, the false MudWing dragonet, to save her using his fireproof scales, but Ochre either didn't have fireproof scales, didn't know he had them, or simply didn't care, and he didn't even try to rescue Viper. As he said, "I didn't even hatch on the Brightest Night; who knows if my egg was even red! I don't know if my scales are even fireproof, AND I AM CERTAINLY NOT JUMPING INTO A PIT OF LAVA TO FIND OUT!" Starflight then discovered that Morrowseer had been 'tinkering' with fate. When Viper didn't reappear above the surface, Fatespeaker wept by the river of lava for her lost "friend".
Sunny and Tsunami tell the Talons of Peace of Viper's death, including a SandWing who is hinted to be her uncle or another relative as he asks about her, but doesn't seem torn or upset when Sunny says that she is dead.
In the epilogue, Fatespeaker said that Viper was one of the dragons they cared about who had not survived the war.
Similar to the other false dragonets, she was very annoyed by Fatespeaker's imprecise predictions and found amusement in bullying Squid. She seemed to take pleasure in abusing Fatespeaker, nearly to the point of killing the NightWing and despised the NightWings for taking her away from her family. She acted aggressive to anyone she met, and usually kept to herself, but if anyone came too close, she'd threaten them with her tail to scare them away. In The Dark Secret, Starflight thought that Viper seemed like the exact opposite of Sunny.
"Send me in, too! I want a chance to bite her! I can definitely kill her, just give me a chance!" - To Morrowseer, requesting to fight Fatespeaker.
"This is your fault! I could be back at camp with my parents if it weren't for your stupid tribe!" -To Fatespeaker, about to kill her.
"Next time? I'm not stupid enough to go through that again."
"Fancy talk. Now let's see you actually do it."
"Wow, dragons actually call us that? Lame. I hereby forbid anyone to use that phrase again." -To the SkyWing group, when they called Starflight and the false dragonets 'The Dragonets of Destiny'.
- A viper is a venomous snake.
- Viper seems as though she hates every one of the False Dragonets of Destiny, but she doesn't really mind Flame.
- Viper was the dragon who accidentally gave Flame his scar.
- She is the second dragon to die by falling into lava, the first being Vengeance.
