"Not a SINGLE Night Fury. Only different forms of it." Snotlout complained. "Why did I have to go there again?"
"Because you volunteered doofus." Tuffnut replied casually. "Hiccup would have loved to go, but he had to supervise the building of the underground training facility."
"That emerald fury could have killed me!" Snotlout complained again. "I was lucky I shot it out of the sky. It had incredible speed, it caught up to me faster then Toothless ever has! After it closed in on me something amazing happened. It did all sorts of acrobatic tricks. Like loop de loops and spirals. I caught a few glances at it. It had four spines on its tail instead of two. In fact, I could barely make out two of them. They whipped with the wind at incredible speed. I just guessed where to shoot and nailed it on its left wing!"
"Snotlout being successful at something?" Ruffnut asked Tuffnut. "That's never truly happened before."
"Ha ha guys." Snotlout said. "You guys are just jealous that I slayed one of the most powerful species of dragon in history!"
Tuffnut squints his eyes and reaches for something. He whipped out his chicken.
"The chicken does not believe your tale!" He translated.
"I don't care what the chicken thinks!" Snotlout shouted back.
"You do realize that Tuff doesn't actually speak chicken." Hiccup said pointlessly.
Snotlout ignored him. "I am going to bring back a Fury's head just to show you all!"
Suddenly the Emerald Fury burst through the door. It's blue eyes showed no emotion. Without warning the fury backflipped and clung to the ceiling with its claws. It shot four blasts at snotlout who deflected them with his iron shield. Toothless charged out from behind Hiccup to fight the Fury.
"Hello Brother." The Fury Telepathically spoke to Toothless. "How long have you been captive?" Toothless just stood there confused.
"Toothless, Plasma Blast!" Hiccup ordered.
The ball of purple plasma knocked the fury through the roof and onto its back.
"For many years we thought the night clan had gone extinct. You prove that assumption wrong. You could have had a home on the Fury Isle. But now you chose combat. Prepare for death."
The fury's claws grew longer and little spikes erupted out of the scales. Its blue gaze turned blood red and its wings shortened and became more jagged along the edges. The fury pounced on Toothless and pinned him to the ground.
"Toothless!" Hiccup shouted in panic. "Stay calm, I got this!"
Hiccup pulled out a small cylinder and pressed a few buttons. It began bellowing out large amounts of zipple back gas onto the fury. Hiccup pressed another button and ignited all the gas creating an enormous explosion.
Toothless staggered to his feet. The fury still stood several meters away unharmed. The fury caught a green fire and disappeared from view. The fire stayed in one place but the fury seemed to have disappeared. A figure walked out of the flames. It was a figure made out of emerald. It seemed that it could be the dragon.
"Human worms." The figure said. "You are powerful, but you have never encountered a true Dragon Fury. That Night Fury knows nothing about what it is or its capabilities. I shall give you a simple taste of dragon fury."
The figure shot up into the air. A disturbing scream filled the air as the green streak of light flew into the air.
"Behold, death by unholy lightning!"
The figure exploded and the fury shot off into the night. The sky turned green and it was as bright as day. Lightning struck a nearby rock and obliterated it. Then hundreds more followed. Bolt after bolt explosion after explosion. The island shook for several hours.
The next morning they gang emerged from the underground training facility. Everything had either burned to the ground or was damaged greatly. Hiccup looked up and saw the sky. The world was full of smoke. In bright green letters sitting in the sky the words spelled a threatening message.
You're playing a dangerous game. That was your warning, unholy lightning is not the worst we can do. Bring us the Night Fury. Unless you want to be destroyed.
