(Continued after episode 26, Dragons Race To The Edge. May contain spoilers. READ AT YOUR OWN RISK.) Hiccup watched the horizon as a Dragon Trapper ship sailed away. Viggo and Ryker were long gone, the Dragon Eye in their possession. But what was worrying the gang was that Hiccup was not himself. Astrid was worried for him, the other Riders not seen how he reacted when Astrid told him he was long gone . . .

I guess the title explains it I don't own Httyd or any other movies mentioned (Requests are welcome)

Astrid knew she was different, and she had done for a while now. But what happens when she meets a boy named Hiccup and his Cyber-Dragon 2thless? Will her life change for better or for worse? And what evil lurks in the depths of Berk city, waiting for the perfect chance to strike?
