They would be furious and determined to get Hiccup back. Tuffnut and Ruffnut would add their own unique brand of chaos to the rescue effort. They might come up with some out - of - the - box ideas to infiltrate Drago's hideout. The whole group would be united in their goal. They would also be very concerned about Hiccup's well - being, knowing how dangerous Drago can be. They would not rest until they had Hiccup safely back with them.
Hiccup's friends would be extremely worried. Astrid, being Hiccup's closest friend and love interest, would probably be the first to take action. She would gather the other riders and start planning a rescue mission right away. Snotlout might initially be a bit hesitant, but the thought of losing Hiccup would push him to join in. Fishlegs would use his knowledge of dragons to figure out where Drago might be hiding Hiccup.
One possible plot twist could be that Drago kidnaps Hiccup to use him as a bargaining chip against the dragons. Maybe he wants to force the dragons to submit to his will by threatening Hiccup's life. Another could be that Drago discovers some special power within Hiccup that he wants to harness for his own evil purposes. For example, Hiccup's ability to communicate with dragons might be something Drago wants to use to control all dragons.
Toothless is the most likely one. Their bond is so strong that Toothless would sense Hiccup's distress and come to his rescue. He could fly into Drago's hideout and cause chaos to free Hiccup.
Well, Hiccup is very resourceful. He could use the environment around him to his advantage. If he is locked in a place, he might find a weak spot in the structure, like a loose board or a hole in the wall. And he could call for Toothless secretly. Toothless, being highly intelligent, could find Hiccup and rescue him. Also, Hiccup could befriend some of Viggo's minions and convince them to help him escape.
In this kind of fanfiction, perhaps Hiccup would be in great danger. Drago might use Hiccup as a hostage to get something he wants, like controlling the dragons that are allied with Hiccup's people. He could also try to force Hiccup to reveal the secrets of his unique bond with Toothless.
Fishlegs would be really concerned and would use his knowledge to try and help. He might look for herbs or remedies that could aid in Hiccup's recovery. Snotlout, on the other hand, might initially try to act tough but deep down he'd be just as worried. He might try to show off his strength by helping to carry Hiccup or something like that. And Tuffnut and Ruffnut would be their usual chaotic selves, but also very caring towards Hiccup in their own unique way. They could make jokes to try and cheer him up while he's in pain.
Their friends are likely overjoyed at first. Fishlegs might be a bit of a nervous wreck, constantly worrying about Astrid's health and the well - being of the baby. He'd probably be reading every book he can find on dragon - rider pregnancies (if that's a thing in their world). Snotlout would probably make a bunch of inappropriate jokes at first, but deep down he's also excited. Ruffnut and Tuffnut would be their usual chaotic selves, but also show their support in their own unique ways, like bringing strange gifts they think the baby would like.
He might be shocked at first. After all, finding a baby out of the blue is not an everyday occurrence.
His relationship with Astrid might become more complicated. She might be initially shocked or even a bit scared of his half - dragon side. But as she gets to know that it doesn't change who Hiccup really is, they could grow closer. His dragon friends, on the other hand, might see him as more of an equal now that he has a dragon part in him.
In such fanfiction, Hiccup's upbringing by Drago often involves intense training and a challenging environment that shapes his character differently.
Stoick would be quite surprised and a bit worried. As a father, he'd take on the responsibility of caring for his baby son. He might be a bit clumsy at first, not used to dealing with a baby again. The other Vikings would have mixed reactions. Some might find it funny, while others would be more concerned about how to reverse the situation and get their leader back to normal.
