Hijack

Hijack is the slash ship between Hiccup and Jack from the How to Train Your Dragon and Rise of the Guardians fandoms.

Canon
As the two are from different series, they have never met in canon. Even though they are both the main protagonists of DreamWorks film. Both have originate from books before their respective fantasy-advance films came out. They also have in common that both wanted to be noticed by people, as Jack wanted people to believe in him and Hiccup wanted to be accepted by his village. Both Hiccup and Jack have naturally brown hair, as Jack was confirmed to be brown-haired when he was alive. They have also flown through the air.

Fanon
Hijack is part of the  crossover fandom and its sub-fandoms. However, the ship started even before the RotBTD crossover existed, in the How to Train Your Guardian crossover. On AO3, it is the most written ship for Jack and the second for Hiccup, behind Hiccstrid. It is also one of the most popular crossover ships in all AO3, with +1400 works.

As Jack Frost originates from Nordic myths and Hiccup is a Viking, it is possible for Hiccup to believe in Jack. In addition, the large amount of snow in Berk could be due to Jack visiting the island frequently. This could lead to Hiccup meeting Jack, as Jack is a spirit and can only be seen by those who believe in him. Jack being an immortal while Hiccup is a mortal led to those who are fans of those kinds of ship to ship them.

As a main Big 4 pairing, it is common in many AU scenarios. When cast in roles, Hiccup is typically cast in the role of a female character, although this can vary depending on the AU and fan. One example is the Miraculous Ladybug AU, where Hiccup is cast as a male Ladybug and Jack is cast as Cat Noir. In a WALL-E AU, Hiccup takes the role of WALL-E and Jack takes the role of EVE. There have also been Monster/Vampire AU's that Hiccup as a vampire hunter who falls for a vampire (Jack) that he wouldn't bring himself to kill. This idea is due to them being featured as an immortal-mortal couple, along with Hiccup seeing the good in those who other have deemed as monsters and fans believe that it would help Jack to draw closer to Hiccup.

There have also been times when the ship has Jack as the Light Fury's rider or human trusting friend. Along with ROTBTD/ROTBTFMD fans creating fanon netizen versions of [https://marcos-jo.tumblr.com/post/612478951687847936 Jack and Hiccup from a DreamWorks website that resides within the digital, internet city world/universe from Disney's Ralph Breaks the Internet, whenever they feature either one of them with the netizen versions of Merida, Rapunzel, Elsa, Anna or Moana from Oh My Disney, since fans sometimes have the five female Disney characters in the modern style clothes for a Modern AU. While Hijack can simply have the two DreamWorks characters as friends of five Disney, netizen characters, so they can feature the romantic or friendship side of the DreamWorks crossover ship in a Wreck-It Ralph/Ralph Breaks the Internet AU].
