Hiccup Horrendous Haddock III. 

Hiccup was once the runt and outcast of Berk…that was until he met Toothless and changed how Berk thought about Dragons and created the Dragon Riders and Dragon Riding School.

 Verses 

Berk: CANON.

Descendants (Isle): When Hiccup refused to allow the magic and the dragons to be removed from Berk by the King. Hiccup was banished to the Isle of the Lost as punishment along with his young daughter. Splitting them from his wife and son.

Now, the both of them try and keep their territory safe, and the rumours about their hero status on the down low.

Descendants (Auradon): Berk was pulled into Auradon when Fairy Godmother created the United States of Auradon, and so Hiccup and the Berkians learned how to integrate themselves into the new ways of thinking. Hiccup soon became a teacher in Auradon Prep with Toothless as his teaching assistant.
