By the end, he has developed the inventions (flight suit, inferno blade) and the mindset necessary for HTTYD 2.

Initially revenge and power; later, family and acceptance.

Dagur begins as a crazed antagonist obsessed with killing Hiccup. Through the discovery that Heather is his sister, he finds a reason to love rather than hate. His arc is a slow, painful climb from madness to heroism, culminating in him sacrificing his ambition to save his family.

Viggo is Hiccup's dark reflection—a brilliant strategist who respects dragons only as resources. He dominates the middle seasons.
