- "Change is the way of all things. And with change comes devastation-- And with devastation, opportunity. Growth. Evolution. Those great, dreaming dragons knew this."
- ―Calder's last line
Calder is the main antagonist in the Graphic Novel, The Serpent's Heir.
Attempting to Evolve
In the beginning of The Serpent's Heir, Calder travels to Berk, acting as an ambassador or emissary for Nepenthe. He asks to speak with Stoick the Vast to beseech help for his People, not knowing that Stoick was recently deceased. He appears fairly unafraid of Berk's Dragon's which is somewhat unusual. Calder addresses Hiccup as Berk's Chief instead, asking for him to come to Nepenthe to investigate the frequent tremors and bodiless dragon growls there.
The Dragon Riders arrive at Nepenthe and are unable to find the source of the tremors. At a final meal, Calder poisons most of the Dragons and the Dragon Riders. Calder imprisons them and seeks to take Toothless' wings to complete his personal "transformation" into a dragon. Calder believes he was meant to be a dragon and believes the tremors are a sign for his "transformation".
Despite the destruction of his land and people, Calder continues to harass Hiccup in his pursuit of transformation. He has taken and wields Hiccup's Inferno blade. Hiccup throws a canister of Zippleback gas at the blade, exploding on Calder. Calder falls off a cliff in a blaze of fire.
Calder is a troubled person who believes beyond reason that he was meant to be a dragon and not human. He feels he must "evolve". His desire blinds him to the dangers to himself and his people, and feels justified in using devious means to achieve his "Evolution".
Calder has blonde hair and blue eyes, and what appears to be dark eyebrows. He wears a long cloak to hide his extensive tattoos. The tattoos are to make him look like a dragon, and are green scale designs with stylized wings on his shoulders.

- "I am Calder of Nepenthe. My king, Mikkel the Munificent, has sent me here on a matter of grave import."
- "The fate of our entire island is at stake. Please, you must tell me where is Stoick the Vast?"
- "Alas, change is the way of all things. But legacies endure."
- "But you'll find our king in not like other leaders. He prefers a more natural setting from which to rule."
- "We didn't "do" anything. But I see some of you took King Mikkel's suggestion to visit our hot pools."
- "End me? Why would your dragons end me -- when I am becoming one of them? Lower your weapons and submit to my glory so that you and your dragons might live long enough to witness my transformation."
- "I have shed my old skin, Chief Hiccup. What do you think of my true form? Do you know I have always understood that I was different... even as a boy? Since birth, I've been a dark, coiled dragon trapped in the weak flesh of a man. But that's about to change for me--the son of a dragon. The Serpent's Heir."
- "My followers didn't believe either, not at first. But these quickening tremors are confirmation from the gods. Thanks to you, I now have the gift of fire. And thanks to your Night Fury, I will shortly have real wings, not this wooden--"
