From the "Random Blurbs" section in the "" file in the decompression Axiom. This is what happens when a bored coder with no storytelling experience decides to write something relating to his favorite movie and a most recently played game.

Though Hiccup had the power of the Wild Card, there wasn't a single Persona he enjoyed using more than his Toothless. His Night Fury. His friend. Despite being just a facet of his overactive imagination, this fragment seemed to him to be the most real out of them all. This fragment of his own personality... a fragment of his own? It seems to him to be a fragment of someone else's personality. Something much older than he was. Ancient, perhaps. Not his. No, it couldn't possibly be his, and yet it was. It was his Persona. One that really didn't fit in. Like himself.

Every day, he waited. Waited for that dreaded Dark Hour. Not that there was anything wrong with it, except that it was the hidden 25th hour of the day, but it was then, all alone in his room, he could without any strange stares from his teammates, summon his Persona. His personal friend. His Night Fury. Every Dark Hour he wasn't shifting around in Tartarus, he would be there, in his room, basking in the presence of his personal guardian. The one who saved his life many times. It was like a heaven amidst an ever-present Green Death that permeated that Hour. It is as it should be, with his friend.

Hiccup never really knew Orpheus. Toothless was his first, and he'll never get rid of him like he did so many times with his other Personae. Pixie? Toothless had that one for lunch many months ago. Inugami? Got rid of him as soon as something else came up. Odin? Didn't get along well with Toothless so he discarded him rather quickly. Helel? Tempting, but only his Night Fury will hold that special place in his heart.

There was just one thing Hiccup never really understood. While all the other Persona, and every other Shadow happened to be classified by Arcana, he could never really figure out where the Night Fury fell in the scheme of things. He couldn't possibly be without an Arcana, but it still wasn't identifiable. Elizabeth and Igor were no help, the bunch of (then) slack-jawed ninnies. That dragon was a complete enigma to everyone, but it mattered not.

His dragon. His Night Fury. His Toothless. Damned his other more "human" teammates. Thinking back on his very first encounter, he could still hear those words echo out under the first full moon of his year-long adventure:

"Thou art I and I am thou. From the sea of thy soul I cometh. I am Toothless, nommer of fishies!"

Together, both human and dragon as one, on this fateful day of January 31st, they face that which dared to desecrate the world the two shared. On that day, the two of them alone, rose among the stars to defend all life. To ensure that humans, full of dreams, hopes, and desires, may continue to dream, to hope, to desire. To ensure that all the fishies in the streams and seas will continue to swim, to swim, and... uh. To swim? Ahem. Together, they ensured that for all life, that there will be a February 1st.

And all the while, deep in the mind of Hiccup but unbeknownst to him, Toothless was thinking the same thing. All of dragonkind will be safe. And all of fishkind will be safe.

For delicious nomming.
