An Ice Person: Xenos demonstrates incredible ice powers; "A gift from the Queen Dragon..."
Artifact of Doom: The Aurathon has incredible power, so great in fact that only the Dragon King can wield its full power. Or a 1,000 year old vengeful wizard of equal power.
Audible Sharpness: The various swords wielded by soldiers definitely give off a sound when unsheathed. Even Dev's scabbard gets one when a Vorgan knocks his sword out of his hand and uses the scabbard as a backup.
Back-to-Back Badasses: Dev and Kyra of course. Most notably after their duel when both their kingdoms' armies come to battle each other, the vorgans show up and they have to fight them off, ending up as the only human survivors left on the battlefield.
Xenos: I, who for 1,000 years have manipulated their ancestors like puppets. I killed their dragons and they blamed each other. I know how they think. I know how they feel. They are but weak humans. And they can do nothing!
Badass Family: Four of the main characters are the two battle-hardened kings and their children.
Badass Grandpa: While not technically grandparents yet, the two kings look old enough and fight well enough to fit this trope.
Battle Couple: Dev and Kyra obviously. Not only do they both have exceptional melee combat abilities but with their powers of wind and fire, they can combine them for some interesting and devastating results.
Beauty Inversion: Xenos gets a horrific example towards the climax after Kyra knocks off his youthful mask, revealing a horribly aged face.
Big Damn Heroes: During their Back-to-Back Badasses moment above, Dev and Kyra are being surrounded by an overwhelming army of vorgans and not a moment too soon does Xenos swoop in and wipe most of them out with a huge ice wave.
Blade Reflection: A reflected shot of Kyra's opening eye is shown after Dev appears to finish her off on the ground during their duel.
Bloodless Carnage: Justified for a children's film. Characters get stabbed, impaled, riddled with flaming arrows, and even crushed by a club the size of a human torso, yet not one speck of the sanguine delight can be seen.
Blow You Away: Dev's power is control over the wind. He uses it to devastating effect in the final battle, wiping out the remaining Vorgan army in one move.
Cel Shading: Something of a blend of pure black shadows with simplistic rendering.
Character Development: The two protagonists originally despise each others nations, but their experiences, naturally, bring them closer together, as well as both of the kingdoms entirely.
Chekhov's Gun: The unique personality traits of Dev and Kyra. Dev is a bit of an impulsive brawler and Kyra tries to fight fair all too much. This comes back and gets inverted during their duel. Dev passes up an easy kill and offers to help Kyra off the ground, and she responds by catching him off guard with a kick.
Cosmic Keystone: The Aurathon is the master key to open the portal between the human and dragon worlds.
Death from Above: The Vorgans pulls this off twice. First during the big battle in the beginning and second when they interrupt the heroes' training in the Ring of Ouroboros by bombarding it with exploding ice harpoons.
Dual Wielding: After Dev cuts Kyra's staff in half during their duel, she proceeds to utilize Kali Stick fighting style.
The Dragon: No matter what the title says, it's definitely not that kind of dragon. It's Gortaz, that head Vorgan that captures both the kings during the big battle after the duel.
Establishing Character Moment: The introduction scenes of Dev and Kyra as children show their basic personalities as impulsive and over-thoughtful respectively.
Family-Unfriendly Death: Most of the deaths happen off screen or just out of sight, save for one. A hapless Vorgan gets frozen by an ice dragon and knocked down a chasm, where it shatters into pieces, one of which was its skull attached to its spine, in full view of the audience, in slow motion.
Flynning: Justified in that it's a children's film, so having people exploit the oh-so-many obvious kill opportunities would be too grim for a young audience.
Horny Vikings: The helmets of both nations' armies have horns, more resembling of dragon horns, but horns nonetheless. Heck, one nation is even called Norvagen, and their king has a great long beard, and their weapons and armor lack any sophisticated articulation in design, and their city looks like a half-ruined castle.
Jerk with a Heart of Gold: Dev is certainly this. He intended to kidnap Kyra so as to force the Draigar to surrender, thus "ending" the war. But he really wanted the war to be over so he could see the sky filled with dragons again. It's even lampshaded later when Xenos uses a crystal to read his thoughts.
Load-Bearing Boss: After Xenos has been defeated and taken back to Dragon World, the temple begins crumbling apart. Justified in that it was made entirely out of ice, had sustained heavy damage from Thoron's multiple crashes through it, and it's likely that Xenos had probably used his ice powers to maintain it.
Manipulative Bastard: Xenos, who had, for 1,000, years manipulated the human nations, tricking them into killing off each others dragons to near extinction.
Mighty Glacier: Gortaz, the Vorgan leader. He can swat multiple human soldiers away with a single swing of his enormous club, catch a large sword in his bare hand, and snap said sword with one hand.
No Flow in CGI: Very few elements are actually physically dynamic, and even then they don't flow like they should. King Olsef's beard is cemented to his body, Dev's gelled back hair never changes, and Kyra's one-piece bob cut moves like a piece of thick rubber.
Oh Crap: Kyra's horrified expression after she knocks off Xenos' young mask, revealing his face that had been aging for 1,000 years.
Xenos gets one soon after when Thoron proclaims that even though Xenos has extracted the Aurathon from the two heroes, they still have their wind and fire powers. And they do. and Xenos gets some major egg on face.
Thoron: I beg to differ, traitor! They are Prince Dev and Princess Kyra! And They have been chosen by the dragons themselves!
Rebellious Princess: Kyra really wants to prove that she is the best fighter in her kingdom by facing Prince Dev one-on-one in a duel to end the war. Deep down though she really just wants the war to end so that the rest of the dragons will return to their world.
Sequel Hook: Just before the credits the camera travels through the portal from the human world to the Dragon World. We then see Xenos who looks at the camera while saying "This. Isn't. Over!"
It ends up being useless, since the sequel doesn't feature Xenos at all. Though we do get to see Stendahl, the evil dragon Xenos consorted with in the past.
She-Fu: Kyra is train in more intricate and elegant forms of martial arts. During her duel with Dev she does lots of flips and whirling kicks.
The Smurfette Principle: Kyra is the only female ever seen throughout the entirety of the film. Though some female voices can be heard cheering at the end.
Stripperiffic: Averted since it's a kid's movie. Kyra's outfit is mainly a one-piece body suit with some armor plating, and the visual style is very angular, diminishing any sensuality of her curves.
Take Over the World: Xenos wants to do this to both the human and dragon worlds for revenge against the dragons for granting him immortality but not eternal youth.
Tempting Fate: After The Reveal Thoron takes Dev and Kyra to The Ring of Orobouros to train their mysterious powers in secret.
Dev: I don't see what you're so worried about. You've got your strength back, we can control our powers, and Xenos, they don't even know we're here.
[Cue sneak attack by the enemies]
Kyra: Well, two out of 3 ain't bad.
Waif-Fu: Kyra is incredibly skinny compared to everyone else.
Weapons That Suck: All the human weapons are alright against other humans, but a metal-tipped staff can't survive a strong sword strike, and a strong enough Vorgan can catch a blade in one unprotected hand and snap it like a stick.
Weaponized Landmark: The Ring of Ouroboros, once activated by Thoron, the Dragon King, becomes an invisible training ground for Dev and Kyra to control their powers.
What Measure Is a Non-Human?: Xenos not only manipulated the two human nations into killing off each others dragons, but he used the bodies as food for his Vorgan allies.
Who Wants to Live Forever?: Xenos is known to have been given immortality by the Dragons so that he may serve as ambassador between the two kingdoms and the dragons for all time. By the time the film opens he notices the lack of dragons could allow him to finally retire. However, it doesn't stop 1,000 years of aging.
You Go Girl: Kyra, while respected throughout both kingdoms as a great fighter, is still forbidden by her father to face Prince Dev in a one-on-one duel. But that doesn't stop her.
Kyra: I'm the best fighter you have. You said so yourself!
Sidari: And you can prove that tomorrow, in battle, with soldiers beside you. As it should be.
Kyra: If my father won't issue the challenge.
Kyra: I'll challenge the prince myself.
You Have Out Lived Your Useful Ness: Once Xenos gets the Aurathon, he smooths out his crushed fortress, leading to Gortaz sliding to the edge of a deep opening. He asks for Xenos' help but Xenos decides to step on his hand, sending him to his doom.
