Monsters like Iron Giant carry 20-foot-tall swords bigger than they are; and as evidenced by the E3 2013 gameplay demo, the party can use these swords in finishing moves against the monsters carrying them.
Noctis, an attractive young man with a tall, slender figure and beautiful blue eyes.
The chocobo-blond-haired Prompto has a similarly svelte build and delicate features.
The pair of them are frequently compared to members of a boy band by fans.
Black and Gray Morality: Despite fighting an invasion of your country, you're essentially the heir to a family of crime lords.
Although a lot of the scenes shown to date with Regis make it more "Black-And-Light-Grey"; Regis himself is clearly shown to be the very opposite of a ruthless crime lord (going so far as to help young Noctis enjoy some bad soup so that the chef isn't fired), despite what his family history may be.
Somewhat subverted. The family aren't crime lords, but operate in a similar manner. The only stated details are that Noctis's friendship with Ignis, Prompto and Gladiolus had been compared to the "brother" concepts.
It should be noted that, at face value, the game has not shown any of the mythology or any of the roots of the characters. At worse case scenario, given what happened in Lightning Returns and the sister games, the perspective is currently locked in "Black-And-Dark-Grey", although it is even more likely to switch between Grey and Grey Morality and even Evil Versus Evil.
Faceless Mooks: Many of the human enemies you face wear armored helmets that cover their faces.
Foreshadowing: Remember back in 2006, when the game was first announced, that the game was supposed to take place somewhere along the lines of Like Reality Unless Noted, a distant relationship to myths despite having some connection to Final Fantasy XIII, and a myth where a door will burst open and souls will be guided to Etro's Gate? Come Lightning Returns, and you have an ending where the universe looks like it is being remade as the modern world, the crystal tales falling into a deep mythology and rendered free from Gods, all of this happening after souls were guided to this new world.
Light Is Not Good: Idola and some of the other villains wear white clothing, in opposition to the heroes' black outfits.
Lonely Piano Piece: The first half of "Somnus", which is a single melancholy piano melody playing slowly and softly.
The Mafia/Yakuza: Noctis and his enemies come from crime families with Italian names and stylings. However, elements of Japanese criminal organizations are featured as well.
Man in White: Idola, one of the mysterious antagonists in white robes.
Meaningful Name: Most of the characters' names relate to their roles or personalities:
Noctis Lucis Caelum is an incorrectly translated Latin phrase for "light of the night sky." He's actually supposed to contrast both Sora and Cloud.
Stella Nox means "night star" and Fleuret is French for a type of rapier, her weapon of choice.
Ignis Scientia means "fire of knowledge", since he's The Smart Guy who uses fire magic.
Gladiolus Amicitia means "little sword of friendship", ironically referencing his use of greatswords and his position as Noct's best friend.
Idola is Latin for "spectres", befitting his eerie quality and white clothing, as well as the game's overall theme of death.
Tenebrae (Stella's home) is Latin for "darkness", and Lucis (Noctis' home) means "light."
Other countries mentioned are Niflheim (a military dictatorship) and Solheim, which are Old Norse for "home of mist" and "home of sun."
Meaningful Rename: The title's rebranding is presented as this in the trailer shown at E3 2013. When the logo of Final Fantasy Versus XIII appears, the following quote is spoken, and then it shatters and is replaced with the new letters of Final Fantasy XV.
"The legend meets its match. But, the world is ever changing... For the fifteenth coming."
Mini-Mecha: 12-foot-tall robots serve both as enemies and rides you can steal.
Rule of Symbolism: Noctis and Stella are contrasting each other at Faux Symbolism levels: male and female, black and white clothes, blue aura and gold, and so on.
Seer: Both Noctis and Stella are able to foretell people's deaths. This is the mystical 'gift' Etro gave to them. A trailer shows that their reactions to this vary; Stella is confident and wants to talk about it, Noctis shies away from the topic.
Scenery Gorn: The empty and ruined landscapes outside the cities, such as crumbling desert highways that have sunk into the sea.
Scenery Porn: Accordo features gorgeous Renaissance-style architecture based off Venice, and Lucis is a haunting neon cityscape based on the Shibuya district of Tokyo.
Serial Escalation: One of the main reasons why the game was moved over to the next generation of consoles? The game was too big. Set pieces now involve fighting giant sea serpents, dozens of airships and entire armies, a far cry from self-contained turn based battles of earlier Final Fantasy titles. In addition, the "Luminous" next-gen rendering engine has made in-engine gameplay indistinguishable from the pre-rendered CG of earlier FF games.
Stepping-Stone Sword: Although he'll initially dangle helplessly after warping halfway up a building and stabbing his blade into the concrete, Noctis can also swing himself onto the sword and continue throwing weapons to create a sort of ladder.
True Companions: Prompto is stated to be an "old school friend" of Noctis, while Ignis and Gladiolus are his childhood friends. They have such a close friendship that they informally advise Noctis that he's not strong enough to handle himself in a proper fight.
