Manchild: His gestures and mannerisms are still child-like when older, although it's not really his fault, since his mindset was not given time or the opportunity to age due to being asleep for seven years.
Sealed Good in a Can: When he withdraws the Master Sword, he turns out to be too young to be the chosen hero. Thus his spirit is sealed away for seven years while his body matures to be old and strong enough to fight Ganondorf the way he needs to.
Would Hit a Girl: He has to as he's releasing Jiro and his carpenters after they were all kidnapped by the Gerudo Bandits. He also does this with the Poe sisters and Twinrova (Kotake and Koume).
Younger Than They Look: While Link's body aged 7 years, his mind was frozen in time, so mentally, he's this. Ironic, as the Kokiri are typically Older Than They Look. Although, the implication is that, while a child, Link is fairly mature for his age.
Captain Obvious: Mostly due to her not being programmed to recognize the player's location when giving advice. (Like when she tells you to go to Kakariko Village even though you're already there.) However, the first dungeon has a bit where she tells you that you need a key to open a door with a chain and lock on it, which will undoubtedly prompt you to respond "No, really?" or some other variant.
Nice Girl: The few chunks of dialogue that reference Navi (mostly by the Deku Tree) or are her talking about herself strongly hint at her being meant to be one of these. This is in sharp contrast to every other Fairy Companion in the franchise (Manga and Cartoon counting), who all feature at least a certain degree of temperament.
Unlucky Childhood Friend: Word of God reveals that she had feelings for Link, but he doesn't appear to reciprocate (though knowing Link, it's hard to tell). At the end of the game, Navi disappears in the Temple of Time, so things didn't work out well for her and Link.
Voiced by: Jun Mizusawa
The Princess of Hyrule. Despite her young age, she is wise beyond her years. She is aware of Ganondorf's plans to conquer Hyrule the entire world and she has her own plans to stop him.
Badass Princess: To some extent. Not only was she running around Hyrule disguised as a Ninja, but she also helped out a bit in the final battle, where she helps unlock the barriers keeping them from escaping the castle and helps Link pin Ganon down so he could land the final blow. She improves in this area over time.
Barrier Maiden: She and the other Sages seal away Ganon after Link defeats him. In the timeline where Link dies are forced to seal him in the Sacred Realm instead turning the holy place into the Dark World.
First, her plan to safeguard the Triforce by gathering all the Spiritual Stones together backfires as it allows Ganondorf to simply walk into the Sacred Realm after Link used them..
Second, by sending the Hero of Time to the past, nobody was around to stop Ganondorf when he came back, leading to Hyrule being destroyed and setting up for The Legend of Zelda: The Wind Waker.
And finally Because Link somehow got his Triforce of Courage when he came back, the Triforce got split anyway allowing Ganondorf to gain the Triforce of Power, survive execution and start the plot of The Legend of Zelda: Twilight Princess.
I Never Told You My Name: Sheik lets a single "Link" slip at the end of the first "conversation' with Link in the Temple of Time despite being literally the first person to encounter him in the future and no else seeming to recognize him from when he was a child. An early indication that Sheik is someone you know.
The last of the original Sages remaining, and the Sage of Light. Rauru explains to Link that he sealed Link away for seven years in the Sacred Realm so he could age into the intended Hero of Time, that Ganondorf has taken over Hyrule, and assigns him to awaken the reincarnations of the remaining sages.
Link's childhood best friend. She is later revealed to be the Sage of Forest.
Fan of Underdog: A slight example; when Link was a kid and didn't have a fairy, he didn't have any friends in the village...except Saria herself, who (partially) raised him as a baby and when he was her age she went out of her way to be his friend when the rest of the Kokiri shunned him.
Older Than They Look: Kokiri don't age, so it's possible that Saria was older than ten years old when Link was a child. She's at least Seventeen by the Time Skip, despite still looking like a ten year old.
Parental Substitute: It's possible that she was the one who raised Link since she's so close to him.
Plucky Girl: She made her way through the monster infested Forest Temple, which must've taken a lot of courage. She was also a loyal friend to Link, not caring that he was considered an misfit by the other Kokiri.
The chief of the Goron people. He at first rejects Link, but later comes to accept him after he clears Dodongo's Cavern of monsters. He gives Link the Goron Ruby and inducts him in as a member of the tribe. Seven years later, he attempts to rescue his people from the dragon Volvagia by going to the Fire Temple. He is revealed to be the Sage of Fire.
Action Dad: Having a son didn't stop him from going to rescue the rest of his people.
The Big Guy: He's not only physically imposing, but is very strong.
Last of Her Kind: The last surviving member of the Sheikah. For real, given Sheik is just a disguise.
Legacy Character: Impa is a name given to all of Zelda's caretakers in the series. Although, it was implied that this Impa is the same one who appeared in the backstory of the original Legend of Zelda.
Ninja Maid: Without the costume, but seeing that she is Zelda's nursemaid, she still qualifies.
Team Mom: She's Zelda's nursemaid. It's possible that she taught Zelda to disguise herself and the ways of the Sheikah.
The second-in-command of the all-female Gerudo thieves who secretly despises Ganondorf. She attempts to break into the Spirit Temple to retrieve the Silver Gauntlets, but is captured and brainwashed by Twinrova instead. She is revealed to be the Sage of Spirit.
Commander Contrarian: To Ganondorf, before she becomes a Sage. Zigzagged by the fact that her misgivings about Ganondorf are legitimate concerns and that her motivations aren't fundamentally evil, unlike his.
Screw the Rules, I'm Doing What's Right: As she stated to Link, she knows that Gerudo law requires that she bow down to Ganondorf due to his being the first male born in a century to the group, but she doesn't care and will not acknowledge Ganon as her king due to the atrocities he committed.
The guardian spirit of the Kokiri tribe. He is cursed by Ganondorf at the beginning of the game, and dies shortly after Link breaks the curse. A new Deku Tree grows in his place when Link is older, which retains all memories from the first, who tells Link that he is a Hylian and not a Kokiri.
Fisher King: Once the Deku Tree dies, Kokiri Forest goes to seed.
Genius Loci: He's a sentient tree so big he serves as the first dungeon, and the wisest you'll ever see.
You Are Too Late: After Link breaks the curse, he reveals that even before Link started, he was suffering from for so long that he was going to die regardless and that the whole affair was to see if he was capable enough for his quest.
The children of the forest who are under the protection of guardian fairies and the Great Deku Tree. They aren't allowed to leave the forest. They don't age, keeping the appearance of children.
Creepy Child: Fado, the blonde Kokiri Link meets in place of Grog. She states that everyone who enters the Lost Woods turns into a Stalfos. She ends the conversation by asking Link if that will happen to him, too.
Hidden Elf Village: The Kokiri village is hidden in a forest southeast of Hyrule, and is normally forbidden to non-Kokiri.
Jerk with a Heart of Gold: Mido definitely. It's implied that he has antagonized Link in the past and continued to do so in the beginning. However, he seems to like Saria and even promised to guard the Secret Forest Meadow for her. In the future, he voices his regret for picking on Link and never apologizing to him.
The wise old owl who shows up around Hyrule. He appears to give the player hints as to where to go next and what to do. However, his long-winded text conversations and Exposition Break manner of speaking made him annoying in any playthrough but the first one.
Ship Tease: The way she calls Link "fairy boy" can be taken as being a sign of a crush on Link. Also, the revelation in Hyrule Historia that the rancher Link from Twilight Princess is a direct descendant of the Hero of Time seems rather suspicious...
Shout-Out: Wears a broach of Bowser's face on her ascot.
Brainwashed and Crazy: Ganondorf brings out Ingo's resentment toward Talon and makes him evil in the adult years. He gets better after you defeat him in a race and get Epona. This is more obvious in the manga than the game.
Let's You and Him Fight: Sharp and Flat will attack you on sight, believing you to be a follower of Ganondorf. They'll only realize you're not after being defeated. They're also among the few people who recognize Link as an adult.
Magic Music: Together they composed the Sun's Song, which can summon the day and the night.
Meaningful Name: Sharp and Flat are musical terms, thus fitting names for composers.
Proud Warrior Race Guy: The Gorons as a whole actually don't seem to exhibit this trait. While later games would see them becoming more warlike, the Gorons in this game are a fairly laid-back and peaceable society who frequently need the help of a more-warlike visitor to bail them out.
Verbal Tic: They commonly tack "-goro" onto the ends of their sentences or words.
Adipose Rex: King Zora. He's so fat and huge that just moving to the side to let Link pass behind him (with a pretty funny "Ouweep" sound) takes a while.
Fish People: Unlike previous Zoras from the previous games, these Zoras are much more beautiful and human-like. This is because they are Sea Zoras, while the much uglier and monster-like enemies are River Zoras.
Non-Mammal Mammaries: Judging by Ruto and the Zora females seen in other games, this is typical of the race.
Our Mermaids Are Different: They have traits of mermaids as well as Fish People. They have legs with flippers, sea resistant skin and can breathe underwater. They have the tail of the aquatic animal they're based on instead of hair. They are able to live on land, but can dehydrate quickly.
Sealed Good in a Can: The entire race gets frozen into the ice of their aquatic home by Ganondorf, though they probably aren't conscious for it. The only ones to escape this fate are King Zora, who's frozen in red ice and can be rescued with blue fire, and Princess Ruto, who is ultimately saved from the ice by Sheik.
A giant fish/whale hybrid. To acquire the Zora Sapphire, which he swallowed, Link must go into his belly and find both it and Princess Ruto.
The Assimilator: In Master Quest there are cows being absorbed alive into his stomach lining.
Amazon Brigade: The entire race is female, and it is required by law that they obey their king, the sole male born in 100 years.
Brainwashed and Crazy: Shortly after Link kills Twinrova, one of the carpenters would tell Link when spoken to that with Koume and Kotake dead, the Gerudo are no longer scary anymore, implying that their earlier actions were the result of Twinrova brainwashing the race or keeping them in line with fear.
Even Evil Has Standards: It's subtly implied that the Gerudo may not have actually wanted to serve Ganondorf in the adult years, as they were seen celebrating Ganondorf's defeat at Lon Lon Ranch. Granted, they weren't quite as brave about it as Nabooru, who was willing to defy him and their ancient traditions, but still.
Fantasy Counterpart Culture: They have a vaguely Middle Eastern culture (being desert-dwellers) with a star and crescent as their symbol.
One-Gender Race: Save for the exception noted above. Gossip stones imply that they tend to marry (or at least seduce) men from the rest of the country to propagate themselves. Only one male Gerudo is born every hundred years and he is to lead his female companions. Ganondorf is this man during the events of the game.
Punch Clock Villain: They only seem to be going along with Ganondorf's plans because he's their king. It's implied that they were brainwashed. After Link frees the carpenters, they see him as a Worthy Opponent and stop attacking him.
"As I thought, you held the keys to the Door of Time! You have led me to the gates of the Sacred Realm... Yes, I owe it all to you, kid!"
Ganondorf, King of the Gerudos, and, not much later, Great King of Evil. He seeks the power of the Triforce, but, due to his unbalanced heart, causes it to split into its three basic components, and is only able to seize one of them: The Triforce of Power, the one virtue most prevalent in his heart. Of course, one third of the power of the goddesses isn't a bad share on its own, granting him tremendous physical and magical power and making him nearly immortal, and with it he easily takes over Hyrule in the seven years of Link's absence. However, just one piece of the Triforce still isn't enough to grant him his wish. And so, his search for the remaining pieces continues...
Zelda: Ganondorf... pitiful man... Without a strong, righteous mind, he could not control the power of the gods... and...
Ambiguously Brown: Him and all the Gerudo people. They live in deserts, so it's probably justified. Ganondorf himself, however, has a sickly green tone to his skin. By the end of the game, it has already turned into full-blown green skin.
Archenemy: This is where his centuries-long antagonism to many Links and Zeldas to come began.
Badass Baritone: Befitting an evil and badass character like him, his voice is pretty deep.
Determinator: While prone to getting overconfident, he doesn't quit when things get difficult for him. Even losing a fight with Link and being crushed by his own castle, he still refuses to give up.
Devil in Plain Sight: Both the child and adult timelines. See Obviously Evil for the first. In the adult one, everybody seems to know where he resides, but seeing as he's in castle floating over a giant lava pit, even Link can't go after him for most of the game.
Dual Wield: Does this when he finally transforms into Ganon in the final battle.
Dying Curse: He swears to destroy all of Link and Zelda's descendants just as he is being sealed. This mirrors the curse that Demise placed on their ancestors in Skyward Sword.
Genius Bruiser: He's an incredibly powerful sorcerer, and also a powerful warrior. In addition, he is also a pretty good strategist. It's heavily implied that he used both Zelda and Link to access the Sacred Realm. And then years later he uses Link to reveal Zelda's location.
Impaled with Extreme Prejudice: Variation: Link, after Ganon was pinned down by Zelda, delivers the final blow by impaling his mouth. In the 3DS remake, the final blow was changed to impaling his forehead instead of the mouth, presumably to have it match the way he is killed in Wind Waker.
Load-Bearing Boss: As you defeat him, he casts a spell which causes his castle to crumble, in an attempt to bury Link and Zelda. Sadly for him, it fails. Sadly for them, it also fails to kill him.
Magic Missile Storm: His Desperation Attack as Ganondorf is to gather a large orb of power and fire five of his energy orbs at once. Ironically this is easier to deal with than his standard attack, as Link's Spin Attack will deflect all of the bolts and at least one is promised to hit him with no chance for him to reflect it. Or, alternatively, the attack's long charge time allows Link to be able to disrupt it from ever going off with a quick light arrow, stunning Ganondorf and allowing him to be attacked with Link's sword.
Physical God: Almost literal considering what powers him now.
Pig Man: The rare Big Bad example of this trope. Although how much he resembles a pig is open to interpretation. The artwork for the game (see above) gives him a slightly piggish nose, but even his in-game model doesn't look so much like a humanoid pig as some kind of demonic, non-descript Beast Man.
Prongs of Poseidon: The Trident of Power. Though he himself doesn't use it in this game, his minion, Phantom Ganon, does.
Squishy Wizard: In contrast to his later appearances, he relies exclusively on magic and doesn't even carry a shown weapon. Though considering how durable he is, he still doesn't play the trope straight.
Tactical Suicide Boss: Two of three attacks he has in his humanoid for can sent back at him, and the only other one he has can't reach Link if he's too far away.
Villainous Breakdown: He's shocked at the fact that a mere teenager could defeat him. When he realizes Link and Zelda survived the castle's destruction, he gets pissed, his eyes glow, and he doesn't even say a word.
You Killed My Father: It's strongly implied that Ganondorf murdered Zelda's father, the king, around the time Link retrieved the Zora Sapphire.
Achilles' Heel: Din's Fire, the only attack/weapon Link has that he can't block, though he'll often still try and get hit, and the radius means he almost always gets hit.
Blade Run: Dark Link is capable of doing this if you use the stab move to attack him by freezing Link in place somehow and jumping onto the blade. This can be used to your advantage, however; if you use a broken "Giant's Knife" he falls off. However, if you haven't figured out not to stab him before his Turns Red phase and aren't using a broken Giant's Knife (which is quitepossible), he starts punishing your idiocy and will attack you while standing on your sword.
Mook Maker: After taking enough damage, she'll crawl up the wall and onto the ceiling, and start laying eggs which will hatch into enemies. You can break those eggs before they hatch, or even stop Gohma before she lays a single egg with a Slingshot seed to the eye.
Warm-Up Boss: Understandably for the first boss, Gohma is the easiest boss in the game. Her attacks aren't very damaging, and her weak spot is obvious.
Resurrected for a Job: Volvagia is an ancient evil that devoured Gorons alive until defeated by the Hero of the Gorons. Ganondorf revives the evil dragon to exemplify the fate of the races who opposed his despotic rule.
Giant Space Flea from Nowhere: While most bosses in the game have some explanation as to where they came from, this thing doesn't have any. It's not explained if Ganondorf created it or if something that just appeared.
An Ice Creature: It's strongly implied that it bore the brunt of the responsibility of maintaining the frozen state of Zora's Domain.
Mega-Microbes: Morpha itself isn't the huge water tentacle it creates, but the vulnerable eye-like nucleus that serves as the boss's weak point.
Murder Water: Though Morpha itself is just the nucleus, it manipulates the water as though it were part of him.
Its first appearance has it flailing Sheik around shortly after escaping the well, and throwing the hapless Sheikah down hard enough to induce unconsciousness. The exact result of Link's failed encounter with it is unknown (the screen blacks out right when it approaches Link), although the vocal grunts imply that Bongo Bongo managed to defeat Link easily in a similar manner, and it was implied that Link was knocked out for several hours as a result.
Incidentally, you can Curb-Stomp Battle Bongo Bongo right back with the use of a glitch that allows you to drop a bomb on its hitbox before you even enter the boss arena. The dropped bomb puts it into stun mode, and you can jump down and kill it near instantly. (seen at about 4:22:00 here)
Eldritch Abomination: Huge? Check. Terrifying? Check. Unknown origin? Check. Only able to be seen with a certain object? Check.
Mind Control: They use this on Nabooru (with the Hypno Trinket variety). It's also implied from one of the carpenters after her defeat that the Gerudo as a whole may have been brainwashed by her as well.
