Hero with Bad Publicity: Kakariko Village has wanted posters for him due to the fact that he was framed for kidnapping Zelda after he rescued her from the castle's dungeon despite the fact it was Agahnim that did the kidnapping and put her in there to begin with.
More than Meets the Eye: Outwardly Link is valiant, virtuous and embraces his lineage to battle evil. In the corrupted Golden Land, Link transforms into a reflection of the heart, a harmless pink rabbit. He cannot fight at all in this form, revealing Link is a true pacifist, utterly opposed to war and violence. Unlike what the monstrous Ganon transforms into.
Leitmotif: Zelda's Theme. This is its the first appearance in the series.
Live Item: After you beat Turtle Rock, you can see Zelda in your inventory screen in a crystal.
Pimped-Out Dress: This game is one of the aversions for the series where in the official art, Zelda's standard clothes are rather plain. However, she does have a second outfit in the official art that fits this trope.
Save the Princess: Twice in the same game. Zelda starts out already kidnapped at the beginning of the game and you rescue her during the game's opening sequence. When you get the Master Sword after completing the first set of dungeons, Zelda gets kidnapped a second time.
"Pestilence and drought, uncontrollable even by magic, ravaged the land. The king of Hyrule, after counsel with his sages, ordered an investigation of the Imprisoned Dark World (as the Golden land had come to be known) but the wise men's seal was apparently intact. He offered rewards for anyone who could find the source of these troubles. In answer to these summons a stranger named Agahnim came and quelled the disasters with a previously unseen form of magic." —The A Link to the Past manual
"Ho ho ho... With this, the seal of the seven sages is at last broken. It is now only a matter of time before evil power covers this land completely...After all, the legendary Hero cannot defeat us, the tribe of evil, when we are armed with the Power of Gold. Ho ho ho... Now, I must go!" -Agahnim
The main antagonist of A Link to the Past. He is an Evil Sorcerer who masterminded a plot to conquer Hyrule by appearing to be its savior. The king is naturally a Horrible Judge of Character and makes him his adviser. Through false allegiance and his powerful sorcery, he took control of Hyrule Castle and used the Brainwashed soldiers of Hyrule in order to pursue his objective. Agahnim seeks to banish 7 maidens descended from ancient sages to the Dark World so the seal placed by the sages can be broken. When the seal is broken, evil power will cover the land and an ancient threat will rule the world as it intended to long ago.Unrivaled in terms of magical ability in all of Hyrule, in control of the nation's army and unable to be directly harmed even by the land's blade of legend, Agahnim appears to be unstoppable.Eventually, one of the crystal maidens reveal that the ancient Prince of Darkness, Ganon, was behind him the whole time. Except that it turns out Agahnim actually was an alter ego of Ganon that could exist in the Light World.
The Archmage: Agahnim's magic solved the plagues of Hyrule when no other magic could. He would go on to perform great feats of sorcery, such as mass brainwashing, transporting himself and others between dimensions and utilizing powerful offensive spells.
Badass: Agahnim does some very impressive feats of magic.
Dangerously Genre Savvy: In the tie-in comic adaptation, Agahnim is very competent. He personally kills Link's uncle, believing him the only last descendant of the Knights of Hyrule that could wield the Master Sword. When he gets reports of Link retrieving the first Pendant, he realizes that Link might be of the bloodline as well, and immediately sends his soldiers out to apprehend Link and burn the library, which holds the Book of Madora that contains the knowledge needed to retrieve the next Pendant.
Demonic Possession: The nature in which Ganon reveals himself, as well as some issues as to why Agahnim would reopen the Dark World if he was Ganon to release him if he was already freed of it anyways, is implied to be more of this trope than Ganon simply disguising himself as such. Later in the series, Ganon does explicitly show the ability to possess people in the form of Puppet Zelda in Twilight Princess.
The Dragon: Agahnim to Ganon. Subverted later when it is revealed Agahnim is Ganon's alter ego.
Evil Chancellor: Well, he did betray the king he acted as an adviser for by outright murdering him.
Evil Genius: Agahnim's knowledge of sorcery is the key to his power and his plan to imprison the Maidens in the Dark World does succeed despite Link's efforts to stop him.
Evil Plan: He plans to undo the Sages' seal. Zelda tells us he is very close to completing his plan right from the beginning of the game.
Evil Sorcerer: Arguably the best example in the Legend of Zelda series.
Fake King: Agahnim used this position and his powers to complete his objectives. This did not go entirely unnoticed as one castle guard commented, "After Agahnim took over, everyone began to act strangely."
Fisher Kingdom: Subverted. We see Agahnim cross from Hyrule to the Dark World, a place which physically alters the appearance of everyone who does not have a Moon Pearl, and Agahnim does not change at all.
Improvised Weapon: The game says the Master Sword is the only thing which can defeat Agahnim. Skilled players can use the Bug Catcher's Net to reflect Agahnim's orb attack back at him, which is obviously Not the Intended Use of the item.
This is also an Ascended Glitch with Link being able to use Bottles to reflect some of Ganondorf's attacks in Ocarina of Time, Wind Waker and Twilight Princess.
Let no Crisis Go to Waste: Agahnim's actions before the game started brought him much acclaim. He was famous for stopping a blaze and then he saved Hyrule from a rather mysterious pestilence and drought when no one else in the world could.
My Death Is Only The Beginning: Twice. Defeating him in Hyrule causes a portal to draw Link into the Dark World. When you defeat him in Ganon's Tower, he sheds his disguise and exposes himself as Ganon.
Nothing Can Stop Us Now: The only person who can stop Agahnim is the Hero of legend. Agahnim seems to think not even the Hero can stop him and his tribe.
"After all, the legendary Hero cannot defeat us, the tribe of evil, when we are armed with the Power of Gold."
Not Quite Dead: Link nearly kills Agahnim but the crafty sorcerer sends the hero to the Dark World before Link could finish the job.
The Pawn: Agahnim is presented as being Ganon's pawn and is called such by the rescued Maiden in Misery Mire. It turns out that Agahnim actually is Ganon, however, just with most of his power still sealed in the Dark World.
Sealed Evil in a Can: Agahnim works to break the seal of the sages. Doing so will unleash evil power across Hyrule.
Shock and Awe: Agahnim can summon lightning from his hands◊. However, it's easy to dodge because he only fires it when standing in the northern part of the room and he doesn't turn to aim it at Link like he does with his other 2 attacks, so Link can just move to the side of the room when he starts charging an attack on the northern side of the room.
Sinister Minister: In the Japanese version, he was a priest. This was changed because Nintendo's localizers had not yet outgrown their aversion to using religious terminology and symbolismnote in contrast to how Ocarina of Time was released after Nintendo did outgrow it, as the goddesses who created Hyrule are referred to as such in that game and Ganondorf refers to the Triforce as containing the power of the gods, just as the Japanese title of A Link to the Past did.
Tactical Suicide Boss: Despite having his one reflect-able attack used against him numerous times, Agahnim will continue to use it until he is defeated.
Teleport Spam: Agahnim teleports after nearly every attack, making teleporting the most common move he uses in battle.
Tempting Fate: Agahnim confidently decrees, "After all, the legendary Hero cannot defeat us, the tribe of evil, when we are armed with the Power of Gold." By the end of the game, Link has done just that.
Tennis Boss: The series' very first occurrence of a tennis boss is the first fight against Agahnim.
Treacherous Advisor: For aiding Hyrule and its people, the King appointed Agahnim to be his chief adviser. Things didn't go well afterward (see below).
The Usurper: Agahnim gets rid of the king and makes Hyrule Castle his base of operations.
Villain with Good Publicity: Link gets framed for kidnapping Zelda despite the fact that it was really this guy who at first simply locks her in the castle's dungeon, but later banishes her to the Dark World. Agahnim also has fame for ridding Hyrule of drought and pestilence.
Wake-Up Call Boss: So the bosses have been fairly easy up to this point. Just a few swipes of the sword and it was over. And now you have a better sword: the Master Sword, the sword of evil's bane. Too bad directly attacking Agahnim with it hurts Link, not Agahnim.
You Killed My Father: The opening of the game strongly implies that Agahnim murdered Zelda's father upon usurping the throne (The king is shown as a skeleton, among other things). Was also indirectly responsible for the death of Link's Uncle, who served as a father figure to Link.
The elder of Kakariko Village and a descendant of one of the sages who sealed Ganon. He serves as Link's guide through the game, communicating with him through telepathic tiles (though it seems as though touching the tiles just notifies him of when his assistance is needed, because when Agahnim sends Link to the Dark World Sahasrahla telepathically communicates with Link regarding his current situation despite there being no tile in sight).
Death by Falling Over: Those rats were just too much for your uncle to handle, although the game implies that he was killed in an ambush by Agahnim's forces. The tie-in comics elaborate that, because Link's uncle too was a descendant of the Knights of Hyrule, and thus a potential holder of the Master Sword, that Aghanim killed him personally.
A Manga-exclusive character. The descendent of another line of Hyrule Knights, he runs into Link in the Dark World. He's more focused on defeating Ganon than rescuing Zelda, and finds the idea that the immature and hotheaded Link could be the hero of legend laughable.
Archer Archetype: He's arrogant, he's a loner, and he's a crack shot with a crossbow.
