Remember the first time you played Ocarina of Time and running across Hyrule Field? "Oh look at that over there! I'm gonna go check it out! Oh what is that? Hmm AAHHHH! NO! NO! NO! DON'T KILL ME DON'T KILL ME PLEAASE!" Yeah. Well this Peahat isn't from OoT, but it still has the same effect.
In Majora's Mask, Aveil is the leader of the Gerudo Pirates. She has a room deep inside the Pirates' Fortress that is filled with all kinds of treasures and luxuries that the pirates have stolen, including a Zora Egg and the Hookshot. 
The ghosts, according to Romani, are the rather strange spirits that come to invade the barn of Romani Ranch to abduct their rare, precious Romani-bred cows, which they inherited from their father. They resemble ghostly, glowing aliens, and are quite similar to Poes. According to Romani, they come at night every year when the Carnival of Time approaches. They disappear at first light, just before dawn. If Link fails to save the cows on the first night they will abduct Romani, leaving Cremia, Romani's sister, saddened. On the second day, the ghosts will return Romani with all her memories of their existence removed,with apparent side effects on her personality. 
In Twilight Princess, Darknuts remain one of the most powerful enemies in the game, becoming even harder than their The Wind Waker counterparts. They still retain some of their characteristics like removable armor and high defense, but now have increased speed and more sword techniques. Its armor has become less bulky and more streamlined like a medieval knight. They still use a large sword and shield. Midna does not know how to beat them, but suggests to Link he try using all of his sword techniques.
Octives submerge into the water when approached by Link and will shoot rocks at him once he is within their shooting range. Octives act similarly to Octoroks, as they are both water-borne, projectile-shooting enemies. These enemies will dive back under the water if Link comes too close, so Link must reflect or blow their projectiles back into their face to defeat them. 
Saria is a Kokiri introduced in Ocarina of Time. She is Link's childhood friend from his years in the Kokiri Forest. She is well-liked amongst other Kokiri, in particular by their boss, Mido, whose dislike of Link might be partially explained by the latter's close friendship with Saria. She often travels to the Sacred Forest Meadow to play her Ocarina. She plays a lively, upbeat song that inspires people to dance called "Saria's Song." When Link becomes the Hero of Time, he rescues Saria from the Forest Temple and allows her to awaken as the Sage of Forest. 
The Eyegore first appears in A Link to the Past, known as Rocklops outside Japan. They can be found within early Light World dungeons (Eastern Palace, Desert Palace, and also in Ganon's Tower). They are one of the strongest regular enemies in the game, dealing a whole heart worth of damage even early in the game, and are surprisingly fast. Green Rocklops can be defeated by using a sword, when their eye is open but they are incredibly durable. A thrown pot or an arrow straight in the eye results in a quick defeat. Red Rocklops are completely immune to all attacks when their eye is open except for the Bow's arrows. Two arrows will defeat a Red Rocklops.
Cyclok, Stirrer of Winds, is the second boss in Phantom Hourglass, and appears in the Temple of Wind. 
He is the captain of the steamboat, the S.S. Linebeck, which Link uses to travel the Great Sea for the full course of the game. Linebeck travels the world seeking treasure, which seems to be his driving force in everything he does, including accompanying Link. People on the islands he visited seem to have a respect or admiration for him, calling him brave and wishing to travel the seas like him. However, Link and Ciela, while journeying, see a different side of him, different from the persona he puts up as a brave adventurer (at one point he claims to go through two dungeons a day before breakfast, though nobody seems to believe him). Instead Linebeck shows himself to be for the most part a coward, running away from trouble and staying with his boat instead of going into the dungeons with Link.
In Ocarina of Time, King Zora sits on his throne at the helm of Zora's Domain, guarding passage to the great Lord Jabu-Jabu, the patron deity of the Zoras. Only when Child Link presents him with a letter from his missing daughter, Princess Ruto, who claims to be inside Lord Jabu Jabu, does he grant Link passage to Lord Jabu Jabu's lair. When Adult Link ventures to Zora's Domain, he finds King Zora and the rest of the region frozen solid: a curse placed on the region that stems from Morpha's control of the Water Temple, the source of their water. Freeing King Zora from the ice after completing the Ice Cavern will grant Link a Zora Tunic as a gift. If Link already has a Zora tunic, he will offer him a kiss.
Gargantuan Masked Fish: Gyorg (Pronounced /ɡaɪ.ɔːɹɡ/, geye-org) is the third boss in Majora's Mask, located in the Great Bay Temple. It appears in the form of a giant chimaera. It is Gyorg who imprisoned the third of the Four Giants. Without its guardian deity, the waters of the Great Bay Coast become polluted and dangerous. This also causes an abnormal climate shift in the Great Bay area. 
Majora's Mask occurs after Ganondorf's defeat in Ocarina of Time and Link has been sent back to his childhood in the Child Timeline branch. After having been sent back to his childhood by the adult Princess Zelda of Ocarina of Time, the Hero of Time began a new history in which Ganondorf never destroyed Hyrule Castle and failed to take over the kingdom for 7 years. He leaves Hyrule to search for his lost friend Navi. While riding deep in the Lost Woods, he is ambushed by a Skull Kid who is possessed by an evil artifact, Majora's Mask, and his horse, Epona, is stolen along with the magical Ocarina of Time. Chasing the Skull Kid, Link falls into a crevasse and arrives in a world called Termina. He must save this land from the evil of Majora's Mask, which has drawn the moon into a decaying orbit, causing it to crash into Termina's capital city in just three days. Link uses the Ocarina of Time (reclaimed early on) and the Song of Time, which sends him back in time and saves the game when he plays it, to relive these three days again and again in order to prevent the disaster. Along the way, Link finds many magical masks of his own, a handful of which allow him to transform. Those masks can turn him into a rock-like Goron; a petite, plant-like Deku Scrub; a graceful aquatic Zora; or the Fierce Deity allowing Link to assume a powerful form, Fierce Deity Link.
Cannon is a bomb seller from The Wind Waker that lives on Windfall Island. When Link first meets him, he acts rude and disrespectful towards the young hero, saying he only sells bombs to those he approves, and he doesn't approve of Link. He sells bombs at ridiculous prices (i.e. 10 bombs for 10,000 rupees), which is the reason why Tetra and the pirates tied him up, gagged him, stole the bombs and left him alone in his shop. The reason he sells bombs at such high prices is because he is the last person in the world who still works in the bomb industry, allowing him to establish a monopoly on the business. However, after having the experience of being tied up by the pirates and having his bombs stolen, he becomes a much nicer, respectful person, stating that the policy in the Bomb Shop is kindness. Furthermore, he lowers the prices of bombs, this time only ranging from 10 to 30 Rupees
Byrne (Pronounced /ˈbɜːɹn/, burn) is a character in Spirit Tracks. He is a servant of Chancellor Cole, as well as the boss of the final floor of the Tower of Spirits. When Link, Princess Zelda, and Alfonzo are on their way to the Tower of Spirits, they are confronted by Byrne and the Chancellor. As a result, he captures Zelda's body after her spirit was separated from her body.
In The Wind Waker, pigs are generally peaceful animals that struggle in vain when picked up. They come in three varieties: pink, black, and pink with black spots. The easiest way to pick up a pig is to sneak up to it. An alternative would be to chase it into the water and wait for it to come back to shore, where Link can pick it up before it starts running away. Pigs love to eat, and if they are fed All-Purpose Bait, they might dig into the ground and release some rupees and items. If a pig is attacked too many times, it turns red in anger and relentlessly retaliates against Link. If there are any nearby pigs, they will also attack him, much like the Cucco's Revenge Squad. The pigs will stop chasing Link if he enters a building or goes to a place where they can't reach him, like on top of a high object or in a body of water. 
The Compass is an item found in dungeons that lets Link see the hidden Treasure Chests in a dungeon on the Dungeon Map. It also indicates where the boss is located. It is found in most main series games. 
Alfonzo is a Royal Engineer in Spirit Tracks. In the past, Alfonzo was known as the greatest swordsman in all of Hyrule and used to serve the Hyrulean army, as did his ancestors; however, he left his position there for reasons unknown to become a train engineer instead. He lives in Aboda Village, where he acts as Link's mentor as he trains the young hero to become a successful train engineer.
In The Wind Waker, Wizzrobes are characterized by their toucan-like heads. They usually wear dark cloaks with a red hood. There are also three groups of Wizzrobes that wear white cloaks and are found on top of the three triple-platforms in the Great Sea. There is also a more powerful version of the Wizzrobe, who wears a red cloak and an Incan-like crown. It is the mini-boss in the Wind Temple. He has the sole power of summoning other Wizzrobes, as well as enemies such as Darknuts and Moblins. A one-hit kill, even for the Wizzrobe mini-boss, is to freeze it with an Ice Arrow, and toss it at a wall or crush it with the Skull Hammer. When Link defeats this mini-boss, he receives the Hookshot.
White Wolfos, as the name describes, are snowy, sometimes anthropomorphic wolf-like creatures that take to icy climates such as the Snow Realm in Spirit Tracks and Snowpeak in Twilight Princess, however, these foes have been spotted in unlikely areas as well such as the Gerudo's Training Ground in Ocarina of Time. These creatures are usually common overworld enemies, nevertheless, in Majora's Mask, they disappear in Snowhead and the surrounding area once Goht is defeated, and only appear in the Ice Cavern of Ocarina of Time. In terms of appearance, the Twilight Princess incarnation inhibits a glow of sorts, adding to its enhanced realistic look, while the Spirit Tracks foes appear more cartoony to match the graphical style. It is interesting to note, that these White Wolfos have yellow eyes, while their previous incarnations have red eyes. 
Zelda sends Link on a mission to collect three Spiritual Stones and save Hyrule. Once Link obtains the Stones, he travels to the Temple of Time and opens the Door of Time with the Stones and the Ocarina of Time. He then draws the Master Sword from the Pedestal of Time. This action imprisons Link in the Temple of Light in the Sacred Realm for seven years so his body can mature, while Ganondorf takes control of Hyrule and seizes the Triforce of Power. Seven years after drawing the sword from the pedestal, Link is awakened as the Hero of Time by Rauru, Sage of Light. He sets off on a quest to cleanse the land of Ganondorf's evil by awakening the Sages, who can seal Ganondorf in what used to be the Sacred Realm. Returning to the Kokiri Forest, he finds that none of his friends have grown up, and most now no longer recognize him.
Lizalfos are lizard-like enemies with large tails, and usually wield large swords as weapons. In their Skyward Sword appearance, they wield large rocky gauntlets. It is common for Lizalfos to confront Link in pairs, but he will usually only have to actually fight with them one at a time. When one gets injured, it steps back and the less-injured one takes charge. They are very agile in combat and tend to swing their weapon at Link whenever they get a chance, but there are always opportunities to attack when they drop their guard. They tend to circle Link first and then approach on the counter attack. They sometimes move longer distances by hopping swiftly.
The Beetle is located in Skyview Temple. Link retrieves it after defeating a Stalfos in the central room located in the northern chamber, accessible after opening a door by pressing a nearby switch with a shot from the Slingshot. 
Pipit is a character featured in Skyward Sword. He is the resident bird expert of Skyloft and an acquaintance of Link. He is a senior student at the Knight Academy and wears a yellow tunic, the senior uniform of the previous year.
The Moblin is the primary muscle of Ganon's army. Common as foot soldiers and quite unintelligent, they've been around since the very first Zelda game where they started as anthropomorphic bulldogs. By Oracle of Ages and Oracle of Seasons, they were combined with Butablins, and took on a more piggish appearance. Other related species include the smaller but more intelligent Bokoblin, the tiny Miniblin, the huge Big Blin and Great Moblin, and the more militaristic Bulblin. Moblins have appeared in most games in The Legend of Zelda series, except for Majora's Mask, Four Swords Adventures, Twilight Princess, Phantom Hourglass and Spirit Tracks. 
Rupees are the unit of currency within most of the Zelda universe, in circulation in the lands of Hyrule, Koholint Island, Termina, Labrynna, Holodrum, the Great Sea, the World of the Ocean King, and Skyloft. 
Impa is the family name of several female members of the Sheikah, a mysterious tribe that has served and protected the Royal Family of Hyrule for many generations. Every member of the Sheikah tribe so far has been associated with and taken on the role of taking care of an incarnation of Zelda, being a nanny and a bodyguard of sorts in some games. As well as this, every Impa has given extensive information and guidance to the various incarnations of Link they encounter in their time. 
While Link is in a Silent Realm, he has to collect Sacred Tears to successfully complete the trial. The Guardians will try to prevent him from accomplishing that goal by chasing him as soon as Link leaves the safety of the circle he starts in. If they land a single hit on him, Link's spirit will shatter and he will have to restart the trial. Link can stop the pursuit by collecting a Sacred Tear, which will return the creatures to their inert statue-like state for 90 seconds. A flower above the Spirit Vessel acts as a timer, with its petals disappearing to indicate how long the Silent Realm Guardian will remain inactive. If Link is spotted by a Watcher or touches Waking Water, the effect of the tears will be nullified and the Guardians will reawaken, resuming their search for the young hero. 
A Crest is usually dropped by Darknuts, though occasionally Link will find them in chests, such as in Dragon Roost Cavern and Forbidden Woods (in both cases, near the Boss Room's entrance door). It is the symbol of courageous knight, and can only be collected by one who possesses the attributes of power, wisdom, and courage. Acquisition of these Crests was the motivating force behind Orca and Sturgeon's travels as young men. They aimed to gather ten Knight's Crests, but grew old before this dream was realized.
The Octorok is a conventional, octopus-like enemy, that (as its name suggests) attacks by spitting rocks. It has appeared in every Zelda game to date except Twilight Princess and has changed quite dramatically over the course of the series in terms of physicality and coloration. 
Ghirahim (Pronounced /ɡɪə.ɹɑːˈhiːm/, geer-rah-HEEM)is one of two primary antagonists featured in Skyward Sword. He is a figure of authority in the land below Skyloft, and he thinks quite highly of himself, preferring to be called Lord Ghirahim. His main objective is continuously hunting for Zelda, in order to use her spirit as a goddess for his plan to resurrect his master, Demise. Although at first Ghirahim thinks little of Link and his presence, the Demon Lord grows frustrated and erratic as he realizes the young hero is an obstacle to his plans.~Zelda Wiki
A Skull Kid is what a child becomes after getting lost in the Lost Woods; at least one Skull Kid appears in Ocarina of Time, Majora's Mask, and Twilight Princess. They first interact with Link in Ocarina of Time, and later a Skull Kid plays a major role in Majora's Mask. Skull Kids dress in a red cloak and hat covering an under layer of clothing comprised of a straw-like material (much like scarecrows), and play a flute, which they can also use as a weapon to shoot projectiles.~Zelda Wiki
Link is ranked 16th on the tier list, having so far his best performance in the series, due to the buff he received from the Super Smash Bros. to Melee. Despite his attacks being slightly weaker, they are faster. He is one the most reliable edgeguarders in the game because of his extremely powerful semi-spike and significantly better recovery (from worst to one of the best). However, he is large and is a somewhat of a fast-faller and as such, he is vulnerable to chaingrabs, which is a major problem in competitive play, resulting in Link being a low tier.~Zelda Wiki 
In Ocarina of Time, Sakon plays a significantly minor role. He can be seen running around the Hyrule Castle Market looking very suspicious, so it could be assumed that he is either buying things or stealing from the stalls. If Link talks to him is only line is "I'm late... I'm late for a very important date!", a reference to the White Rabbit from Lewis Carroll's Alice in Wonderland. In the ending credits, he can be seen dancing around joining in with the party. ~Zelda Wiki
In The Wind Waker, the Great Valoo is the almighty Sky Spirit. The dragon Volvagia is thought to be his ancestor.
