Anime and Manga
Used in Kidou Tenshi Angelic Layer, where the most powerful Deus had an Angel that could spontaneously grow wings. By the end of the series, so could the protagonist - but only in the anime.
The Destiny has physical wings that can briefly sprout a pair of red/pink energy wings◊. Aside from granting greater mobility, the energy wings also leave behind vibrant after-images that confuse eyes and sensors alike but guzzle power at an accelerated rate.
The 0 Gundam has a pair of seraphic wings in the first episode; Word Of God states that the "wings" are formed from massive GN Particleleakage. Why this would look like seraphic wings? Probably because angels are a central theme to the series.
The Throne Drei from the same series spreads false GN particles as an extremely effective form of chaff. What isn't justified is the emitters being arranged in such a way that the particle burst resembles a massive phoenix◊. The 00 Raiser gets its own version with Trans-Am Burst◊.
And while Nanoha herself doesn't do this, her staff Raising Heart does, the number and size of the wings it sprouts for any given spell are a good rough indicator of just how much someone's going to get hurt. Subaru's Mach Caliber has Gear Excellion, which is a blue version of Nanoha's and she uses it against her older sister Ginga, who's been Brainwashed by Scaglietti as a Number.
Sailor Moon has wings during her second transformation; for about 3 seconds before they disappear in a burst of feathers.
She also has wings on her Eternal fuku, but these appear to be purely decorative along with her Frilly Upgrade. Later on, when it's time for the final battle, she grows real wings. Her opponent, Sailor Galaxia, slightly subverts this trope and grows demon wings.
In the manga, every soldier can grow wings and fly in space, apparently. Moon, ChibiChibi, the Starlights, and Kakyuu at least do. I can't remember if the Sol senshi do at any point.
Tenchi Muyo!, where Tenchi and Juraian warships have the Light Hawk Wings.
Much like kitsune mythology, the number of Light Hawk Wings shows how much power one has up to nine wings. Three is the highest a mortal can possess; ten wings are worn by gods and goddesses. Tenchi's not mortal, as the final (current) episode of the OVA shows that Tenchi's now sporting five of those things. Ryoko (as the daughter of a goddess) will also be able to have ten of them when she reaches full maturity (if Tenchi gives her back her other two power gems, that is), but given that she hasn't done so yet after 5000 years, who knows how long that will take.
In the Trigun anime finale, Vash's and Knives' AngelArms are unleashed to the maximum level, and spontaneously sprout wings.
Very common in the Pretty Cure franchise: Since Fresh Pretty Cure!, every movie features the lead Cure getting an upgrade with wings which later appear in the final of each TV series, but that said upgrade includes the entire group.

Averted in Heartcatch Pretty Cure, where the the wings of their Super Mode are already featured before the movie was aired and the ultimate upgrade in the series is something completely different.
In Suite Pretty Cure ♪ movie, Cure Melody becomes Cure Crescendo Melody with two pairs of golden wings. The group gets this upgrade later in the final.

The Divine Cloths of the Saints in Saint Seiya are more powerful and winged versions of their normal armours.
No need to go as far as that. Every single time (particularly in the movies) Seiya's Cosmo burns bright enough to make him a real threat to the latest Big Bad, he somehow summons the Sagittarius armor to him to replace the Pegasus Cloth. The wings, golden halo, and bow and arrow seem designed to inspire an angelic symbolism.
To Aru Majutsu no Index provides a clear example of people who has started to reach the capability to understand the path of Heaven and God's will.
Aiwass also has Golden Wings hidden by his/her/it very long hair.
Index also grows Red Wings probably due to she is technically a God of Magic.
Rei Ayanami gets a set of six wings in End Of Evangelion before proving Freud Was Right for all eternity. Suitably, her Wings become so large, they can cover the Entire Earth.
Unit 01 and Shinji gain wings of pure energy when exiting the Geofront explosively, giving it a Seraph-like appearance. Except it doesn't really help, as he finds outside the reason why he fought—the last person who he thought alive who he cared about/loved/????—turns out to have been EATEN.( Asuka.) Poor bastard never gets a break.
For all the Power tropes simultaneously exhibited, the first thing Eva-01 does is become more helpless than it was the entire series.
Unit 01 also sprouts six energy wings in the opening, even tho that never occurs in the show itself (until the movie, anyway).
Also, Adam sprouted quite a few wings...probably six too, before it initiated Second Impact, wiping out half of humanity and messing up the World's Ecosystem permanently.
A more straight example appears in Rebuild of Evangelion after Eva-01 merges with Rei and the remains of Zeruel (who had been given a very epic ass-kicking from Shinji) and grows wings of energy.
Note that this almost causes the Third Impact, if it hadn't been for Kaworu turning EVA-01 off. Apparently, in Evangelion, wings forewarn a large-scale disaster...
Fanfic writers really like this trope in general, such as in the fic True Angel by Innortal, where Shinji has power that manifests retractible wings, which happen to be somewhat contagious, thus a power spike ends with several hundred random people getting their own wings.
Rin Asougi in Mnemosyne sprouts a pinkish-white pair of wings after becoming the new Guardian of Yggdrasil. It may be interesting to mention that there are "normal" Winged Humanoids (appropriately called "angels") in the series but their wings are bloody red in color.
In Shugo Chara!, Amu and Utau's most powerful forms - Amulet Diamond and Seraphic Charm - both have very large wings that enable them to fly in pretty formations. Utau's prove useful, as the feathers purify all the X-Eggs in the area.

Wings are very prominent in Sekirei, where a kiss from an Ashikabi is required to "wing" a Sekirei, granting them greater power. More a case of "wings give you power", but still a good example.
In Code Geass, the newest-generation Knightmare Frames, the Lancelot Albion and Guren SEITEN both sport glowing, angel-like wings made of green and red energy, respectively.
In Bleach, Byakuya Kuchiki manifests an aura in the shape of a pair of wings when he uses the "Final Scene, White Imperial Sword" attack of his Empathic Weapon. Toshiro Hitsugaya gets a pair of ice wings when he unleashes his bankai, and Uryu Ishida gains a single wing of light when he unleashes his ultimate power. It's later implied that an improved version of this exists for all Quincy And then there's of course Ulquiorra.
Kaoru from Zettai Karen Children gets angel wings when she faces off against one of Mio's clones combined with a bulldozer. The show's second opening theme is titled "MY WINGS", and plays up the wing symbolism further by showing the entire trio with wings.
In Shakugan no Shana, Shana sprouts flaming wings during her second fight against Margery Daw.
In the "Rescue Sasuke" arc of Naruto, Chouji uses a number of food pills during a battle to give him power boosts. The third one instantly converts all his body fat into chakra, which blaze from his back like glowing blue butterfly wings (Chouji means "butterfly"). He is later able to summon the chakra wings without taking the red pill.
Also Sasuke's Curse Seal Level Two, though instead of being angelic they're more of a cross between bat wings and webbed hands◊, and he can't fly, just glide and use them as shields.
Many MANY Shoujo related stuff. They may not always keep the wings, but the wings will always show up in their Magical Girl transformation or something. And of course, wings are decorated on their accessories, weapons, and battle outfits as well.

Nodoka of Saki, when she's channeling the Nodocchi personality that allowed her to become the top online Mahjong player, will be depicted as sprouting wings from her back.
It's probably easier to name the Digimon who don't get wings (or at least some form of flight) as they reach their highest levels of power. Though Digimon does have a bit of a trend that the more wings you have, the more powerful you are. Example; Angemon, (six wings), Magnaangemon (eight wings), and Seraphimon, (ten wings)
Setsuna's pactio card in Negima!? gives her large, beautiful white wings with which to fly around slicing the Monster of the Week. Does not apply in the main series/manga, as she (as a half-demon) has the power to pull out from the beginning but largely does just fine without them.
The Crusniks in Trinity Blood sprout wings in their more powerful forms.
Maka from Soul Eater demonstrates her new-found power (special 'Grigori' soul plus Death Scythe partner) by producing wings on Soul for them to fly with. Cute but unimpressive at first, Soul Resonance transforms them into large, angelic ones.
They were only cute and unimpressive because Maka demanded cute wings. She later grows out of that line of thinking.
It was also down to her and Soul disagreeing on the image of wings. Maka wanted 'cute angel', Soul could not imagine 'angelic' in relation to Maka, and the conflict makes them crash. The compromise resulted in the little wings they got when flying with Kim. As per usual, their mutual feeling and badassery allowed them to up the ante to fight Gopher. As with the black blood, the rather cool wings shown in that fight might well end up the norm.
Much earlier on, the result of consuming the souls collected by Nidhogg enables Crona and Ragnarok to grow wings. Kid appropriately calls them the "black dragon".
Hiro grows a pair of wings made of light while holding Excalibur.
Gopher's own grigori soul allows him to grow wings (though not physical ones) to fly, but unlike Maka's they are black which she puts down to magic, presumably Noah's influence. The fact he does not need a Weapon to use his 'soul wings' to fly may indicate Maka will be able to do the same at some point.
The Fly card in Cardcaptor Sakura initially causes wings to grow on Sakura's sealing staff, which she then can ride like a broom. But early in the Sakura Card arc, she changes the card to instead grow wings on her back, letting her fly alone and leaving the staff free to be used with the Sword card.Kero is completely astonished that she was capable of this.
Violinist of Hameln: Hamel sprouts wings while delivering the final blow to Kestra. It was the first time his angel blood showed. The wings disappear soon after.
Armitage III: The upgrade that Armitage receives at the end of the OVA plays with this, as the wings (and the subsequent mobility they provide) is half of the upgrade. Even Armitagefinds them to be a little pretentious.
"It's a little too angelic for my taste."
Katekyo Hitman Reborn!: After Byakuran finishes finishes his little Exposition about Ghost, he shows off the flames Ghost absorbed as wings.
In Saint Beast, all angels have wings, but most can't use them. Among the characters that can, however, are Rey, who gets functional wings bestowed on him at the Day of Benediction ceremony as mediated sort of power-up, and Luca an Amnesiac God, whose wings appear under duress.
In Gao Gai Gar, both J-Der and King J-Der have a utility called Plasma Wing. It basically gives the mecha 10 peacock-tailfeather-shaped wings, that allow them to travel much faster, and are fueled by raw determination. King J-Der only uses its Plasma Wings once, however, as part of its special attack, J-Phoenix, where it sets itself on fire and rams the enemy.
It can be argued that this also applies with the Genesic Machines. While both GaoGaiGar and Gao Figh Gar had wings in the form of Stealth Gao, Genesic GaoGaiGar also gets a set of wings, that are actually alive and sentient, in the form of Gadget Gao. More along the lines of Rule Of Cool, as the wings aren't big enough to lift the mech, yet it still works.
In Hyper Speed GranDoll, Hikaru's final power-up, Gran Master, comes with wings.
The Thriller Bark arc of One Piece had Robin showcasing a power where she can use her Hana Hana abilities to makes wings. The downside is that she can only stay in the air for five seconds. The wings are made of body parts after all.
Pretear, Pretear's final form White Pretear has huge translucent butterfly wings.
In a more comedic example, England from Axis Powers Hetalia grows a pair of white, feathery wings in his Britannia Angel form.

Her actual thoughts shortly after growing them? "Seriously though, what's with these wings?! They're in the way! Why did I grow them in the first place?"

In Empowered, Emp's Die or Fly-instigated uber-power-boost is accompanied by the appearance of temporary Energy Wings.
In W.I.T.C.H. the wings of the Guardians are originally this, as (differently from the animated series) they can't actually fly (and admit they have no idea why they have them when Orube asks them why they have wings). Later the New Power Mid-Season Upgrade gives them working wings.
In Neil Gaiman and Terry Pratchett's Good Omens when Crowley and Aziraphale take the side of the Antichrist in preventing The Apocalypse, they decide it's pointless hiding their wings anymore. In a subversion of the devil wings trope, Crowley also has feathered wings; after all, he may be Fallen, but he's still an Angel.
Kerry Ellison, in the Whateley Universe. Well, her codename is Seraphim, so it's not exactly a big surprise. Slightly subverted in that the first time she manifests her angelic wings she flaps around and can't fly straight until she gets used to them..
In James Swallow's Warhammer 40000 novel ''Deus Encarmine'' and ''Deus Sanguinius'', Arkio grows wings — although in this case, it also makes him look like their primarch reborn, as Sanguinius had wings. Later, after the Chaos taint that had made Arkio like that was revealed, Rafen fights the demon behind it. For a moment, while wielding the power of the Spear of Telesto, he takes on the appearance of Sanguinius, complete with wings.
In Sabbat Martyr, the eponymous Saint's reincarnation is shown charging into battle with giant, glowing, ethereal green wings.

In Accel World, Haruyuki's Avatar Silver Crow is the first Flying Avatar in the Accel World. His "basic" moves — punch and kick — are actually special moves — flying punch and flying kick.
Played with in Ninja Sentai Kakuranger and the third season of Mighty Morphin' Power Rangers, where Tsubasamaru/the Falconzord can add wings to Kakure Daishogun/the Ninja Megazord, but not Muteki Shogun/the Shogun Megazord, where it forms laser cannons instead.
The Mega Winger attaches only its large wing weapon to the Mega Voyager in Power Rangers in Space and Denji Sentai Megaranger. Usually, the two full mechs would combine, but this is not the case here.
Kamen Rider Den-O's Wing form. While the wings are only on display for a second during the transformation, the form is indeed more powerful than Ryotaro's four default forms. This trope really comes into play when Sieg attaches to Climax Form, granting Ryotaro an actual pair of wings based on his mask.
These could also be interpreted as five extra scarves, to go with the one from the Cyclone Memory.
Kamen Rider OOO has animal-themed forms, and surprise surprise, the most powerful of the basic forms is the bird-themed one. He also gets wings as part of the actual Super Mode, a dinosaur form (courtesy of the pterodactyl part of that form).
The final episode of GARO has the titular character growing wings on his armour to fight Meisha. (In a slight subversion, he then engages in a fight with an even more powerful foe after being Brought Down to Normal and holds his own perfectly well.)
Super Rescue Max in Tomica Hero Rescue Force. It's basically the same as Rescue Max, except now it has wings built into it. It's surprisingly fast and agile.
Tabletop RPG

In Xenogears, the Red Gear piloted by Id has wings of green light, with yellow feathery projections. They become more brilliant as the engine coil warms up.
The Omnigears, augmented versions of the heroes' typical Gears, all have wings.
And of course, the Xenogears itself, which is just the evolved form of Id's Red Gear.
The explanation is that the wings are really just the superheated exhaust coming from the gear.
Kefka grows six wings for his final battle: two black, leathery bat/demon wings, two darkly feathered wings that seem like a mix of demonic and angelic wings, and two white, feathery angel wings.

In other Compilation entries, Sephiroth has 1 black wing on his right, Genesis has a bigger black wing on his left, & Angeal has 2 white wings on his right.
Rinoa's "Angel Wing" Limit Break in Final Fantasy VIII, which provides her with exactly what it says and a heightened magical power.

Two decorative wings on Eiko's back grow to more realistic proportions during her Limit Break.

Angels in Tales Of Symphonia. Also renegade angels. And Colette, when she was turning into an angel. And Lloyd near the end, because he's just that much of a messiah.
Some Pokémon gain wings and the Flying type upon reaching their last evolution. Notably Charizard, Dragonite and Salamence.
Also many Bug types—Beautifly, Butterfree, Mothim, Masquerain, ect...unfortunately, aside from maybe Masquerain, none of these are particularly powerful like the examples mentioned above. Generation five did give us Larvesta, a bug who you could equate with power causing wing growth but it is not a flying type. It does learn many flying moves after evolution though.
Trapinch gains wings and the Flying type Levitation ability, because it also gains the Dragon type when it evolves into Vibrava. This is different because Vibrava is not the final form.
Similarly, Deino from Black and White gains a pair of wings upon evolving into a Zweilous. However, a Zweilous can't use its wings for flying until it becomes a Hydreigon where it has six wings and levitate as its ability.
Achaea characters have the option of transforming into a dragon on reaching level 99. Wings, talons and really bad breath included.

Yoshi's final smash in Super Smash Bros Brawl mostly revolves around him growing wings and just going nuts on the other characters. This is based off a pair of power ups from Super Mario World, one of which is called "Yoshi's Wings".

Continued in Valkyrie Profile 2 Silmeria for all three valkyries. Alicia starts doing this when her super attack upgrades. Finally, there's the one true valkyrie, who sprouts SIX wings in her version of Nibelung Valesti. One set for each vakyrie.
In Twinkle Star Sprites, Princess Sprites, Ran's powered-up older self, has pixie wings. Possibly justified, since Ran's mother Memory also has wings.
The Bad Ending of Disgaea 2 has Adell grow a pair of huge black wings after he's possessed by Overlord Xenon.
Ernst in Ys: The Ark of Napishtim grows black feathery wings. Considering his goal was to gain the power of the Winged Gods, this should hardly be surprising. Also from the same game Adol Cristin temporarily sprouts white feathered wings.
Where does Adol himself sprout wings? Don't remember that.
A minor example in Final Fantasy XI, Valaineral R Davilles has a unique AoE Weapon Skill where he temporarily grows wings of light before slamming the ground and making pillars of light come out of the ground.
World of Warcraft has a Paladin ability, Avenging Wrath, that temporarily boosts all damage and causes the user to sprout a halo and golden wings of light.
With the new expansion it now boosts damage and healing.
And let's not forget some of the armor sets that boast wings of varying levels of solidity as part of their shoulder pieces. Priests in particular seem to get this effect, although Warlocks have the best by far in a set that randomly and temporarily sprouts an enormous set of demonic bat wings.
Wildheart Spaulders, the classic dungeon 1 set of druid shoulders, had birds perched on them, their wings stretching to the sky. Big birds.
Warlocks who specialize in Demonology have a "Demon Form" they can shift into for a short time. In this form, they appear as a black goat-hooved demon ... with wings.

With the conclusion of the Cataclysm expansion, rogues who are willing to spend many hours, mountains of gold, and kill Deathwing can gain the "Fangs of the Father" daggers which, among other things, grant the rogues the ability to sprout wings after a set number of attacks. Granted said wings cannot fly, but hey, Rule Of Cool.

Inverted in Atelier Iris, where Lita occasionally sprouts wings, but only when in a greatly weakened state.

Castlevania: Dawn of Sorrow's Soma Cruz, while utilizing the soul of a flying humanoid, will sprout huge wings, twice his own size. The extent of this newfound wingspan is making him smarter and luckier.
Toyosatomimi no Miko grows butterfly wings. As a Taoist, it's only appropriate that she invoke Schrödinger's Butterfly.
Before any of them was the PC-98 boss Shinki, who grew six glowing white wings in battle that turned into more bat-like purple wings midway. Shinki is the god and creatorof a world of demons.
When Marisa Kirisame and Yuuka Kazami appeared in the Seihou series (a sort of sister series to Touhou), they both had a pair of wings. Yuuka's were green, befitting her power over flowers, while Marisa had angel wings. Fanon has generally decided that this trope applies to both of them when they're going all out — which may be supported by the games themselves: Yuuka only has wings when she's performing an attack, while Marisa in Seihou is the first boss of the Extra stage. Fanon also tends to depict Yuuka's wings as made out of leaves.
Melissa also subverts this trend: When using her rage bullet, she literally uses her wings to materialize all the massive shrapnel and energy beams, and appears without them for as long as the attack is active.
Played straight at one point in the first game. After Kalas' Face Heel Turn, he grows a second wing when he's infused with Malpercio's power. When he rejects Malpercio later, he rips the wing out of its socket.
Invoked in Arc The Lad Twilight Of The Spirits, but as a Zigzagging Trope. Kharg gains the ability to learn magic early in the game, but doesn't know why; when it's revealed later in the game that his magic is a result of his Half-Deimos lineage, the shock causes him to grow a pair of wings, which he rips from his back in disgust, so he's both a justified case and an avertion. His brother Darc is an inversion; he begins the game with wings and spellcasting abilities, but shortly after his wings are torn off, he finds a human sword and decides to incorporate human martial arts into his fighting style.
Super Robot Wars 64 has the Simurgh Splendid, created from the combination of the Simurgh and the Elblus.
In Street Fighter III: Third Strike, Gill has a screen-filling super (called "Ascencion" or "Seraphic Wing" depending on who you listen to) during which he briefly is shown with three pairs of wings. Not surprisingly, this is the most universally loathed super in the game.
Really powerful machines in Siter Skain's The Tale Of Alltynex get energy wings when using their full powers. This includes the player's ship at one point.
These games are also largely responsible for the same style of wings appearing all over the place in Fraxy, after Eboshidori made several Siter Skain-inspired bosses.

In Dantes Inferno, Dante can activate an ability called "Holy armour", which gives him invincibility and health regeneration over thirty seconds, giving him two wing-shaped beam things on his shoulder blades.
They don't do anything, really, but some theories think that either the wings themselves are what give Dante his protection from Hellspawn, or they act as vents to prevent Dante from blowing up from the sheer Holy power.
In the PSN/XBLA title Moon Diver, each of the characters gain a pair of energy wings when a special technique is used.
In Aion, we have the Daevas (who are basically angels by another name). Humans can become Daevas, gaining Immortality, wings and other nifty powers in the process.
Zone Of The Enders has Anubis, with six massive wings. In an anime spinoff, they open up to absorb projectiles into subspace and redirect them back to their enemies.
In The 2nd Runner, the wings become disembodied, held to the frame only by streams of data-like energy which is only visible when the lines flash along the frame. The also exhibit a red burst when open to contrast Jehuty's blue.
Additionally, there is a boss fight involving a weaker duplicate of Anubis that lacks the wings to further lampshade the trope.
Jehuty can also qualify as well. While the physical wings are quite small, the energy they produce is easily half the size of the frame itself when greater speed is demanded and its color changes as it evolves, going from blue for the whole of the first game, to bright green near the end of the game and white for the final battle
The anime adaptation, Dolores i features Hathor, an armless machine that does its physical fighting with the large featureless wings growing from its feet.

Webcomics
In Devil Bear, the Daivas have wings made entirely out of (infrared?) light.
The trolls themselves grow butterfly wings when they ascend to the God Tiers, as a result of their cultural ideals of physical perfection as a vaguely insectoid race. Humans have no such cultural equivalent, and so don't gain wings (but can still fly).
In Goblins, Maglubiyet the Goblin deity marks his chosen ones with wings at birth, and each is destined to become a great leader amongst the Goblins; Duv the White Terror, leader of the Viper clan, currently holds that honour.
In El Goonish Shive, the most powerful spell Nanase got is Flying Brick "angel form" giving pearly coating and two pairs of wings. In flight they at best add maneuverability, but apparently are near-unbreakable and at least the tail pair is prehensile.
In Alien Dice, Lexx gains wings after leveling up. One of them is immediately bitten off by a giant alien monster. Disappointing, but this did save him from being eaten completely.
In UC, Iku gains a pair of fairy wings, when she uses her powers in the other plane they are exploring. It’s not clear if this is her tapping into her true form, or if it is an effect of the plane.
In Dead Fantasy, Rinoa has a pair of white angel wings, to go along with her new-found levels of badass, presumably.

Optimus Primal also got wings after carrying Optimus Prime's spark for a few hours. He had to transform into a plane to use the wings, but still...The new modifications remained even after he gave the spark back to Prime.
Cheetor in his Transmetal body could count. His flight mode wings had jets on the ends of them.
On one occasion, Megatron got wings as part of a power up. They were somewhat overshadowed by him getting the ability to turn into a dragon at the time, though.
