History Main / PowerGlows

* Any ''VideoGame/SonicTheHedgehog'' character with a [[SuperMode super form]] when in said form.

** Some incarnations of [[Characters/GodzillaTheGhidorahs King Ghidorah]] have this. The Heisei and Showa incarnations have light-up ''horns'' in ''Godzilla: Destroy All Monsters Melee'' and ''Godzilla: Save the Earth''. With the [[Characters/MonsterVerseKingGhidorah MonsterVerse incarnation]], his three necks glow with light while hcharging up their [[BreathWeapon Gravity Beams]] (think [[Film/TheHobbitTheDesolationOfSmaug Smaug]] but with lightning instead of fire), and it fits with how Godzilla and Mothra also light up in various ways when charging their built-in energy weapons.

* Then there's the ultimate attacks of the titular SuperRobot in ''Anime/GaoGaiGar'': [[YinYangBomb Hell and Heaven]] has one fist glowing red and the other glowing yellow, while using the [[DropTheHammer Goldion Hammer]] results in the entire robot glowing gold. In the OVA ''FINAL'', they introduce [[spoiler: the world's biggest ban hammer that has a head several magnitudes larger than the handle and is made up of nothing but pure, glowing energy]].

* ''Literature/{{Tempest}}'': Merpeople and selkies have natural tattoos on their backs and shoulders that give off a phosphorescent glow deep underwater, but also sometimes glow when a person uses magic.

** Later games in the series, such as ''VideoGame/MegaManBattleNetwork4'', implement [[{{Synchronization}} Full Synchro]] as an effect you can get in battle if you're skilled. It's depicted by Rock glowing (his color becomes light) and a pink halo spinning about his body. Very powerful [=NPCs=] and enemies in cutscenes also flash with light, notably Gospel in ''VideoGame/MegaManBattleNetwork2'', Proto (Alpha) in the ''VideoGame/MegaManBattleNetwork3'' and the Cyber Beasts in ''VideoGame/MegaManBattleNetwork6''.

** Because they're ''illuminated texts!'' [[JustForPun Ha!]]

* In TheCosmere, "Live Investiture" that is being unused tends to glow a bright white, to wit:

* ''LetsPlay/EmpiresSMP Season 2'': Magical items and beings emit differently-coloured glows, but the glow is only visible to a certain few with supernatural AuraVision abilities.

* TabletopGame/{{Pokémon}}: Holographic cards are generally considered to be powerful, or at least rarer than their non-holographic counterparts.

* ''Anime/{{Pokemon}}'':

** Within the [[TabletopGame/{{Pokemon}} TCG]], Holographic cards are generally considered to be powerful, or at least rarer than their non-holographic counterparts.

** ''Series/KamenRiderFaiz'' had an interesting spin on it: The five Riders' costumes were covered with "veins" through which pumped a glowing substance that to powered them. In nighttime scenes, the "veins" and visors would glow, and use of a FinishingMove would cause a bead of energy to run from the belt (the main power source) to the Rider's foot or sword or whatever they were going to use. The same series started a trend of a Rider's eyes glowing for a bit after they were done transforming, in order to signify that the process was done.

* In ''Series/BabylonFive'' when Delenn and the White Stars take on the Drakh, the Drakh weapons systems glow brighter and brighter to build up the tension as they prepare to fire.

* Deconstructed and PlayedForDrama in Jessica Amanda Salmonson's ''The Golden Naginata'': Unless it has been [[AppliedPhlebotinum used]] to [[UnholyHolySword wound]] the ''[[{{Unicorn}} kirin]]'' who guards it within the past month, the [[BladeOnAStick titular weapon's]] glow is so bright that it blinds anyone who sees it.

* In Literature/TheTrialsOfApollo, this is revealed to be an ability Will Solace has as a son of Apollo. To the point where [[FrogMen the Troglodytes]] make him [[LampshadeWearing wear a lampshade as a hat]].
