Angelic Beauty

We all know angels run the gamut from being light-based Eldritch Abominations to the basically human, and the human flavor are divinely hot. This rule is almost without exception.

You could almost describe them as an... Angelic Beauty.

Compare Horny Devils, for this trope's infernal counterpart (which may be literal, in some cases). Their boss(es) may also be (a) Hot God(s) as well. Also compare Beauty Equals Goodness, which fits this (almost) perfectly. See also But Your Wings Are Beautiful. Not related to Lovely Angels.

Examples of Angelic Beauty include:

Advertising

An ad campaign for Lynx deodorant used the tagline "angels will fall", and showed hot female angels plunging from Heaven to Earth to be near the guy spraying on Lynx. Axe ran a similar campaign in the US.
The Victoria's Secret Angels

Saint Beast features a cast full of beautiful man-angels.
In Ah! My Goddess, every Goddess (who are themselves Hot Gods) has a very hot and barely-dressed angel to assist them with supernatural stuff.
Most of the angels of Neon Genesis Evangelion are of the Eldritch Abomination variety, but White-Haired Pretty Boy Kaworu fits this.
Dark and Krad of D.N.Angel.
Puella Magi Madoka Magica: The eponymous character post-ascension.
Saki: Nodoka's virtual form.
AIR: Kannabi-no-Mikoto. Misuzu who is the current incarnation of Kanna is often depicted this way outside the anime.
Digimon somewhat subverts this with the likes of Angemon and Angewomon (and their Digivolutions MagnaAngemon, Seraphimon, Dominimon, and Ophanimon). It can be inferred that they play this trope straight, but they're both clad in helmets that completely cover their faces (a glimpse of their faces can also be seen during Digivolutions). It's for similar reasons that it's unknown if their Evil Counterparts Devimon and LadyDevimon (the latter of whom appears to be a White-Haired Pretty Girl) adhere to Evil Is Sexy.
Nadeshiko Kinomoto in Cardcaptor Sakura...and that was before she died and transformed into an angel in Heaven. (Lampshaded by her husband when they first met.)
Ash and Angela from Black Butler, who turn out to be respectively the male and female alternate forms of the same Fallen Angel.

The final ghost of Ghosts of Girlfriends Past appears as an incredibly beautiful angel.
The titular Angel from 1987's Date with an Angel (played by the then-luminously beautiful Emmanuelle Béart).

Ambassador Kosh in Babylon 5, and other Vorlons apparently, although those are more Fallen Angels.
- Mind you, this is All According to Plan on the Vorlons' part. They've manipulated the younger races for aeons, genetically and psychically, to always see them as beautiful divine beings. Every person who sees them sees his own image of celestial perfection.
  - Also, in a later season, we are shown this is not the Vorlon's true form, or that the Vorlons need to do something to make the other races see them as divine.
Several examples in Supernatural: Castiel is this to many fans; Michael, in the form of Michael Cohen and Jake Abel; Anna from Season 4 and 5; Season 6 briefly introduced another female angel named Rachel. Averted with Zachariah. These may not count as this trope however. They use hosts, so technically the fanbase is finding the human hosts pretty, not the actual angels. The only angel whose celestial form is explicitly described in-story as "beautiful" is Lucifer. The angels themselves are actually of the Eldritch Abomination variety, but the show has never shown their true forms.

Angels in Lamb take the form of ridiculously attractive blondes. The main angel, Raziel, is sufficiently handsome enough to regularly fluster Biff despite Biff's insistent heterosexuality and Raziel's infuriating stupidity.

A number of angel pictures on Magic: The Gathering cards fit this, with the first Serra Angel picture (up to 4th edition) just being a mild one.
Half-celestial races in Dungeons & Dragons, currently known as devas, are known to have an otherworldly beauty.
- For related reasons, Aasimars (those with a celestial being in their ancestry) are also frequently quite beautiful.
While most demons in Demon: The Fallen drive mortals who witness their true forms insane with horror, the few who still have low Torment do so with the angelic beauty they retained since the Days of Creation.

Kyra, the Angel of Light, from the mythology of Septerra Core.
Most angels of the Disgaea universe, most prominently Archangel Flonne and Vulcanus(?).
Any time a being of angelic origins shows up in the Neverwinter Nights modding community, she will be in possession of Angelic Beauty. Evanine in Tales of Arterra, Anera in Shadowlords, Melissa in Trials of the Academy, any others I haven't mentioned yet...
Pokémon: Gardevoir apparantly has a huge fanbase because of its/"her" feminine appearance. According to Word of God, it/"she" is supposed to resemble an angel.
The Shin Megami Tensei series largely averts this. The root-standard "Angel" is a young winged woman... covered in bondage straps, including one over her eyes; it's actually pretty creepy. After that, angels come in two categories: harsh, masculine warrior, or Humanoid Abomination (in other words, close to the Biblical depiction). The only angels that could be described as pretty are Gabriel and Lucifer's angelic form (the one Persona 3 FES dubbed "Helel").
While not exactly an angel (more like a member of the Heron, a Winged Humanoid race), Leanne from Fire Emblem Tellius fits in nicely. Her older brother Reyson is a Rare Male Example.
The Violated Hero series has Tides in the first game and Ariel in the fifth.
