Snow Owl
The Snow Owl is one of the best of Ana's skins, taking literally one of her many nicknames. This legendary skin was available through loot boxes during the Winter Wonderland events.

Overwatch developers always pay attention to the smallest details. The thing that really makes this skin pop is the amazing color coordination. The white feathers are accentuated with light blue, while her icy-blue eyes gaze deep into the soul of her enemy. The Snow Owl is definitely the best skin for winter play and even offers camouflage in snowy maps.
Captain Amari
As an original Overwatch member, the Captain Amari skin depicts Ana Amari in her younger years, before she lost an eye.

This skin features Ana in mostly blue, with highlighted white accents surrounding her cape. Her black hair is held mostly back by her blue beret, with a small sliver of bangs over her eye. The Captain Amari skin shows us what the Overwatch agents would wear during the Omnic Crisis.
Special shout-out, as well, to Horus, a Captain Amari re-skin that helps Ana blend in better on certain sand-colored maps in Overwatch.
Shrike
As the only skin costing 250 gold, this is one of the more popular Ana skins in Overwatch. Despite the inexpensive nature of the skin, it still is cool and fun skin.

This version of Captain Amari offers a dark contrast to Ana's normally bubbly nature, which is accentuated by the bright neon of her mask and cape. Even though this is only 250 gold, the Shrike remains one of the best Ana skins in Overwatch.
Ghoul
As one of the original heroes in Overwatch, Ana has a number of solid epic skin options. One of the coolest is the Ghoul skin, which was released as a part of the Halloween terror event.

The Overwatch developers created this amazing skin that glows in the dark, with her eye peering at you through the shadows, striking fear into her enemies. During the Halloween season, this is one of the best skins in the game. The mostly black skin especially pops, as it is accented with the bright orange of her creepy smile and the orange lining of her cape.
Sniper
Ana's Sniper skin gives us a hint at what Ana Amari would have looked like as a member of the military in Egypt. Though the weapon does seem more fitting on a damage dealer like Widow, this skin suggests Ana wasn't always the caring healer of the Overwatch game.

The best part about the Sniper is that this skin can be used as camouflage with a lot of sand-colored maps in Overwatch. Not only are the intricacies of this skin awesome, but they also can help you win games.
Cabana
Forced out of retirement in the Overwatch universe, the Cabana Ana skin gives us a look into what Ana was up to before she got back into the fight.

A Summer Games event skin, the Cabana skin shows what this white-haired sniper would look like when she is relaxing on a sunny beach. The blue, tan, and gold color scheme continues Ana's look, with her sleep dart especially popping out on her wrist. This skin looks especially good with the golden gun, an unlockable version of the weapon only available from Competitive points in the original Overwatch game.
Corsair
Ana already has an eye patch, so creating an Ana pirate skin should be an obvious choice for the Overwatch developers. It's no wonder Ana would choose to be a Pirate during the Halloween Terror event.

The beauty is in the details with this skin, taking Ana out of the Overwatch universe and into a pirate ship. From the bird on her shoulder to Ana's gun made of wood, and even the small patch on her burgundy slacks, this is one immersive Ana skin!
Tal
If you thought Ana's Ghoul skin was creepy, then take a look at the Tal. This was one of the Lunar New Year skins, and it is inspired by Korean culture.

One of the more colorful of Ana skins, the Tal features a smiling gold and red mask, a blue, white, and red cape, with a colorful yellow biotic grenade bringing a focus point. Despite its terrifying appearance, this is still one of the best Ana skins in the game.
Merciful
Though not one of the legendary skins, this Epic skin still represents the best of Ana Amari. This is a perfect skin to wear on a snowy map and was available from loot boxes all year round.

The white and red remind you of the red cross, which is a perfect representation of this support hero, leaning on her healing capabilities on the battlefield to protect her teammates. Donning this outfit will only inspire faith in your teammates, though worn on the wrong map, and this bright white will make you poke out to enemies.
Bastet
Originally from Egypt, the Bastet skin pays homage to Ana's home country with a sleek skin design. Only available through a challenge event, this skin is no longer available.

Legend has it that Ana became a Batman-style vigilante after Overwatch dissolved, becoming a local hero in the streets of Cairo. She took inspiration from the Bastet, the Egyptian goddess of protection and health. How the Overwatch team rated this awesome skin as Epic instead of legendary is another story altogether.
