Vire

"I'm amazed you've come so far. I thought you a harmless turtle, but I miscalculated. ...At any rate, I'll finish this soon!!!"

- Vire

Vires are uncommon winged demons that split into Keese when attacked. Their name likely comes from "vampire."

The Legend of Zelda
Vires debut in The Legend of Zelda, described by the manual as "a devil that controls the Keeses." They appear as pudgy blue demons with four eyes, first appearing in the fourth labyrinth, Snake, where they are the primary type of enemy. They commonly appear in dark rooms. They move smoothly when going up or down, but hop when they move to the side. If hit with an attack not strong enough to defeat them, they split into two red Keeses, which act the same as normal Keeses, and will respawn once the room is left. However, attacks strong enough to defeat them in one hit cause them not to respawn.

The Legend of Zelda: Link's Awakening
Vires, alternatively known as Winged Demons, appear in Turtle Rock in The Legend of Zelda: Link's Awakening, where they more actively attack Link and appear to only have two eyes. They now fly slowly towards Link from the edges of the screen, breathing pairs of fireballs at him. If he gets too close, they will quickly dart back offscreen temporarily. Once a Vire has launched several shots at Link, it will quickly swoop at him, allowing him to attack it with his sword. Alternatively, he can shoot arrows or the hookshot at it to damage it, though the latter is slow enough the Vire might fly away before being hit. Well-placed bombs can also work. Once a Vire has taken three points of damage, it splits into two skull-headed Keese that also swoop at him, but can be defeated in one hit. Once the Magic Rod is obtained, Link can use it to destroy Vires in one hit.

In The Legend of Zelda: Link's Awakening DX, Vires are colored red, while their split form has green shading. In the remake, they are again red, and the shine on top of their heads is reinterpreted as a light-colored crest.

The Legend of Zelda: Oracle of Seasons/Ages
In both The Legend of Zelda: Oracle of Seasons and Oracle of Ages, Vire appears as a miniboss working for the respective game's villain, being Onox or Veran. In the former game, he appears in the Ancient Ruins, and in the latter game, Mermaid's Cave. In both fights, he acts exactly the same, though in a linked game, he recognizes Link on the second fight. In both appearance and behavior, he is based off Vires' appearance in Link's Awakening DX, though his artwork seems to give him four squinting eyes. Additionally, a linked game features an extra appearance of Vire in the second game prior to that game's battle with him.

When his battlefield is entered, he introduces himself as the loyal henchman of the game's villain, though if he has been beaten before in a linked game he will instead be shocked in Oracle of Seasons or impressed in Oracle of Ages. He then teleports to the edge of the room and begins flying while shooting fireballs, just like the ones in Link's Awakening, albeit less cautiously about letting Link get close. At first, he only breaths dark blue fireballs which act like the ones from before, coming in pairs and moving slowly in straight lines. Once Vire is hit, he gets annoyed and begins deliberately keeping distance between him and Link, swooping away when Link gets even remotely close to him. Additionally, he retaliates with two consecutive red fireballs that home in on Link whenever he darts away. After another hit, Vire calls Link a bully and stops holding back, now moving faster, shooting the red fireballs at any time, and adding a third, orange type of fireball that splits into six. Once he is hit again, Vire tells him goodbye and splits into two red-winged, skull-faced Keese, which continue to swoop at Link. Once they are defeated, Vire re-merges and says he was overconfident, but will report Link's progress to his master. If on the second game, Vire instead bemoans failing both masters and apologizes to them before exploding.

If Oracle of Seasons is played through first, Vire has an additional appearance in Oracle of Ages, where he kidnaps Princess Zelda and takes her into the Black Tower, which Link must then climb in a side-scrolling segment based heavily off the arcade game Donkey Kong.

If Oracle of Ages is played through first instead, Vire has another appearance in Oracle of Seasons, where he appears in the Treasure Chest beneath Sunken City that normally contains the Pyramid Jewel, which he puts on a ledge in the cave that can be accessed from Sunken City.

Zelda: The Wand of Gamelon
A single Vire appears early in Zelda: The Wand of Gamelon, in the dark barn of Kobitan, a starting location. It is tall and thin with a gargoyle-like face, a green toga, and purple, cape-like wings. It simply walks back and forth, occasionally casting a magic projectile at her. Despite its sinister appearance, the Vire is defeated in just one hit, granting Zelda the key to the Hungry Girl's house.
