Not to be confused with Etherian Wyvern.

The Wyvern is a large Hardmode enemy that spawns in Space. They resemble Chinese dragons, are long and white, and follow the Worm AI. The Arch Wyvern is the bronze-colored Old-gen console and 3DS -exclusive variant.

They will follow descending players down to ground level and can fly through blocks, but regular Wyverns tend not to fly below ground.

Wyverns will only spawn when the player is above a certain altitude (see Space § Notes) and is outside of Dungeon biome. Wyverns will not spawn during events, and having at least one NPC near the player will also prevent them from spawning. A Wyvern will not spawn if another one is already alive, and like most enemies able to pass through blocks, it will not be able to spawn if the player themselves stays in front of safe walls, even if there are valid spawn points for the Wyvern.

Segments

The Wyvern consists of 15 segments in total. The first segment is the head, the third and seventh are the legs, the second, fourth through sixth, and eighth through twelfth are body segments, and the last three are the tail segments.

Notes

It is possible to kill a Wyvern while its head is off the map. As the head is the part dropping the loot, this can result in the loss of the loot.
Despite dwelling in the sky, they are immune to lava and can swim through it unhindered, like all worm-like enemies.
On the Nintendo 3DS version, Wyverns do not despawn when all players die, unlike most other enemies and bosses.
The Wyvern will not follow the player underground. It will go in the opposite direction if the player goes below the surface.

Tips

As with any multi-segmented enemy, piercing and explosive weapons can strike multiple segments at once, dealing several times their normal damage.
- Using a bow or repeater with Jester's Arrows or Holy Arrows is a good way to kill a Wyvern.
- As of 1.4.0.1(Desktop, Console and Mobile versions), thrown-type flails like the Blue Moon or Sunfury are highly effective against Wyverns and can kill them in a single, well-aimed hit in Normal mode. The Sunfury can inflict On Fire! to multiple segments, dealing large damage with few hits.
- Other useful items for killing Wyverns and other worms are the Shotgun or Onyx Blaster(Desktop, Console and Mobile versions) (with Exploding Bullets), the Nimbus Rod, and the Medusa Head(Desktop, Console and Mobile versions).
- The Life Drain(Desktop, Console and Mobile versions), obtained from Crimson Mimics(Desktop, Console and Mobile versions), is also a very powerful choice, as it can absorb life from many segments at once.
Dodging a Wyvern is crucial, as it is capable of inflicting significant damage.
- It is easier to fight a Wyvern at higher altitudes in Space, as the low gravity helps to dodge its attacks.
  - Engaging a Wyvern with a Gravitation Potion in Space and allowing themselves to free-fall while moving horizontally can put the player at almost the same speed as the Wyvern. With adequate movement speed buffs it is possible to match or even outpace it, and while the Wyvern is tailing the player, attacking it with piercing weapons such as the Golden Shower can make short work of it, even in Expert Mode(Desktop, Console and Mobile versions) or Master Mode(Desktop, Console and Mobile versions).
Wyverns can be hard to kill in early Hardmode, so it is recommended to stay away from them until better armor and piercing weapons can be obtained.
Minecarts and the Unicorn Mount are both faster than a Wyvern.
The head of a Wyvern has lower defense than its tail or body segments, making it more vulnerable to damage as it charges the player. However, the head also deals twice the damage as the rest of the body on contact, making it risky to face a Wyvern head-on.
Because the effect of Water Candles is greatly boosted at high altitudes, placing one nearby can make farming for Souls of Flight much faster.
- On top of this, Water Candles grant an additional spawn attempt to Wyverns that nearly doubles their spawn chance.^[1]

Trivia

Although the name wyvern refers to a type of Western dragon depicted as having two wings and two hind legs, and no arms or forelegs, Terrarian Wyverns are based on the Chinese dragon, loong, or "lóng" (Chinese: 龙 / 龍), which are depicted as having no wings and four legs.
The Angler mentions in a quest that Wyverns are born and raised as tadpoles called Wyverntails.
Wyverns take knockback, while Arch Wyverns do not.
The Wyvern strongly resembles Haku's dragon form from the 2001 Japanese animated coming-of-age fantasy film Spirited Away (image).
According to the Collector's Edition trading card, Wyverns are capable of speaking and were once kind, but the Corruption has made them aggressive.
(Desktop, Console and Mobile versions) Once Hardmode begins, a Wyvern can sometimes be seen flying in the background as ambiance.
- A cloud in the shape of a Wyvern can also appear in the background.
The painting Sky Guardian, sold by the Painter, depicts a Wyvern.
According to their Bestiary entry, the Phantasm Dragons(Desktop, Console and Mobile versions) are souls of Wyverns summoned with powerful magic.

The Bestiary entry for the Wyvern: "A colossal dragon-like creature unleashed along with the ancient spirits. It rules the skies with its unrivaled might."
