Undead Dragon

Undead Dragons, also known as Zombies, are a special breed of dragon only obtainable via a creation process on Halloween (October 31st), as well as being an original species of Dragon Cave. Attempting to revive a deceased dragon or hatchling on this date (either killed or purposely allowed to die) has a slim chance of resulting in an Undead dragon- they can no longer be obtained on any other day of the year. Undeads cannot breed and have been subject to controversy due to the death of dragons required to create them. They are only visible on scrolls between 12AM - 6AM (EST); at all other times, they take the form of a tombstone sprite.

In the past, Undead Dragons could be made during any time of the year, with a rumoured 1 in 100 chance of success. A few examples include two owned by TJ09 (Qemrao Thuwed and 0eidw Qemrao Thuwed), and one hatchling created in 2007 on a hidden scroll with an inappropriate code. There have also been reports of others, but the forum topic once used to discuss them has since been deleted. It is unknown when the circumstances of being able to create Undeads on Halloween only began, but rumours still continued that creation all-year long was possible; these subsequent rumours were proven false in the IRC on the 22nd of December, 2012.

The chances of successfully creating an Undead on October 31st is rumoured to be somewhere between 1 in 2 to 1 in 6. The dragon is not required to die on the 31st of October to become Undead; they can die or be killed within 14 days before Halloween, but they must be revived on the 31st. There are three potential outcomes of the revive action: reviving a normal dragon, reviving an Undead dragon, or permanent death. In order to obtain the different stages of Undead hatchlings, the dragon must be in that particular stage when it dies or is killed; Undeads cannot grow up themselves, and the dragons are automatically frozen upon death.

All dragon breeds can be zombified, even DC drakes, Vampires, pygmies and two-headed dragons (despite unique sizes or features of these breeds, all Undead dragons look the same). Unbreedables such as Papers and Cheeses can become Undead dragons, albeit ungendered. Dinos cannot become Undead due to the lack of a revive option for them. Undead "Limited Breed" dragons, such as CB Holiday dragons or Guardians of Nature, still count as their original breed and prevent players from reclaiming replacements.

Undeads used to permanently take up the kill slots used to create them. This was an unintended occurrence, and since October 2011, zombie-held kill slots have been released. Currently, any kill slot used to create an Undead will return after 2 weeks, exactly the same as a kill slot used for any other purpose. At one point, Undead dragons could not be removed from scrolls. This has changed with the Soulpeace Dragon and its Expunge BSA.

Undead dragons used to only be visible on scrolls between 12AM and 6AM DC time (EST), but now are always visible in the form of a tombstone. There used to be a glitch that caused Undead Dragons to "roam" on scrolls, despite being repositioned or re-sorted; this has since been fixed after the addition of new tombstone sprites. Undead dragons are now visible on sorting pages as well as scrolls.

These dragons are often confused with Neglected and Vampire Dragons. When using Breed sort on a scroll, these dragons actually sort as whatever their original breed was before being turned Undead.

Hatchling
"It's an undead baby dragon, produced by a failed magical spell. It probably would be cute if it weren't partially decayed."

Mature Hatchling
"It's an undead baby dragon, produced by a failed magical spell. It probably would be cute if it weren't partially decayed. And look! It somehow managed to grow wings despite being dead."

Adult
"Failed attempts to experiment with magic often result in transforming dragons into these hellish creatures. They are extremely dangerous, and will mindlessly kill any living creature without regard to friend or foe."
