Dragon Cave Wiki

Sinomorphs were released on May 21, 2017, alongside Zyumorphs as part of Dragon Cave's 11th birthday celebration. They do not possess egg or hatchling forms, and adults must be summoned via a Breed Specific Action available after collecting a set of six different Zyumorph adults (not to be confused with the Summon BSA related to Guardians of Nature).

It is possible to have multiple Sinomorph dragons, though only one can be summoned per set of Zyumorphs. If a full set of adult Zyumorphs is available, the option to "Summon" will appear on the actions pages of any unused Zyumorphs. Once selected, the dragon whose action was chosen, as well as one of each remaining color, will be displayed on the action screen.[fn 1] Any group of 6 that have already summoned a Sinomorph will have the BSA disabled on their Actions page, as opposed to the BSA not being present on the Actions page. Summoning is always successful,[1] and the gender of the summoned Sinomorph is influenced by the genders of the Zyumorphs performing the summoning.[2]

Because of the unique way in which a Sinomorph is acquired, these dragons do not have stats for views, unique views, or clicks. Its "Grew Up On" date is the date it was summoned. Breeding Sinomorphs produces either their partner's breed of egg or a random variant of Zyumorph eggs.

Official descriptions[]


Far and away one of the most enigmatic of dragon breeds, the Sinomorph is shrouded in near-complete mystery. While the exact conditions that herald its arrival are not certain, it is said to only appear when called upon by all six Zyumorphs. Record of its existence may be limited to folklore and ancient legends, but recent sightings seem to suggest this storybook behemoth may truly walk the lands of Valkemare. If the stories of the past are to be trusted, its appearance serves as a beacon of light in the face of looming calamity.

There are no notes available for this breed. Check back later; new information will be added periodically.


  • Before release, there was a change from this breed's name "Synomorph" to "Sinomorph" which was suspected to be a typo.[3]
  • When sorted by "Breed", this dragon sorts as "Sinomorph". If still using the old Legacy Breed Name Sort, these dragons sort as "Megazord", between Magnesium Amphiptere and Melismor Dragons on a user's scroll.

Additional information[]

Zyumorphs don't create a Sinormorph, they call upon one which already exists, essentially awakening a dormant force in times of peril. For that reason, it is an adult when Summoned.

  • Regarding the breed's name:
IIRC, I proposed "synomorph" (using the prefix "syn-" for the dragon i.e. "together") and that's what PieMaster counter-proposed.

  1. The additional Zyumorphs used to summon are automatically selected by age, meaning the oldest available Zyumorph of each color will be selected. The exact Zyumorphs that will be used in the summoning are shown on the summon action page.
