Galaxy Dragons in DragonVale: How Co-op Breeding Gets You Each One

Published October 24, 2026 Updated October 25, 2026 3 min read

The short answer: Galaxy dragons are a special class of Epics that — with three exceptions — can only be bred in the Cooperative Breeding Cave, at very low odds. Every player receives one free Galaxy dragon on reaching the required level. The exceptions are Solis, Lunis and Rigel.

This guide lists the family, explains how the free dragon is assigned, and gives a realistic plan for collecting more.

About the Galaxy dragons

Galaxy dragons launched on 5 May 2015 alongside co-op breeding. They were added to the Market in waves: Antarian, Arcturian, Bizurian, Polarian and Sorarian in July 2015; Andromedan, Procyon, Eridanian and Comet in November 2015; Nebula, Rayleian, Celerulean and Teidian on 4 May 2016.

The family

The wiki lists these Galaxy dragons:

Antarian, Sorarian, Polarian, Arcturian, Bizurian, Andromedan, Procyon, Comet, Eridanian, Nebula, Teidian, Celerulean, Rayleian, Nova, Singularity, Starlight, Glimmerwing, Rigel, Gravity and Lambovian — plus the Epic hybrids Solarflare, Solis and Lunis.

The three you can breed in your own caves

Dragon	Recipe	Time	Level
Lunis	Moon Dragon + any Galaxy-element dragon	24h	21
Solis	Sun Dragon + any Galaxy-element dragon	24h	21
Rigel	Galaxy parents contributing Galaxy and Rift, bred in the Rift Breeding Cave, with every other Galaxy dragon owned	16h	28

Step-by-step plan

Reach the level that unlocks Galaxy dragons and claim your free one.
Add active friends and set a useful featured dragon.
Use the Cooperative Breeding Cave every time it is free.
Level your Galaxy dragon to 4+ and use it with a Moon or Sun Dragon for Lunis and Solis.
Only plan for Rigel once you are close to owning all the others.

Which free dragon do you get?

The free Galaxy dragon depends partly on how recently your park was active. For example, the wiki records that new players in the first distribution received a Bizurian, while parks opened within the previous 30 days could receive an Antarian or Polarian (48% each) or an Arcturian (4%). Later sets used other mixes.

Rigel: the hardest dragon in the family

Rigel needs level 28, can only be bred in the Rift Breeding Cave, requires both parents to contribute the Galaxy and Rift elements, and only becomes possible once your park contains all 22 other Galaxy dragons. It has also been sold — 6,028 gems in the Market, and 7,500–10,000 in events. Our Rift guide explains the Rift.

A realistic collecting plan

Claim your free Galaxy dragon and level it to 4+.
Use it immediately with a Moon Dragon for Lunis or a Sun Dragon for Solis — the only two you can work on in your own caves.
Breed in the Cooperative cave daily; each Galaxy dragon there is a low-odds roll, so volume matters.
Track which Galaxy dragons you own in the in-game Dragonarium.
Consider the Market for specific Galaxy dragons that have been added there.

Quick checklist

☐ Free Galaxy dragon claimed
☐ Friends added and featured dragon set
☐ Moon or Sun Dragon ready for Lunis/Solis
☐ Co-op cave used daily

Common mistakes

Trying to breed most Galaxy dragons in normal caves. Only Solis, Lunis and Rigel work outside co-op.
Ignoring your featured dragon. It determines what friends can breed with you.
Chasing Rigel early. It needs every other Galaxy dragon.
