Every dragon in Dragon City is assigned a rarity. Some are rarer or more powerful than others.

Mythical dragons are rarer and more powerful than Legendary dragons but weaker than Heroic dragons. Some Mythical dragons already existed in Dragon City as Legendary dragons with a special Mythical badge. Now, these Mythical dragons, and new Mythical dragons, have their own rarity, along with their own Orbs, Joker Orbs, and Trade Essences.
