Legendary Trio

The Legendary Trio is a group of three dragons, released on the 22nd of November, 2009. They are made up of Magma, Thunder and Ice Dragons. They were started to be referred to as the Legendary Trio as TJ09 hinted on the release page about their relevance to the 3 legendary trio Pokemon birds; Moltres (Magma/Fire), Zapdos (Thunder/Electric) and Articuno (Ice). They were all dropped from the main cave as caveborns, although people quickly noticed they were dropping less than most dragons when they are first released. This, along with their title of 'Legendary', and the fact they flat out refused to breed with rares (Geodes, holiday dragons, metallics as well as themselves) suggested to many that they are the new rares in the cave. After "The Change" they were able to interbreed as well as breed with other rares thanks to the implementation of the Rare x Rare breeding. Since "The Change" they now also drop in different habitats:
 * Ice Dragon → Alpine
 * Magma Dragon → Volcano
 * Thunder Dragon → Desert

Ice Dragons are portayed as very dangerous hunters, which have such cold body temperatures that they freeze their prey solid as their murder method. Magmas are described as dragons with a great heat tolerance, which do not need to eat much to sustain themselves. Thunders are shown to collect lightning on their wings as they fly, causing a great boom of thunder whenever they clap their wings.

Both Ice and Thunder eggs use the regular cracking system, but Magmas differ. As magma eggs mature, it looks as though magma is leaking out of the shell.

Breed specific action.
As a part of the "Mod Mayhem" release on the first of April, 2010, the members of the legendary trio were given the breed specific action known as Summon, which joins their forces to summon a Guardian of Nature egg when all 3 dragons are present on a user's scroll.
