Thunder Dragon

Thunder Dragons were released on November 22, 2009, alongside Ice and Magma Dragons.

If users have one of each of these dragons, collectively known as the Legendary Trio, then the dragons have a Breed Specific Action called Summon. This BSA allows one to use the dragon's united forces to attempt to summon a Guardian of Nature egg. The more trio sets a user has on their scroll, the more likely a summoning attempt will be successful.

Egg
"Whenever you go near this egg, your hair stands on end."

Hatchling
"Aww... It's a cute baby dragon. It seems be allergic to something, and every time it sneezes, sparks shoot from its nose and mouth."

Mature hatchling
"Aww... It's a cute baby dragon. It seems be allergic to something, and every time it sneezes, sparks shoot from its nose and mouth. And look! It's grown its wings! It must be close to maturing. Small bolts of electricity occasionally fly off of it, zapping nearby objects."

Adult
"Thunder dragons are the masters of electricity. Their wings gather energy as they soar through the clouds, and when they clap their wings together they can create devastating arcs of lightning. They can stay airborne nearly indefinitely, landing only to sleep and breed; they catch their prey from the air and take moisture from the clouds. A Thunder dragon's roar is considered to be an omen of misfortune."
