This creature, is the single most terrible thing ever known to live on the Material Plane of existence. It is 50 feet tall and 70 feet long! It was created by the Primordials to help them during the Dawn War. Only one was created which sleeps at the world's core. There is no known way to defeat this being if it awakes so the only option the world has; is to put it back to sleep if something or someone attempts to wake it up.

1. Tiamat

Gargantuan Fiend

The Dragon Goddess of Greed, Queen of Evil Dragons, all time enemy of Bahamut and servant of Asmodeus, the great Tiamat. She has a head of each main chromatic dragon type, which is able to cooperate, and fight together. She is a hateful and greedy dragon. She has her own adventure module as well in the fifth edition of Dungeons & Dragons, I think it’s safe to say Tiamat is a foe to be reckoned with in battle.
