Description

This loathsome Ancient Supreme Dragon is the epitome of not just cruelty, impatiency and absolute evilness, but also the inner power of all dragons. It is one of the most unfathomable monsters, the force of natureHeadache inducing tyrant that has ruled its fetid domain for over Duotrigintillion years, and its very presence is Confusing.

It's size is indeed real, with gargantuan size. Just over 500 feet long from head to waist. It's wingspan is really big and disgusting. Its sheer bulk is barely enough to exist. Its scales are the color of so disturbing that it cannot be described with words. The scales are muddy, moody, and incredibly not durable, acting like plates of ancient, organic antiarmor.

Head of this Supreme Dragon is weird, It's skull is weak and can barely function, the eyes most likely dont function, and hatred and greed is all over this body.

The cruel personality of this Tyrant is easy to understate, super vain, sadistic, and immensely cruel of profound malice that enjoys the suffering of any being. It doesn't just being kinda Highly territorial and possessive, this creature views everything within its domain as its property, even living beings.

Hovewer, in reality this creature can barely survive a single day, It's natural prey are bugs, for example Beetles and Butterflies easily eradicate Ancient Supreme Dragons, not to mention Apidaes or even mamals. Tiny baby Caterpillars enjoy defeating these monsters. Flies often tackle those Dragons to OHKO them.

Exotic doom - The dragon slips on a banana peel, causing every dragon in existence to get eradicated.
