Jadedramon is a Light Dragon Digimon based on a the overall designs of the dragons in Fire and Ice and a real world Aurora. It is a little known Super Ultimate Digimon only recently discovered. It's power is said to be around that of Brondramon and Cobaldramon yet it's relation to them is currently unknown. It's wings has constellation-like lines that depict Brondramon, Cobaldramon, and Jadedramon. It's as if the markings are foreshadowing some great event... The Digicode on it's back read:

"Long ago... Fortold a legend... The Great Aurora... King of Bronze and Cobalt... Jadedramon."

Digimon World: Jade Version
The Jadedramon featured in the storyline is actually more commonly seen in it's X-Antibody version, which is the Jadedramon that is fought as the final boss. During the end of the storyline Brondramon X and Cobaldramon X go on an absolute rampage, only for them to be destroyed single handedly by Jadedramon X. Afterwards Jadedramon X needs to be defeated. The end of Jade Version is indeed a boss rush like the end of B/C, but features all three Light Dragons as the final bosses, faced one at a time with Jadedramon being last.
