Greygnarl is a boss and character in Dragon Quest IX. Known as the Hero of the Heavens, he is a dragon that lives high atop Upover at the summit of the Magmaroo volcano.
Three hundred years before the events of Dragon Quest IX, Greygnarl helped bring about the fall of the Gittish Empire by defeating the black dragon Barbarus. When the Hero reaches the summit of Magmaroo to seek assistance from Greygnarl, the dragon mistakenly believes the hero to be a Gittish warrior come to slay him and attacks them. Greygnarl sacrifices himself to stop the attack by Barbarus targeting the village of Upover.
This famed dragon of light did battle with the darkness in ancient times, earning the moniker 'hero of the skies'. These days he likes to take the shape of an old man and while away the hours in happy idleness.
Greygnarl appears as a S-rank member of the Dragon family as part of the original Dragon Quest IX event, appearing on his own banner alongside Axolhotl. He can participate in Stella's Battle Road as a party member. As of the most recent update in the Japanese version, he can be recruited from any banner, including the Regular SP Scout.

The war between Greygnarl and Barbarus seems to be originate from a legend about Heilong River (River of Black Dragon); however, the colour of evil and good dragons have been switched.
The name "Greygnarl" indicates his colour, as well as his age.
If you look carefully at Greygnarl in Joker 2, someone wearing the Dragon Warrior armour is riding him. It is most likely a reference to the Hero of Dragon Quest IX.
It should be noted that before Greygnarl is fought as a grotto boss he mentions something about "Styrmling" being the third dragon (the first two being himself and Barbarus). This could possibly be similar to "Stellestria" where as the conductor had a past life as something different.
