Dragons (Japanese: ドラゴン, Doragon, lit. "European dragon") are the strongest family of monsters in Xenoblade Chronicles. They possess a lot of power, and can be very difficult to defeat. Dragons are similar and may be related to Sauros.
There are only three dragons in Xenoblade Chronicles. They are as follows:
The second one, Demon King Dragonia, is a quest exclusive enemy; level 99. It is found during a Colony 6 quest, Defend Colony 6 - Demon which is triggered by having 90% of Colony 6 restored. If Dragonia is defeated, it cannot be fought again until the next playthrough. It is the only enemy to possess a slotted Ledios Arms, which is the best Heavy Armour arm in the game. The only way to get multiple Ledios Arms is to steal and refrain from killing it.
The final dragon is a Superboss called Avalanche Abaasy, and is the strongest monster in the whole game. It is found at Three Sage Summit, which is in Valak Mountain, during a blizzard and is level 120. Be prepared with Debuff Resist gems.
