The Armor Wing is an exclusive dragon released with the Battle for the Edge expansion on December 18th, 2015. It can be purchased for 750 gems (600 for members) or awarded for finishing a certain quest.
From the How to Train Your Dragon Wiki:
- "Sitting atop its hoarded pile of looted metal on Iron Isle, the Armorwing appears at once impregnable and invincible, but appearances can be deceiving.
- With its welding torch-like flames and chain-whip tail, the Armorwing keeps enemies at bay long enough for it to attract new scraps of metal to its magnetic body and fuse them into an ever-expanding coat of armor.
- However, that armor is just a shell used for protection and intimidation. Beneath that reinforced hide lies a much different dragon that would prefer to remain in isolation with its private trove of discarded metal treasures"

- While in School of Dragons, Armor Wing is spelled as two different words; It's also spelled as a single word (Armorwing).
