Bandit

Bandit is the name of the Armorwing that Hiccup Horrendous Haddock III, Astrid Hofferson and Snotlout Jorgenson encountered at Iron Isle.

Encounter with Snotlout, Hiccup, and Astrid
"Vikings, hide your weapons! This Armorwing won't stop until it builds the perfect armor with the best metals it can find."

This dragon can be seen in the episode "Snotlout Gets the Axe". His body is covered with various metal objects molded together that he found or stole himself. One of which was the Jorgenson ceremonial axe. He needs them to cover his non-scaled body in order to defend himself.

In desperation to get his family's axe back, Snotlout convinces Hiccup and Astrid to lure a small herd of Smothering Smokebreaths to the island to yank the axe off of Bandit's back. While the plan worked, the Smokebreaths continued to attack Bandit and pulled off more of his armor, which left him vulnerable. The Dragon Riders manage to chase the Smokebreaths away and give Bandit some metal to repair his armor.

Personality
Based on the events in "Snotlout Gets the Axe", Bandit is very protective of his metal on himself and in his stash. He was very dangerous for Hiccup, Astrid, and Snotlout. All this though, is because he needs metal to be welded to his body like all Armorwings because of the lack of scales.

Physical Appearance
Bandit looks like any other Armorwing. He has underneath his metal armor, pink skin with no scales. His body shape is like that of any other Armorwing, so like that of a Boneknapper.

Trivia

 * The storyline for Battle for the Edge expansion pack in School of Dragons hints that the Armorwing that the player trains is Bandit.
