Alvin the Treacherous

Alvin the Treacherous is chief of the Outcasts and ruler of Outcast Island. Formerly a resident of Berk, Alvin's intentions are to claim Berk as his own and retrieve Hiccup's knowledge for his own. He does not appear in the original movie, but rather the spinoff TV Show DreamWorks Dragons instead.

Physical Appearance
Like the other Outcasts, Alvin sports a large, messy black beard and hair and crooked teeth. He wears a viking helmet with a crest on the front and four dragon-horns on the side with scale-like armor covering his body. He wears gauntlets on his arms adorned with spikes and a belt held togather with bone.

Personality
As his name implies, Alvin is decietful, malicious, violent, sadistic and (of course) treacherous in his deeds. His goal is to take Berk for his own as both a lust for power and as vengeance for his banishment from Berk. He seems to take pleasure in frightening those around him (especially his number one and number two, Savage and Mildew), and shows benign disappointment when Hiccup doesn't respond to it. Being treacherous, he himself pertains a distrust of others like Dagur the Deranged. Though he is spiteful, unlike Dagur, he is also very patient, willing to turn himself in to the Hairy Hooligans if it is his only option.

It is implied that the relationship between Hiccup and Snotlout is parallel to Stoick and Alvin when they were the same age.

Powers and Abilities
Alvin is incredibly strong, equal to - if not stronger - than Stoick. He has demonstrated his strength by matching Stoick in battle, throwing a Deadly Nadder into a cage by himself and stunnig Meatlug out of action with a single punch to the face. He is shown to have an extensive knowledge of warfare and effectively leads the Outcast Tribe with a combination of intelligence, strength and fear. Alvin, like his name suggests, is very treacherous and quite clever. He is capable of creating cunning plans that have fooled Hiccup and the rest of the Dragon Riders in the past, such as when he released a force of Changewings as a distraction for Savage and Mildew to carry out the real plan. He knows right before Hiccup plan to save Stoick that Dagur has the army and won't hurt Stoick yet until he gets the Toothless. He is a very accomplished fighter and was able to hold his own against Stoick in single combat. He is also able to defend himself from wild dragons with ease, with or without weapons. However, his size can also result in a disadvantage as Dagur was able to hold off Alvin and dodge most of his attacks with his superior speed and agility. He shown for his size and weight he can jump over Stoick head. He shown that he fast enough to grab Snotlout in time for the Screaming Death to eat.

Weapons
Like all vikings, Alvin is skilled (and not relegated to) a limitless number of weapons, including swords, bludgeons, axes and so on. When he trespasses on Berk, he retrieves a small axe he left behind in his banishment. Despite this, he is easily able to

Role in the Crossover
Much like in the show, Alvin serves as a central antagonist to the Big Four, using every tactic in his arsenal to battle his enemies and usurp any force that stands against him.
