Ziggerastica is a small Nanodragon who believes himself to be a god. He is the king of the Nanodragons and is small in size, but powerful with his army of Nanodragons. Ziggerastica is an Emperor Beetleboog Bolderbug.
Ziggerastica appears again on the Island of Tomorrow and helps Hiccup become King of the Wilderwest by having his subjects elevate Hiccup into the air, thus making all the vikings gathered in Grimbeard's ruined castle believe Hiccup to have been chosen by the gods to be King. Ziggerastica states that he's revolting against Furious's Revolution. Ziggerastica does this because he believes that because of his size, Furious believes he can tell him what to do.
