Speedy is a male adolescent Speed Stinger that was befriended by Hiccup in The Next Big Sting after the riders found him injured. He was given his name by Tuffnut when the Viking was trying to get the young dragon to paralyze Ruffnut again.
Speedy appears very similar to other members of his kind, except the Alpha. He is lime green with a tan underbelly. He also has lime green fins and stubby wings. Like other members of his species, his stinger is red in color.
Speedy was, at first, very skittish and vicious, attacking the riders when they tried to help him. However, later on, he became very protective of the riders, who, at this point, he considered his pack. He defended them from the other Speed Stingers from his pack, even going as far as directly disobeying his alpha. He even wanted to stay behind with the riders, but Hiccup convinced him to return to his pack.
He is also playful and affectionate as he licked Snotlout's face, much to Snotlout's disgust.
Speedy possess all the abilities of a Speed Stinger and of his pack:
- Speed: Speed Stingers are renowned for being the fastest dragon species on foot.
- Webbing: His pack needed a way to island-hop so they evolved in a way that provided them with the ability to run on water using webbed feet.
- Sting: Because Speedy is still an adolescent, he can only cause partial paralysis in his victims, as his sting potency is not at full effect.
Hiccup was the first to meet Speedy as founded to be wounded. As Speedy shown to be very aggressive just like typical Speed Stinger but Hiccup didn't want to leave this baby Stinger alone thinking will die from its injuries. Hiccup was able to get some trust to Speedy by showing trust and it was working as Speedy as proven that the teens and their dragons to be pack.
Speedy has shown good relationship as Speedy was listing to Fishlegs commands little bit as he was showing to have good bond because Speedy is having new pack to listen well. But Speedy still stung Fishlegs on his arm but still had great bond.
Meatlug have shown to like Speedy as it was baby dragon that she shows some mothering to him as she was trying to nudge Speedy to be train with Fishlegs. She was even trying to save Speedy from running on water as they assume he will drawn since they are unable to swim but the riders have found out they can swim on water as to shock to Meatlug.
Speedy didn't like Snotlout at all as being mistreatment by him many times by his comments becuase of hateful of Speed Stingers kind have done to Snotlout stuns in the past. But still Speedy shows some respect to him because they are in the same pack as Speedy will defend Snotlout from his old pack.
Speedy and Hookfang didn't shown to interact munch but Hookfang might not like Speedy munch as he was bit scared of Speedy by getting loose from the ropes and stung him down to the ground. Like Hiccup stated that Speedy was part of the Edge Pack as he will protect the riders from harm as it possible Speedy will defend Hookfang since he is member of the pack.
His pack's island, where Speedy was found, could possibly be Speed Stinger island.
