Scorponok was a powerful Decepticon warrior who aided Megatron in his war of conquest on Cybertron. Somewhat counter to Megatron's personal style of guile and subterfuge, Scorponok chose to conduct himself in a more direct manner, leading from the frontlines and being at the forefront of many battles.
Set ten years after armada, Energon, opens in an age of peace on Cybertron and Earth which is destined not to last long. Energon pits the Autobots against an array of villains: the reborn Megatron, the barely functional Unicron, and the mysterious Alpha Q and his Terrorcon minions.
When Hiccup first chose The Windwalker to be his riding dragon, it was because of his nervous and traumatized look and that he knew no one will choose him. The Windwalker is jumpy and edgy, he looks to be in fear of something. Furthermore, he seems to be mute at first, but it was proven wrong when he told Hiccup to 'desert' in a soft whispering. However, he is fiercely loyal to Hiccup, as all the other riding dragons fled when the Vikings were surrounded by fire and Extermintor younglings on a hill, but he remained, protecting the Vikings from the heat as Gobber's riding dragon, Goliath, carry the young Vikings to safety.
As The Windwalker matures, he turns out to be a very gentle and soft spoken dragon. He still talks awfully little in the books, though. He is still pretty jumpy, but apparently he gains more confident in himself as he grows up. His loyalty to Hiccup is stronger than ever, proven when most other dragons were taken over by the Red-Rage during the Dragon Rebellion, but he was only confused by it. He still gets spooked easily and tends to be confused when totally freaked out. Lately, his reflexes have been sharpened in the year living as an Outcast.
