The Stealth Scrapadactyls are the main antagonists of the episodes Pteracopters and Picktools (alongside the Arctic Scraptors). They are a subspecies of Scrapadactyls which are skilled at avoiding being hit.
A Stealth Scrapadactyl looks like a regular Scrapadactyl, but with a darker body and trademark laser sights that shine from their red eyes.
Stealth Scrapadactyls act just like regular Scrapadactyls, flying during both day and night and stealing scrap, but also keeping watch with their motion-detecting laser vison. They end up getting hit less often than their regular counterparts, which makes them even more dangerous.
