“Behold, the key to unlocking the dark powers of a lost age. When the blood moon arrives, we will assemble the most powerful beings in the Merged Realms.”
Lord Ras is a warrior from the Realm of the Wydlness, and the former leader of the Claws of Imperium. He is the overarching antagonist of Ninjago: Dragons Rising, and acts as a major antagonist in the first season, the main antagonist of Season 2, and a major antagonist in Season 3.
Coming from the Wyldness even before the Merge, Ras moved to Imperium and assisted Empress Beatrix to gain control of the kingdom. Despite being a capable commander and a highly professional warrior, he has failed multiple times to stop Arin, Sora, and Lloyd from freeing and escaping with the dragons Imperium had captured. Consequently, Ras was stripped of his title as leader of the Claws and imprisoned for his failures by Empress Beatrix, who now decided to do the job herself.
During the MergeQuake Storm, Ras managed to escape his cell and, in the aftermath, recruits Jordana for her achievement in extracting energy from a Source Dragon on behalf of his master. Together they awaken the Wolf Mask Warriors in order to resurrect the Forbidden Five so they can participate in the Tournament of the Sources, obtain multitudes of Elemental Power, for a goal currently unknown to serve his master. Ras is defeated and the Forbidden Five betray him, but he gains the ally of Arin the Ninja.
