Morro Storm

As a child, Morro had brown hair and wore gray-green cloaks. As a ghost, his body became translucent and green, his clothes more ragged, a dragon symbol was visible on his chest, and his hands and face glowed pale green. His black hair fell just below his ears, with a green streak in his bangs.

Morro is the Master of Wind and a descendant of the first Master of this element. As a child, he was discovered by Master Wu and taken as his apprentice. Morro sincerely believed he was destined to become the Green Ninja—the legendary warrior of prophecy. But when the Golden Weapons did not choose him, the boy became embittered: he accused Wu of "unfair fate," left the monastery, and set out in search of the tomb of the First Spinjitzu Master.

Morro is one of the most memorable characters in the Ninjago universe.

After the Second Serpent War, Morro found himself in the Cursed Realm and became a general in the ghost army, serving the ruler of the Preeminent.

Story arc
Morro's key story unfolded in the fifth season of the animated series. He escaped the Cursed Realm and set out to find the Realm Crystal hidden in a tomb. The problem was, only a Spinjitzu master (Lloyd) could show him the way to the tomb. So Morro possessed Lloyd's body.

Using the Azure Allied Armor, he could summon other ghosts. Morro obtained the Staff of the First Spinjitzu Master (which Wu had), and then traveled to the Cloud Kingdom to retrieve the Sword of Sanctuary. Ultimately, he obtained the Realm Crystal and freed the Preeminent—so she could curse all sixteen realms.
