Slab is a dragon that was captured by the Dragon Hunters and was used to fight prisoners for the Hunters' entertainment. He is shown to have the Elemental Power of Earth and is not weak to Vengestone.
He appears as part of the Dragon Hunters' entertainment, where he is put in the Pit with a prisoner, and he is expected to kill them. Zane, Kai, and Jay are thrown into the Pit, and Slab is put to fight them.
While on the ground, Slab is about to blast Jay with his Earth breath when Zane uses his Elemental Power of Ice to freeze Slab's head. This display causes the Hunters and Iron Baron to realize the ninja are Elemental Masters, not Oni as believed.
Slab's frozen body can be seen as Kai, Jay, and Zane battle the Dragon Hunters, though he does not partake in the fight.
Slab follows its fellow dragons through a portal that forms in the skies of Ninjago. It helps Cole save his friends from the Sons of Garmadon. Cole later flies on the dragon to evacuate the citizens and destroy the Colossus.
In the end, Slab and the other dragons return to their realm.
In "Iron & Stone," Slab has the ability to manipulate and breathe Earth and blast sand from his mouth. He possesses supernatural strength and durability. He also has a clubbed tail that is presumbly used for melee attacks. He can also sense the presence of an Oni (this may not be a unique power, but instead a shared power of dragons as a whole). Despite these abilities, he has weaknesses; he is slow and lumbering, and cannot fly at fast speeds (unlike the Wind Dragon).
