History:
Before Ninjago's creation, there were two kinds of beings with unfathomable power: the Oni and the Dragon. The Dragons had the power to create, while the Oni had the power to destroy; and so, they waged war against each other. One day, a child was born of both powers, the First Spinjitzu Master, who went on to create a world of light and darkness, these powers had been past down to him from their respective owners. From the shadows of the new world, the Overlord emerged. Risen to counterbalance the light of the land, the Overlord challenged the First Spinjitzu Master to a battle for control of Ninjago. The battle eventually ground into a stalemate, so the Overlord created the Stone Army to turn the tide in his favor. Realizing that he would be overcome, the First Spinjitzu Master used all of his strength to split Ninjago into two equal halves, which would later become two islands—one half remained as Ninjago, and the other became the Island of Darkness. This balanced the forces of light and darkness, preventing the Overlord from leaving the Island of Darkness as it slowly sank beneath the sea. For thousands of years, he plotted the events that would lead to his return.

Powers:
The Overlord was credited with the creation of the Stone Army, implying that he may possess the element of Creation (or a dark equivalent). In his orb form, he was able to float freely, allowing him to accompany Lord Garmadon wherever he travels on the Island of Darkness. He also appeared to have some form of enhanced perception, as he immediately sensed the Ninjas' arrival on the Island of Darkness. After using Lord Garmadon's body to retake a physical form, the Overlord gained enhanced physical strength and high durability, easily able to take Lloyd's attacks and overpower him, and the ability to release dark energy from his hands. He usually fired this energy as offensive beam attacks, which could overpower Lloyd's energy beams and break his legs, but he could also use it to fly; by releasing small "jets" of energy from his lower pair of hands, the Overlord was able to hover in the air or propel himself at varying speeds. In his original form, the Overlord's strength and durability increased even further, due to his massive size. He could fly with the use of his large wings, breath dark fire, and spit masses of pure darkness that corrupt anything they hit (much like the Garmatron's Dark Matter shots). At the end of his battle with Lloyd, he displayed the ability to transform himself into a large orb of shadows that engulfs his foe—within the orb, his head grew to many times its original size, although it is unclear if the rest of his body was still present or if the Overlord could simply manifest parts of himself at will within the sphere. Even before his transformation in the Golden Master, he was the most powerful enemy the Ninja ever met. As the legendary "Golden Master," his powers grew to be equivalent to, if not greater than the First Spinjitzu Master. Once he gained this power, he tried to shoot Kai with a beam of Golden Energy. Also he was able to use Golden Energy to levatate cars in mid air. He even threw one at Nya. When the Ninja got Stone Armor, the Overlord, like the First Spinjitzu Master, shaped roof tiles into a massive arm and hand in a attempt to crush the Ninja; despite this, he failed to crush them. At the end of the episode, he was powerful enough to ensnare the Ninja with beams of Golden Power. Though, this shouldn’t have been possible as the stone armor the Ninja were wearing was supposed to be resistant to the might of Golden Power.
