The Black Rock Spikes are mysterious sharp spikes of rock that came out of the ground surrounding the spot where the magical flower sprouted from, and later played a part in the return of Rapunzel's long hair.
These black rocks are located around Old Corona village and in "The Alchemist Returns", it is revealed that the black rocks were spreading to the kingdom of Corona, where the ancient Sundrop Flower descended to.
The black rocks vary in size. The grow just about anywhere, (although it has not yet been confirmed that they can grow in the sea or any other body of water) and are normally a black color, except they glow a bright blue when they are near (or come in contact with) Rapunzel, or they just spike out of the ground. When touched by Rapunzel, they usually create a large, powerful, and dangerous bright-glowing blue blast. Most of them have a small spike on the side of them, near the end. They often grow in clusters, and after Rapunzel uses them, they all pointed in the same direction.
Sometime before Rapunzel's return to Corona, these mysterious rocks started to sprout out of the ground where the royal guards found the flower that saved the Queen Arianna and her unborn child. The only thing that is known about the rocks is that they are unbreakable and that the rocks are tied to the Opal years ago. Cassandra, brought Rapunzel to rocks while sneaking her out for some downtime. When Rapunzel reached out to touch one of them, a powerful blast from the rocks knocked the two girls off their feet and somehow grew back Rapunzel's long hair.
Afterwards, the rocks began to sprout throughout the land. They started to appear around Varian's village, Old Corona. Every time Rapunzel went near them, her hair would glow along with the rocks, indicating that they are somehow connected. Varian promised to help Rapunzel and Cassandra understand the rocks better and to keep their work a secret. As the number of rocks grew started to destroy the village, Varian knew that they would not stop "growing". Once they had destroyed his village they would start making their way to Corona. Varian desperately tried to use alchemy in his attempt stop them, until his experiments got his father "crystallized". in gold amber infused with the spikes.
In "The Quest for Varian", Rapunzel used her hair to interact the rocks and triggered a shock wave to stun the troops chasing her, but it caused the rocks rapid growth and destroyed the tower eventually. An ancient scroll revealed that the rocks may be caused by the drop of moonlight, with reference of the Magical Golden Flower which came from the drop of sunlight.
In "Secret of the Sun Drop", the rocks slowly begin to encroach on Corona. Following Varian's abduction of the Queen, King Frederic confesses to Rapunzel that he had known all along what the rocks were, revealing that the night of her birth, he was warned by Quirin against removing the flower, least he would reap unimaginable consequences and awaken a darkness, which resulted in the emergence of black rock spikes.
During the battle in Old Corona against Varian's army of automatons, Eugene gets an idea to lead the automatons to the rocks to destroy them. Meanwhile, Rapunzel and Frederic are trapped by Varian in a failed attempt to ambush him. Varian then uses her unbreakable hair as a drill tip in an effort to drill through the amber, but it fails. In the end, the black rocks converge on Rapunzel when Varian threatens her mother and Cassandra with a giant automation. Rapunzel realizes that this was her destiny and she shouldn't run away from the rocks, but she is supposed to face them. Rapunzel then grips the rocks and successfully controls them to defeat Varian and his automatons. Having an epiphany, Frederic admits he thought their purpose was to destroy Corona, but ignoring them only made the danger worse. The rocks then breach the kingdom's border wall and begin to lay flat, pointing to the certain direction, which Rapunzel was encouraged to follow.
In the aftermath, the black rocks are revealed to be breakable by Adira with her black sword.
In "Beyond the Corona Walls", the episode's prologue reveals that the rocks had existed and corrupted a kingdom twenty-five years ago (years after the Sundrop Flower had rooted its mystical healing/life-bestowing powers onto Corona). Rapunzel, Cassandra, Eugene, Lance, and Hook Foot are on a caravan following the path of the rocks - with Shorty as a stowaway - being pulled by Max and Fidella. It eventually leads them to a once great town called Vardaros. In the evening, Rapunzel tries to destroy Eugene's wedding to Stalyan with one of the black rocks. When nothing happens, Adira states that it's because the rocks have found the mystical Sundrop (now having transferred to Princess Rapunzel) in this case.
Having left a trail for the Sundrop Flower (Princess Rapunzel's blonde hair) to follow in order for the Sundrop and Moonstone to unite and call upon the greatest power of the heavens for one to wield as he/she saw fit. At the Dark Kingdom, from which they originated from the all-powerful Moonstone as a defense mechanism, their allegiance seems to have changed.
As Cassandra takes hold of The Moonstone Opal and unleashes its immeasurable powers, she merges with it and thus the black rocks grow at an incredibly fast pace and point toward her. Their evil magic has now given Cassandra a black-and-blue bodysuit made from them. It is then that her hair and eyes turn a light blue; the very same light whenever their powerful dark magic is activated.
Now having merged with Cassandra's body, mind and spirit, the Moondrop Opal bestows upon the lonely and luckless teenage daughter of the late Mother Gothel its array of supremely powerful moon-based abilities. Its supreme strength and evil magics seem to have grown considerably stronger since it had called forth the magical shadow sword, which was forged from its ever-moving defenses, to its host's hand.
Later on, at the urging of Zhan Tiri, Cassandra succeeds in tapping into the depths of her deepest rage and hatred she now feels towards Princess Rapunzel and completely control them with the second Moonstone spell. She was fully capable of creating an entire tower out of them as well as a throne, staircase and cages and elevator.

Being an essential part of the ancient, all-powerful Moonstone of the Heavens itself, which is the heavenly force of darkness and evil, they arise mainly to keep any from managing to possess the almighty Moonstone Opal and harness its dark powers fully:
- Negative Force Manipulation: As with the decaying spell, the Rocks have power to bring forth intense destruction, death, weakness and decay to those around them, even on the verge of death itself.
- Nigh Indestructibly: Most physically substances have no affect, with the exception of Adira's shadow sword; made from the rocks themselves.
- Encasement: They even have power great enough to surround its enemies and trap them into impenetrable rock-like prisons. Quirin is the first ever to become utterly encased in them, though their evil magics were notably assisted by the gold amber in Varian's laboratory.
- Feeling/Emotion Response & Manifestation: Now that they have a human host to harness their sinister moon-related powers fully, they now change to a certain color reflecting to her deepest feelings; first were "fear" and "doubt."
- Lunar Matter Manipulation & Control: Thanks to the secondary Moonstone spell, Cassandra can create and reshape the black moon rocks to her will, from a cage, to stepping stones, Cassandra's Stronghold.
They can indeed be severed, but only with the magical shadow sword wielded by Adira, which was forged by the Black Rocks themselves a quarter of a century ago.
