Phantom is a legendary creature, a colossal jet-black Manta Ray, found only in Endless Ocean: Blue World. The title "Cyclades Phantasm" can be obtained by discovering it.

Encyclopedia Description

"This is the jet black manta seen in the silent ruins of Valka Castle. This foreboding creature roams the deserted ruins like a ghost. There is a superstition amongst the inhabitants of Ciceros Straits that the spirits of those who die at sea return as rays.

Could this be the shade of the former owner of the castle, the prince himself?"

[Phantoms of Valka Castle]

"Valka Castle, built by an eastern European prince in the 16th century, was said to be haunted even before it sank into the sea.

The ghosts were probably the vengeful spirits of peasants or enemy soldiers executed by the cruel prince. This explains why Prince Valka became obsessed with the occult and mysticism in his later years."


After he's been unlocked, the Phantom can be seen in the Mermaid's Ballroom of Valka Castle. However, he appears only at night.

How to Find It
After the main storyline of Endless Ocean: Blue World is completed, the player's notebook will remark upon several reports of a "ghost" in Ciceros Strait's Valka Castle.

At night, the player and Oceane must dive into the Castle, and Oceana suggests searching for the reported "ghost". The player expresses trepidation, but Oceana insists that they press on.

After a mysterious, unknown entity rushes by a few times, evading sight and documentation (as well as spooking Oceane and the player, earning some teasing from GG), the player and Oceana chase the creature into the Mermaid's Ballroom. There, it is revealed that the "ghost" is actually this mysterious, jet-black ray with a strange mark on its belly that is said to resemble the royal crest of the Valka family.


  • Phantom's coloration may be the result of a genetic mutation known as melanism, which causes excess amounts of melanin to appear within the skin of afflicted animals. While rare in fish, manta rays have been observed with the condition in the wild, and the Coney grouper (Cephalopholis fulva) and the western mosquitofish (Gambusia affinis) also have been observed to have this condition in rare instances.
    • Furthermore, he is one of only two legendary creatures in the game to possess this coloration, with the other one being the Black Harbinger.
  • Phantom is one of three legendary creatures to be found in an area separate from the other members of its species, the others being King Gigide and Kraken Jr.
