Ectonurites are aliens from the planet Anur Phaetos.
Ectonurites are undead alien hybrids. Their basic forms don't look very scary and resemble a classical ghost. It's actually second skin layer to protect them from the sun. Their true form is quite hideous and scary. Ectonurites carry frightening skeletal appearance which is concealed by their second skin layers. They have upside down skulls and only one eye, however the eye can move to any part of the body giving 360° sight. They have exposed bones in places. They have dark blue skin and claws. Ectonurites have a place on their chest which can open to reveal tentacles. They speak with an eerie and creepy voice and are said to be one of the most frightening aliens in the galaxy. They also lack mana
Ectonurites from Anur Transyl have mouths, 2 eyes, and stitches.
Ectonurites are ghost like creatures with ghost like abilities. Like Ghosts, they are made of protoplasm. This allows them to change their matter to the point that they can become invisible and pass through any solid object. Ectonurites are also capable of telekinetic abilities and possessing other lifeforms for a period of time. They can also release a blast with the tentacles on their chest. Ectonurites have the remarkable ability to be remade from a molecule of DNA.
Ectonurites cannot be exposed to direct sunlight as it will kill them or cause great bodily harm, unless they have a second layer.
Ectonurites' protoplasm can be stolen by protoplasm freezing spray.
- According to Duncan Rouleau, the Omnitrix from the Ben 10 reboot contains Ectonurite DNA. Therefore, Ghostfreak is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
