"Just as there is an atmosphere around Earth, we are merely existing here. That's why the other world needs our existence. A parallel world to this one. Yes. The world that you live."
"The world where I live?"
"Now it's about time to end this. Your use is already over, Ultraseven."
- ―Grakyess communicating with Jin's mind while he was Ultraseven X
Grakyess (グラキエス Gurakiesu) are an unknown alien species which appears in Ultraseven X TV series. They serve as the ultimate antagonists and there is reason to believe they may be responsible (at least indirectly) for all, if not most, of the incidents concerning the protagonists faced before and during the series. The gestalt being ruled mankind by covertly taking over all forms of media and flows of electronic data, forcing mankind into a state utopia by ending all wars and conflicts. Their nature as data parasites and their control over the A.I. that ran DEUS gives reason to wonder if they had anything to with the various alien invasion attempts and incidents that plagued mankind much greater number after their rise to power. In a last effort, they create three mechanical and gigantic versions of themselves, Mecha Grakyess (メカ・グラキエス Meka Gurakiesu) to combat Ultraseven X.
- Graykess: Small Assembly (小型集合体 Kogata-shū Gattai)
- Mecha Graykess: Giant Machine Organism (巨大機械生命体 Kyodai Kekai Seimeitai)
Grakyess, also called the Shadow Rulers, are the hive mind of the Graykess aliens who ruled the alternative Earth of Seven X's World. The trio were seen at the beginning of the series watching Jin via an unseen Graykess drone. They were not seen again in the series until the final arc but mentioned numerous times by Elea. They ran the world by controlling its information and when Project Aqua proved to be able to create a gateway to another universe they sought to use it to conquer the world on the other side. Soon, the Grakyess soon finding out how close Jin was to discovering the truth they deployed the three Mecha Grakyesses to stop him only for him to turn into Seven X. However, the three Mecha Grakyesses were too much for the hero to handle and was forced to turn back into Jin. After some encouragement from Elea, Jin turned into Ultraseven X again, this time with Seven in control and destroyed the three robots with little trouble. When Ultraseven X was being defeated by the Mecha Graykess, Jin, whose mind was in control of both bodies, was contacted by them telepathically so they could mock him and justify their invasion of both worlds by stating that mankind's need for information made their presence natural and required. Seven X then burrowed deep underground after killing a Mecha Graykess with the Emerium Beam to find thousands of Grakyess in their hives. Using a combination of the Eye Slugger and Wide Shot, Seven X destroyed them by the hundreds at a time, ending the Grakyess rule over mankind and allowing Seven to return to his home universe.
- Graykess represents the first instance of an alien actually conquering the Earth in the Ultraman Series.
- Their nature as the face of a hive mind makes them similar to Yapool who was said to be the combination of the minds of the species he takes his name from.
- When Grakyess communicated with Jin, it seemed as though they were speaking directly to Ultraseven and held no regard for Jin. Whether they knew that Seven was in a forced coma at the time is unknown.
