Galactica is a humanoid alien whose entire body is solid black (excluding his hands, which are white). He has tiny white star-like spots all over his body, giving him the appearance of a starry sky. His eyes are blue and pupiless, and his forehead bears three horns. Later in the series it is implied that the starry form isn't simply aesthetic but that Galactica and by extension all Celestialsapiens are or contain their own pocket universes.
Pitch black darkness overtakes the light from the Infinity on Bryce's wrist, and creeps up his arm toward his face. Bryce's terrified eyes are swallowed by the void as the camera zooms in, being taken over as well. A tiny light bursts awake in the darkness, followed shortly by others; the closest one's resembling stars exploding into life. Zooming back out, Galactica is revealed, his arms broadened. Green light erupts from behind him.
In The Darkest Night: Part Two, Galactica was used to block an attack from Death Dragon, accidentally causing the attack to hit Marissa Harper. He then evolved into Ultimate Galactica to kill Death Dragon.
Powers and Abilities
Galactica is omnipotent, being able to warp reality, time, and space with ease and at any level he wishes. Even his thoughts can become real.
Galactica can create time waves to reverse events.
Galactica can create an entire universe at will. He is also very durable, as he was able to resist an attack from Death Dragon's Death Fire, which is supposed to kill anything that it's aimed at.
Galactica can self-duplicate and create galaxies to suck in other beings. He is also capable of high speed travel, superhuman strength, and the ability to grow to a gigantic size.
Galactica possesses telekinesis.
In order for Galactica to perform any action, including simple movement and transforming back, at least two of his personalities must agree to do so. This is shown by Galactica always saying "Seconded. Motion Carried", implying that two of the personalities agreed. This has proven to be a major weakness, as Serena and Bellicus have opposing personalities and it's hard for them to agree.
Galactica is vulnerable to having his powers absorbed.
Other Celestialsapiens can harm Galactica.
According to Derrick J.Wyatt, even Galactica can't survive on Anur Vladias.
- It is said in his weaknesses that "at least two of his personalities must agree to [perform an action]", but it was seen that this is not always the case.
- Despite being unlocked by Bryce, Nemevoc's Ultimatrix does not have a Celestialsapien form.
