Glacius is a valiant and powerful alien entity which functions as a galactic marshal, upholding the tenets of universal justice across entire worlds. The alien Glacius is driven by chivalry to protect a young species with potential for greatness. Glacius' retro costume closely mirrors his appearance from Killer Instinct 2, although he still has four fingers and two toes from his default KI 2013 appearance. He retains his green eyes from KI2/Gold, although they look much more reptilian in nature. He now has four fingers (two fingers and two thumbs) on each hand and only two toes on each foot. He also lacks the smooth surface he had from the original game and instead has jagged, ice-like crystals emerging from various points along his body. His inner body is wiry and almost insectoid, but it is coated in a thick layer of ice that resembles the muscle mass of a human being. While still humanoid, his body is much more alien-like in appearance, with his limbs being thinner and his head now longer, shaped with mandibles. In Killer Instinct (2013), Glacius has undergone a dramatic change in physical appearance. He seems to be a bit larger than his previous form, and instead of having five fingers, he now has three, and his feet also have three appendages instead of coming to a boot tip.
More of his dark blue skin can be seen from under the white ice, and his eyes are in more of a glare than a blank stare. In Killer Instinct 2, although the Glacius featured is a different member of the original's species, his appearance has only minor changes.
If not, it is still possible that he has a mouth under the icicles on the front of his face. No mouth or nose can be readily discerned, but upon closer inspection, it seems as if the white ice around his face could be a type of mask. He has no ears, and his eyes are a dark blue with a black ring around them. His arms are a light blue and also glow, and his legs are a darker blue than the rest of his body. His entire body has ranges of blue and silver. Of a fairly large stature, the original Glacius also has a bit of a heavier weight for his physique, most likely due to the high density of ice and water that makes up his body. But when Earth comes under assault by the forces of Gargos, Glacius opts to stand with the juvenile species, and attempts to ensure its survival amidst the demonic onslaught. In Killer Instinct (2013), he's an interstellar warden who has come to retrieve alien technologies which the human race is not deemed ready to peruse. In Killer Instinct (1994), Glacius was taken captive by Ultratech and forced to fight for his freedom. A member of an alien species renowned for their potent telekinetic abilities, Glacius was left stranded on Earth and becomes entangled with humanity's affairs after Ultratech manages to steal advanced technology from his crashed vessel. Glacius is an extraterrestrial entity and a signature character of the Killer Instinct series, having been playable in every installment of the franchise to date. Light alone is harmless, but focused light is the most powerful force in the Universe.
