Prime's powers and abilities
Kevin transforms into Prime by projecting an organic 'liquid flesh' material from his torso. The liquid flesh then shapes itself into a tall man with exceptionally large and defined muscular development. Prime can revert to his teenage form by destabilizing the outer body into a mess of protein goo, either consciously or when his Prime-body's energy reserves run out. When this happens, Kevin must pull himself out of the body's remains or risk suffocating from lack of oxygen.
As Prime, Kevin possesses tremendous strength with unknown limits and once lifted an entire outdoor gym with relative ease. His resistance to physical injury is also exceptionally high, having survived a close proximity explosion of several nuclear warheads. Prime can also fly at Mach-level of velocity. Although all of Prime's powers are modelled after traditional superhero powers, these limitations are defined mostly by Kevin's subconscious aspirations.
In fact, it is frequently suggested that the appearance of the Prime-body is formed mostly by Kevin's subconscious. Many of the features of the Prime-body are taken from Kevin's role models such as action stars and comic book superheroes. Another Ultraverse character who shares a similar origin, Elven, is a fan of Elfquest comics and creates a body for herself that is a mishmash of various Tolkienesque fantasy elements. The face of Prime also bears a striking resemblance to Kevin's own father, Russell Green.
In effect the Prime-body reflects Kevin's own attitudes towards heroism at any given moment. As such, Prime's physical appearance has changed numerous times. Common elements exist among the different Prime-bodies though, such as a stylized 'P' resting somewhere on his chest or cape and some metallic adornment such as chains or gauntlets. Some of his forms include:
First Prime - A Prime-body obviously inspired by comic book superheroes, as well as local bodybuilders from Kevin's home state. As the first Prime-body, it defines the visual template for the other Prime-bodies. The body possesses extremely developed muscles and prominent veins. The costume is made up of a large red cape, red pants, gold gauntlets, calfguards and chestplate and features the trademark stylized 'P' on both the cape and the chestplate.Space Prime - A Prime-body meant to withstand to harsh conditions of outer space. This design was force fed into Kevin's subconscious by military scientists working for Colonel Samuels. The epidermal layer has been transformed into a hardened shell resembling some kind of metallic alloy, designed to prevent the body from expanding in the vacuum of space. A set of air-tanks exist in the subdermal layer. The gold gauntlets, calfguard and chestplate remain as well as the 'P' insignia on his chest, but the cape is absent (in the Ultraforce cartoon, it was Contrary who suggested to him changing form).
Rogue Prime - A Prime-body inspired by rugged individualistic heroes such as the gun-toting antihero Firearm. The body also sports a series of gold chains around the waist, and a set of spiked armbands and headgear. Tattoos and piercings are also notable, as well as a scar on the right eye. The color scheme is radically different, with the 'P' insignia being black on gold, and the vest being dark blue rather than gold and leather gloves replace the gauntlets. In the Ultraforce animated series, Rogue Prime is created when Kevin falls under mind control, as well as from his inner doubts.
Final Prime - A Prime-body that reconciles the values of Rogue Prime with the inspirations of the First Prime. The visual appearance is closer to that of the First Prime than the Rogue Prime --- cape, gauntlets and all --- but sections of the cape and pants mix blue and red. Hints of the Rogue Prime exist in the form of tattoos, albeit much fewer in number than in the Rogue Prime. There is a slight amount of arm-hair, also a residual element from the Rogue Prime.
Spider-Prime - A Prime-body inspired in part by Spider-Man. When Kevin was trapped in the Marvel Universe, he only had half of his power. When he tried to become "primed up," he became a mass of slime and unable to control himself. When he tried to help Spider-Man fight the Lizard, he changed into Spider-Prime. This form was a smaller version of Prime with a face mask and gave him six arms. Kevin transformed twice more into a variant version of Spider-Prime, however this body he claimed was 'not Spider-Man's anymore', indicating that somehow the first Spider-Prime may have been a direct imprint on Spider-Man. The second Spider-Prime, like the first, had a red and blue color-scheme much like Spider-Man, along with a mask with red around the eyes, but it also included gauntlets and a massive golden spider on the chest, along with boots to match the gauntlets. The second Spider-Prime had no extra arms except for a singular use in battle with the primary Prime body, which was a one time thing[clarification needed]. Both of the second Spider-Prime transformations enabled Kevin to use webbing.
