Jason's cellular structure is much more dense, resilient, and biologically more effective than human tissue. He does not possess superhuman strength levels despite his enhanced cellular ability without his cellular structure charged with yellow solar energy. Without such charging, his physical capabilities are identical to a human of his height and weight who engages in regular physical activity. As an alien, he possesses several organs whose functions are not yet disclosed or understood, but are believed to be part of or the source of his bio-matrix force field and reclamation aura. Jason Bourke's body also stores energy actively within his bio-cellular matrix as an energy pattern that is linked to his body's electromagnetic field. This energy powers most of his electromagnetic capabilities such as flight, heat vision and other "sight"-based abilities while supplementing his physical abilities to superhuman levels.

 

Solar Radiation Absorption: As a Kryptonian, his cells function like a super battery, hyper metabolizing specific wavelengths of radiation as fuel to enable living functions and/or superhuman abilities. Different wavelengths of radiation have different effects on Superman's physiology and well being, but his cells cannot absorb or utilize all types of radiation. The wavelength of his home solar system's red sun enables his body to function on an identical level of a healthy human while the Earth's solar radiation in both its raw and filtered state through the Earth's atmosphere acts as fuel to enable all of his powers. Every time Jason uses any of his superhuman abilities, his body expends absorbed sunlight and he is capable utilizing any of them to various degrees through controlled circumstances. The solar-based radiation of a foreign blue star proved to increase his known abilities under a yellow sun to a higher degree and enabled additional powers. The existence and constant exposure to proven "healthy" radiation sources is not required for him to live and utilize his powers, but prolonged periods without exposure to them and/or utilizing his powers will require Kal-El to recharge in order to live and continue using his powers.

 

Superhuman Strength: The exact limits of Jason's strength is unknown, but he has been shown as capable of lifting far in excess of one billion tons. Different periods and intensities of exposure to Earth's solar radiation can cause his strength to fluctuate over time. Jason's known feats include lifting an enormous pyramid and flying it to Mars without any strain, physically defeating Darkseid in combat, moving Earth away from the Sun with the aid of Green Lantern while Starbreaker was pushing it toward the Sun (a feat that at minimum would require quintillions of tons of force), and having the strength necessary to shatter planets with individual blows. When fighting a version of himself from a different world he shattered the boundaries of space and time, saying "the universe is in it's death rows". Unhealthy levels of high exposure to solar radiation can exceed Jason's "normal" strength level.

 

Jason's Speed: He is capable of moving, reacting, running and flying at superhuman speeds. While not as fast as the Flash, Superman can still fly at speeds faster than light and is considered one of the fastest beings in the universe. He can use this power to disarm opponents, catch bullets or shrapnel and cross vast distances in seconds. This also confers:

​

Superhuman Agility

​

Superhuman Reflexes

​

Superhuman Stamina: He has the ability to maintain continuous physical actions for an undefined period. Jason is shown to have unlimited stamina if he is consistently exposed to Earth sunlight.

​

Flight: Jason Bourke is capable of flying at supersonic speeds (over two thousand miles per second) in a planetary atmosphere and at faster-than-light speeds while in space. He once travelled from the Vega star to Earth - a distance of over 25 light years - in minutes if not seconds, meaning he is capable of flying over one million times the speed of light.

​

Heat Vision: Jason Bourke can fire beams of intense heat from his eyes. These beams can be made invisible, allowing him to work undetected, and can be adjusted to affect matter on a microscopic level. Feats include powering up the giant ion planet moving engines, annihilating an army of Doomsday clones in one blast, potentially rivaling the heat of a Star and bypassing a target's outer shell, avoiding damage to a person's skull for surgical purposes.

​

Invulnerability: His body is nigh-invulnerable due to his superhumanly dense cellular and anatomical structure as well as his radiating bio-electrical aura. Jason Bourke is under some circumstances resistant or immune to different forms and levels of lacerations, blunt force trauma, energy-based assaults, falls from great heights, explosions, the cold void of space, toxins and all known diseases on Earth. His supercharged bio-electric "aura" acts as an invisible "force field" radiating within a few millimeters from his skin. He can willfully utilize his aura strengthening it's power to a greater degree to provide an additional defense against certain levels of physical and energy attacks for a considerably short period of time, but doing so can endanger him should the attempted feat prove inefficient for any reason. Superman utilizes his aura by expanding it around a person(s) or object(s) to enable their structural stability when lifting or traveling with them. Jason's invulnerability has been in constant flux over the years. He has been shown surviving the blast of nuclear warheads, entering the Earth's sun and emerging unharmed, withstanding the impact of an exploding star, and surviving being in the vicinity of an explosion equal to 50 supernovas while already significantly weakened by red sunlight
