Superhuman Durability/Invulnerability: Immunity to almost all forms of harm and ailments, including extreme force and extremely high temperatures. Explanations for this ability have ranged from Kryptonians having a molecular structure with a density superior to that of titanium and having strong bonds within the cells of his body that cannot be pulled apart.

Superhuman Breath: The ability to inhale and exhale huge volumes of air with great force, capable of extinguishing large fires and moving heavy objects such as cars. Super-breath also allows Superman to hold his breath for extended periods in airless environments. The release (exhalation) of highly compressed air through a valve (such as pursed lips) causes it to drop radically in temperature. This is known as the Joule–Thomson effect, and when Superman does this, it is usually referred to as Freeze Breath, Freezing Breath, Arctic Breath, or Ice Breath, and can cool almost anything to sub-zero temperatures and freeze air moisture solid, effectively creating ice.

Healing Factor: Superman is shown, especially in recent comics, to possess remarkable recuperative powers that allow him to quickly heal from wounds and makes him immune to all forms of human or Earthly diseases, illnesses, viruses and toxins. Superman heals faster when he is closer to the sun and absorbing more solar rays. Once, when his body was hit with the full force of a nuke, he absorbed solar energy from the plant life around him, re-energizing him, but killing the plants around him.

True Flight: Because Earth and the Sun exhibits less gravitational pull than that of Krypton, and also due to his solar-powered body, the Man of Steel can also alter his personal mono-directional gravity field to propel himself through the air and through outer space at will.

X-Ray Vision – The ability to see through solid objects, usually with the exception of lead. Early stories assumed that hiding objects in lead would prevent him from finding them; however, more modern stories have Superman being able to take advantage of lead's x-ray opacity to do a wide scan of an area with his X-Ray vision in which the lead objects become immediately visible and then narrow his search to those specific locations. Explanations for how this power works vary, but rarely include the emission and perception of actual X-Rays, as such high-energy radiation would actually be dangerous to living things on which he uses it. Another theory involves being able to see and concentrate on the patterns of natural cosmic radiation as it reverberates off objects. X-Ray vision was first used by Superman in Action Comics #11 (April 1939), where it was called "Superman's X-ray eyesight."

Superhuman Hearing – Can hear far more sounds with far more detail and at far greater distances than normally humanly possible, including sounds on frequencies undetectable by humans such as dog whistles. Superman is able to mentally screen out most of these sounds to be able to function normally, even in a noisy environment, and can focus in on specific things, like a person's voice or heartbeat, even if they are in another part of the city. He can sometimes be shown to hear sounds on other planets, which makes it likely that his hearing is fundamentally different from that of a human, as sound cannot travel through the vacuum of space. Like humans and most animals, he is skilled at automatically noticing his own name out of the jumble of several overheard conversations, making him adept at quickly responding to calls of distress all over the city.

Superhuman Vision – His senses grant him the ability to see farther and with greater accuracy and detail than humanly possible. Sometimes includes the ability to see EM frequencies invisible to humans, such as radio transmissions, infrared light, and the bioelectric aura which surrounds all living things, even in pitch-black darkness. Offshoots of this power include Telescopic Vision, which allows him to "zoom in" on far away objects, sometimes hundreds of miles away, and Microscopic Vision, which allows him to zoom in on objects that would normally be too small to see, like those on a cellular or molecular level.
