-Superhuman strength - Physical strength far exceeding that of a normal human or any other known animal. The upper limit of how much weight he can lift has ranged from several tons to entire planets. Explanations include being adapted to the heavier gravity of Krypton, and his muscles using the power of the solar energy which fuels all his abilities. Superman's stamina is also limitless (whilst he remains in yellow sunlight).
-Invulnerability - Physical invulnerability protecting his body from almost any form of harm. Effectiveness has ranged from his skin being piercable by nothing less than a "bursting shell" to being completely unharmed at ground zero of a nuclear explosion. Includes the immunity to most known diseases, viruses and toxins.
-Flight - Ability to propel himself through the air at will. Has ranged from simply being able to jump great distances using his superhuman strength, to being able to accelerate, float in midair, change direction and traverse interstellar distances without stopping.
-Superhuman speed - Ability to move at speeds far greater than normal humans are capable of. Top speeds have ranged from hundreds of miles per hour to speeds far greater than the speed of light. Includes the speeding up of his thoughts and perception to be able to control his actions as well as normal while moving at high speeds.
-X-ray vision - Ability to see through solid objects, usually with the exception of lead. 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 he uses it on. A more common theory involves being able to see and concentrate on the patterns of natural cosmic radiation as it reverberates off objects.
-Heat vision - Ability to emit heat energy from his eyes. Usually resembles bright red or orange laser-like beams, which may be invisible at low temperatures but extremely bright at high ones.
-Super breath - Ability to inhale and exhale huge volumes of air with great force, capable of extinguishing large fires and moving heavy objects such as cars. 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.
-Super hearing - Ability to hear far more sounds with far more detail 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.
-Superhuman vision - Ability to see farther and with greater accuracy than normally humanly possible. Sometimes includes the ability to see EM frequencies invisible to humans, such as radio transmissions, infrared light and in some stories, even an energy aura which supposedly surrounds all living things (this originated in Superman: Birthright).
-Superhuman Olfaction - A heightened and highly accurate sense of smell comparable to some animals such as dogs. Can be used to detect things like the chemicals in a bomb hidden somewhere in a crowded room.
-Eidetic memory - Superman is occasionally shown to have flawless, total recall of everything he has ever seen, read or heard. In turn, he is often depicted as being fluent in many of Earth's languages. This "power" is shared by a number of real-life people such as Kim Peek, but in Superman's case it is likely a result of his invulnerability preventing any cell in his brain from deteriorating and related to his mind's ability to perceive events at superhuman speeds as if they were happening at normal speeds.
-Superhuman Sound - Superman can whistle very loudly reaching almost 100 decibels on the Decibel meter. His whistle can stun dogs.
