Clark Kent's Kryptonian body acts as a solar battery absorbing solar energy which can then be used as various remarkable powers. If Earth had a red sun like Krypton's, Clark would not have these powers. Using his powers causes Clark to use up his stored yellow sun energy. He can lose his powers if he expends a lot of energy quickly (e.g. during his battle with the monster Doomsday) or if he spends too much time away from a yellow sun while in outer space. When low on solar energy, Clark can 'recharge' if exposed to a source of yellow sun energy. The rate at which he 'recharges' can vary.
Superman's superpowers
include:
Strength - although varying depending on his energy levels, Clark is among the strongest superheroes on Earth, capable of lifting a plane.
Flight - able to defy gravity, possibly through sheer force of will
Invulnerability - Years of exposure to yellow solar energy have caused Clark's Kryptonian body to become almost indestructable. His natural bio-electric aura also has limited force field properties protecting items near his skin e.g. his costume.
Clark can survive in outer space as long as he has a breathing apparatus, and doesn't lose too much solar energy. Using his powers of flight and super-speed Clark can travel inter-planetary distances by himself. Interstellar distances require assistance e.g. a spaceship.
Super-speed - capable of superhuman speed, Clark can fly from Metropolis to have dinner with Lois Lane in Paris, France, or in a few minutes fly to the Moon.
Super-breath - Clark's invulnerability and strength exist internally too, affecting his skeleton and internal organs. After inhaling deeply he can expel the air in a gale-force wind.
Super-hearing - Capable of blocking out and discerning a single known voice within a city
Vision - Clark can
detect electromagnetic energy in more than the normal visible spectrum:
X-Ray vision -
lead appears opaque
IR vision
Microscopic
Telescopic
Heat Vision - Additionally, Clark can release solar energy in the form of Heat Vision as a weapon.
Besides the using up of his solar energy, Clark has two other weaknesses:
Super Science (sometimes called Magic)
