Heat Vision

Heat Vision is the ability to project converted solar energy from the eyes. It is exclusive to Kryptonians.

Kryptonian's Heat Vision
Kryptonians can absorb large amounts of solar energy and convert it into any type of physical utility from their thermal body signatures. The excess reserves are then triggered at high levels of controlled heat allowing the body to gather enough force to expel the power at various frequencies and heating levels. In most cases, Kryptonians release this energy using visual perception, focusing all of their physical reserves to their retinas as concentrated heat emits through the pupils onto the directed location. The brain sends these signals to the retinas as a precaution to allow when it is safe to exhaust this overheating. The levels of these heat beams can vary, ranging from warm heat waving to extremely dangerous fire and laser levels. The beams at a burning point are very powerful and are shown to penetrate anything that it comes into contact with.

Kryptonians

 * Clark Kent (Kal-El) - Possibly one of the most powerful beings in the universe due to his extensive stay under a Yellow Sun which enhances his absorption. Being that he has lived on the planet Earth his entire life, it has given him massive amounts of solar energy to channel and master to control the various thermal settings he can use when using the power.
 * General Zod - in his short time on Earth, the Kryptonian general has shown to have gained certain control over the use of this heating power displaying adept use when he tried to strike down a group of human beings.
