despair. Powers, abilities, and weaknesses The catalog of Superman's abilities and his strength has varied considerably over the vast body of Superman fiction released since 1938. Since Action Comics #1 (1938), Superman has superhuman strength. The cover of Action Comics #1 shows him effortlessly lifting a car over his head. Another classic feat of strength on Superman's part is breaking steel chains. In some stories, he is strong enough to shift the orbits of planets and crush coal into diamond with his hands. Since Action Comics #1 (1938), Superman has a highly durable body, invulnerable for most practical purposes. At the very least, bullets bounce harmlessly off his body. In some stories, such as Kingdom Come, not even a nuclear bomb can harm him. In the earliest stories, Superman's costume is made out of exotic materials that are as tough as he is, which is why it typically doesn't tear up when he performs superhuman feats.

Superman can project and perceive X-rays via his eyes, which allows him to see through objects. He first uses this power in Action Comics #11 (1939). Certain materials such as lead can block his X-ray vision. Superman can project beams of heat from his eyes which are hot enough to melt steel. He first used this power in Superman #59 (1949) by applying his X-ray vision at its highest intensity. In later stories, this ability is simply called "heat vision". Superman can hear sounds that are too faint for a human to hear, and at frequencies outside the human hearing range. This ability was introduced in Action Comics #11 (1939). Since Action Comics #20 (1940), Superman possesses superhuman breath, which enables him to inhale or blow huge amounts of air, as well as holding his
