Captain America represented the pinnacle of human physical perfection. He experienced a time when he was augmented to superhuman levels, but generally performed just below superhuman levels for most of his career. Captain America had a very high intelligence as well as agility, strength, speed, endurance, and reaction time superior to any Olympic athlete who ever competed. The Super-Soldier formula that he had metabolized had enhanced all of his bodily functions to the peak of human efficiency. Most notably, his body eliminates the excessive build-up of fatigue-producing poisons in his muscles, granting him phenomenal endurance.
Captain America had mastered the martial arts of American-style boxing and judo, and had combined these disciplines with his own unique hand-to-hand style of combat. He had also shown skill and knowledge of a number of other martial arts. He engaged in a daily regimen of rigorous exercise (including aerobics, weight lifting, gymnastics, and simulated combat) to keep himself in peak condition. Captain America was one of the finest human combatants Earth had ever known.
In compensation for his lost sight, Daredevilís other four senses have been preternaturally enhanced.
His sense of touch is sensitive enough to detect the faint impressions of ink on paper, allowing him to read by touch. He is also able to feel minute changes in temperature and pressure, enough to sense a human body at a distance of five feet, due to body heat and air disturbance. His sensitivity to heat allows him to sense the temperature of people and objects in order to determine whether a person is alive, how long they have been dead if they are not, and other changes in body temperature such as blushing or the heating up associated with various emotional states, as well as residual body heat on an object, or how recently a machine has been in use.
Daredevilís sense of smell is enhanced enough to distinguish individuals by their natural odors, and remember and identify them no matter how they attempt to mask their scent, as well as track that individual scent through a crowd of people at a distance of roughly 50 feet.
His sense of taste is sharp enough to enable him to detect the number of grains of salt on a pretzel. His ability to remember tastes enables him to determine every ingredient of a food or drink he tastes, as long as there are at least 20 milligrams of that substance present.
Daredevilís enhanced sense of hearing enables him to detect an acoustic pressure change of 1 decibel at a pressure level of 7, whereas the average human can only detect a sound as low as 20 decibels. He can even hear people speaking through a standard soundproofed wall. Daredevil is also able to hear a heartbeat from 20 feet away, as well as identify people by their individual beat rhythm, or detect whether they are lying or not by the changes in their heartbeat, though a pace maker or self control will confuse his reading. Not only does Daredevilís hearing allow him to be constantly aware of his own heartbeat, blood circulation, breathing, physical movements, etc, but he is also able to hear and sense the same attributes in other people. One of the primary ways he does this is by hearing the reverberations made by ambient sounds on objects and people, giving him a sonar-like sense of where things are, and how dense they are. And while he is able to block out a good amount of background noise, he can also be excessively disoriented by unexpected loud noises and can be confused when immersed in the wash of sound from a busy crowd.
Along with the enhancement of Daredevilís normal senses, he has gained another sense which he calls his Radar Sense. According to one theory, this sense reacts to an emission of electromagnetic energy a mutation in his brain has caused, reading the reverberations of this energy as a 360º, 3-D map of objects. This ďsightĒ is not perfect, and can only give Daredevil an impression of the exact physical shape of objects, not a literal one. Closely overlapping objects can also confuse this sense.
The mutations that have heightened Daredevilís level of sensitivity have also increased his awareness of other forms of electromagnetic radiation. He is capable of detecting and identifying any electromagnetic radiation on the standard scale; from radio waves, (which he can only detect, not understand the message) all the way to gamma waves, and everything in between. He is also able to judge the strength of a given radiation and even differentiate between individual colors by the amount of radiation they give off. At very close range, Daredevil is able to detect the micro voltage of a human beingís brain.
Daredevil possesses the strength, speed, agility, and endurance, not to mention acrobatic and gymnastic skills, of an Olympic-level athlete. Through a combination of the tutelage of Stick and self-training, Daredevil is a master of a unique martial art form, which is a hybridized form of American boxing and the Japanese arts of ninjutsu, judo and aiki-jujutsu. Martial arts training has given him an immense degree of concentration and personal control over his body and energy, or Ki.
