Spider-Sense

Spider-Sense is one of Spider-Man's most unique and prominent powers. The power itself originates as a tingling feeling at the base of his brain.

History
Spider-Sense presents a psychological awareness of Spider-Man's surroundings. It warns Spider-Man of danger if detected before it happens in no time at all. The greater the danger or how close the danger is increases the tingling sensation. It also allows Spider-Man to navigate when unable to see, hear, or if he's disoriented. It also helps Spider-Man fire his webshooters without having to concentrate every time he does so, greatly helping his ability to swing through the city. Spider-Sense is retrocognitive in nature and Spider-Man of always acts before realizing it. The tingling gets stronger when the danger becomes more imminent and more threatening and Peter finds out where the danger is coming from and how to avoid it.

Thanks to his Spider-Sense, Spider-Man can dodge physical attacks, laser blasts, weaponry, and even explosions. Spider-Man has also been known to use his ability to find hidden objects such as passageways. When Spider-Man fought The Spot he used his Spider-Sense to figure out which portal would allow him to hurt the Spot. It also warns Spider-Man when someone is watching him when he is about to change into either Spider-Man or back into Peter Parker.

Spider-Sense allows Spider-Man to physically fight those who have had more training than he. In fact Spider-Man has had little to no combat training. But he has still managed to fight those like the Punisher, Blade, and Wolverine.

Although Spider-Sense does not manifest itself outwardly it can cause Spider-Man to do so. When Peter's Spider-Sense goes off Jason Phillips, seeing Peter react physically, asks him if something is wrong.

Spider-Man sometimes ignores his Spider-Sense. Green Goblin once found out his identity because Spider-Man thought his Spider-Sense was acting up instead of warning him. Sometimes his Spider-Sense does not go off because he is fatigued or distracted. Spider-Man once got caught in an explosion because he is focusing on Alistair Smythe who just kidnapped Black Cat.

Spider-Sense does not go off to those that Spider-Sense does not believe to be a threat. It will not go off for Aunt May or Mary Jane Watson. But it has been known to go off to those that Peter does not think to be a threat but really is, such as when Chameleon disguised himself as Anna Watson or when Peter met Jason Phillips who was not yet revealed to be Hobgoblin.

Venom, Carnage and Madame Web are completely undetectable to his Spider-Sense.
