Marvel: Danger Detection

Heather Cameron (Lifeguard)
She has the ability to register danger to human life in the vicinity, and this automatically gives her the powers necesarry to save those lives, be they her own or others.

Johnathon Gallo (Ricochet)
Ricochet's mutant powers also give him a "danger sense", that functions much like Spider-Man's "spider-sense", allowing him to sense danger before it happens.

Peter Parker (Spider-Man)
Spider-Man possesses an extrasensory "danger" or "spider" sense which warns him of potential immediate danger by the manifestation of a tingling sensation in the back of his skull, and links with his superhuman kinesthetics, enabling him to evade most any injuries, unless he cognitively overrides his automatic reflexes. The precise nature of this sense is unknown, though the Master Weaver states it is enabled by his connection to the Web of Life and Destiny. It appears to be a simultaneous clairvoyant response to a wide variety of phenomena (everything from falling safes to speeding bullets to thrown punches), which has given several hundredths of a second warning, which is sufficient time for his reflexes to allow him to avoid injury. The sense also can create a general response on the order of several minutes: he cannot discern the nature of the threat by the sensation. He can, however, discern the severity of the danger by the strength of his response to it. Spider-Man's spider-sense is directional and can guide him to or away from hidden weapons and enemies.Sudden and extreme threats can cause his spider-sense to react with painful intensity. Spider-Man can also sense and dodge attacks directed randomly or by an artificial intelligence. Using his spider-sense to time his enhanced reflexes, Spider-Man can casually dodge attacks up to and including automatic-weapons fire, provided there is sufficient distance. His spider-sense is sufficiently well-linked to his reflexes to the point that a threat can trigger them even when Spider-Man is asleep or stunned. His spider-sense has helped him preserve his secret identity since it alerts him to observers or cameras when changing into or out of his costume. The spider-sense does react to those who Spider-Man does not consider to be a threat, such as Aunt May. Spider-Man can choose to ignore his spider-sense, and distraction or fatigue diminish its effectiveness. Spider-Man's fighting style incorporates the advantage that his "spider-sense" provides him. His body begins to produce more adrenaline after the sense is triggered, an extension of the 'fight or flight syndrome.' Even when he does not have the use of his eyes, Spider-Man can still use his Spider Sense in a similar fashion to Daredevil's Radar Sense to help him see by sensing the direction the danger is coming from by listening on the loudest noise around him. This was first used after Spider-Man was temporarily blinded by a device but was recently used again to help locate the new Vulture after his acidic breath blinded him. While he temporarily lost it during his battle with the Spider-Slayers, it was restored during the Spider-Island story-line.
