Kenbunshoku Haki, also known as Mantra on Skypiea, is a form of Haki that allows the user to sense the presence of others, even if they are concealed from view or too far to see naturally. With enough skill, one can use this Haki to predict an opponent's moves shortly before they make them, thereby making the attack that much easier to evade. This prediction appears to the user as an image or brief "premonition" of what the opponent will do in the user's mind's eye, and the damage the user will take if the attack actually "hits". It appears that the more killing intent the enemy has, the easier they are to predict. Although, more skilled users can predict future moves whether there are ambient murderous intents or not.It was first introduced under the name Mantra when Satori used it to fight Sanji, Luffy, and Usopp as they went through the Ordeal of Balls. Aisa is the only known Shandian who has this ability. It served as a plot point when she helped Luffy locate Enel. It varied in strength between users, with Enel's seemingly being the strongest. With his Devil Fruit, the Goro Goro no Mi, Enel could pick up electromagnetic waves, allowing him to overhear conversations and everything around him; this extended the range of his Mantra to cover roughly all of Skypiea. By comparison, most of the other priests could only keep track of people nearby.The first time it was seen being used and referred to as Haki was during Luffy's battle on Amazon Lily with the Boa Sisters. Later, Rayleigh explained Haki to Luffy and confirmed that "Mantra" is the Skypiean name for the ability.
Though the power allows the user to predict most attacks, it can be circumvented by various means. It cannot predict inherently random attacks; for example, Luffy managed to bypass Enel's Mantra by bouncing his fists off a nearby wall, to prevent himself and thus Enel from knowing where they would land. Tying in with the inability to detect random attacks, Kenbunshoku Haki seems to be linked to the target's own awareness of themselves and their surroundings. Enel failed to discern the presence of Luffy inside the giant snake Nola, only detecting him after he escaped. Similarly, Aisa could not detect how the battle was progressing with her Mantra while inside Nola and only found out what happened after she and Luffy escaped. It also does not make the user any faster than normal, so the user's ability to dodge is dependent on their speed; Enel was unable to avoid Luffy's finishing move because it was moving too fast, even though he was able to predict it. Likewise, Luffy's Gear Second was able to outpace Boa Sandersonia, despite her ability to read his moves. It also seems to falter if the user loses their concentration. Satori lost the control of his Mantra when Luffy unexpectedly brought the string of exploding balls right to him, enabling Luffy to grab him from behind when the smoke cleared, and Gedatsu lost to Chopper because he lost his concentration and his Mantra faltered.
This type of Haki can also allow to user to sense the emotions and nature of others. For example, Otohime used this Haki to sense sense the sufferings and emotions in the heart of a fishman thief and Aisa was able to sense Wiper's aggressive nature with this Haki.
It appears it's also possible for the user of this Haki to sense the strength of others as well. This was shown when Rayleigh used this Haki to sense that there were 500 creatures on Rusukaina who were stronger than Luffy at that time.
Spider-Man's "spider-sense" manifests in a tingling feeling at the base of his skull, alerting him to personal danger in proportion to the severity of that danger. For instance, a little tingling such as a happenstance passing by of an enemy would prompt Peter to be alert, while a strong tingling, sometimes to the point of being painful, is interpreted as a need to take immediate evasive action on a deadly threat. It appears to be a simultaneous, seemingly clairvoyant response to a wide variety of phenomena. Though the exact mechanism of this ability is unknown, (though in The Amazing Spider-Man #1, he refers to it as an instinctive ability) his original spider-sense clearly has at least two aspects in addition to sensing potential or immediate danger:
- A psychological awareness of his surroundings, similar to the radar-sense of Daredevil. When he is temporarily blinded, Spider-Man learns to emulate this ability and navigate without his eyesight. Even under normal conditions, his spider-sense helps him navigate darkened rooms, instinctively avoiding obstacles or hazards, or potentially noisy or unstable floorboards, walls or ceilings that may betray his presence. In one comic, he is shown sensing how many fingers Mary Jane is holding up.
- An ability to detect certain radio frequencies. Spider-Man's technical skill is such that he has designed spider-tracers that broadcast a signal detectable by his spider-sense.
Using his spider-sense to time his enhanced reflexes, Spider-Man can casually dodge attacks up to and including automatic-weapons fire. Even point blank, his spider-sense has already warned him in enough time to get away like a precognitive sense, before he can even consciously think about his actions. However, he can ignore this instinct. His spider-sense is sufficiently well-linked to his reflexes, even before "The Other" storyline, that a threat can trigger them even when Spider-Man is asleep or stunned, as in The Amazing Spider-Man #141, where a narcotic gas released by foe Mysterio caused him to lose his balance and fall from a building. Though barely conscious, a combination of spider-sense and reflex caused his arm to seize a fire-escape ladder, saving his life.
When Spider-Man swings across a city on his weblines, his spider-sense guides his aim, allowing him to travel at high speeds hundreds of feet above street level with minimal concentration, confident his weblines will find secure anchor points.
Spider-Man's spider-sense is directional and can guide him to or away from hidden weapons and disguised enemies. Sudden and extreme threats (such as the Beyonder observing Earth before the first Secret Wars, Thanos using the Infinity Gauntlet to destroy half of the sapient population of the universe, the Ultimate version of Venom, or the predatory Morlun) can cause his spider-sense to react with painful intensity.
Spider-Man can also sense and dodge attacks directed randomly or by a computer. 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 not react to those whom Peter does not consider a threat, such as Aunt May. Contrary to this, his spider-sense has warned him of people close to him when he does not wish to be seen, such as when he's partly in costume.
Spider-Man can choose to ignore his spider-sense, and distraction or fatigue can force unawareness.
Spider-Man has used his spider-sense to battle even the most skilled fighters in the Marvel Universe. While not being as trained as them in conventional fighting styles his spider-sense and reflexes (provided with split second quickness and agility) allow him to dodge and counter, often with ease.
After the "Disassembled" and "The Other" storylines, Spider-Man gains the ability to feel vibrations and currents in the air or in his web lines, much like a real spider. He also develops a psychic connection to insects, spiders, and other arthropods, though this aspect of his powers may no longer be present (see below). The spider-sense also allows Spider-man to determine the source of the incoming attack, which gives him an advantage against enemies who are all over the place like Spot.
As a result of the storyline "Revenge of the Spider-Slayer", Spider-Man loses his spider-sense when he sets off a device that disabled Spencer Smythe's latest creations' ability to coordinate their attacks via a similar principle. As such, he starts taking kung-fu lessons from Shang-Chi, on Madame Web's advice. When his full powers are restored in the "Spider-Island" storyline, his battle-honed body granted him a new, refined form of Spider-Sense that allows him to draw upon Shang-Chi's training instead of automatically reacting to threats.
