Espers

The Espers (超能力者, Chō nōryoku-sha, lit "Psychic") are humans that naturally awaken, possess and can harness Psychic Powers (超能力, Chō nōryoku). Natural Espers are quite rare, but once awakened, they can become quite powerful in their own right.

Powers and Abilities
Upon awakening, most Espers possess the natural abilities to utilise, allowing them to manipulate things with their mind. They all have the basic ability to see Spirits, sense others with psychic power and also create a protective barrier around themselves. Almost no Esper can perform two actions simultaneously, such as raising a defensive barrier and attacking, however, with enough skill and effort, it is possible to do so.

While simple telekinesis seems to be the default ability many Espers are born with, some Espers have their own unique abilities. They developed and specialised the way they utilise their powers, meaning most possess applied abilities and techniques unique to themselves (at the cost of only being able to perform said applied ability/technique). However, skilled Espers are able to learn, copy and perform a multitude of psychic abilities and techniques as shown by Teruki Hanazawa and Toichiro Suzuki.

Notes and Trivia

 * While numerous Espers have been introduced, until Mob met Teruki Hanazawa, he had not encountered any others besides himself.
 * Although stated in canon that Esper powers are awakened by stress, or rather 'heightened emotions', some are simply born with it (at birth) rather being awakened at a later time. The likes of such are Keiji Mogami, Toichiro Suzuki, Ryo Shimazaki and Shigeo.
 * From the experiments Claw performed, it can be assumed that any human can potentially become an Esper. However, via the questionably brutal methods Claw used, artificially awakened Espers either went insane after awakening or received extremely weak powers.
