Espers

Espers are humans that naturally awaken, possess and can harness psychic powers. Natural Espers are quite rare, but once awakened can become quite powerful in their own right.

Powers and Abilities
Upon awakening 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, such as raising a defensive barrier and attacking, simultaneously; however, with enough skill and effort, it is possible to do so.

While simple telekinesis seems to be the default ability Espers are born with, many Espers have developed and specialised the way they utilise their powers, meaning most possess abilities and techniques unique to themselves (at the cost of only being able to perform said 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 Touichirou Suzuki.

Notes and Trivia

 * While numerous Espers have been introduced, until Mob met Teruki Hanazawa, he had not encountered any others besides himself.
 * It is unknown what causes an Esper to awaken, as Mob awakened many years before his brother did.
 * 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.
