Espers

An Esper is an individual capable of telepathy and other similar paranormal abilities.

Overview
Espers are individuals of various races that naturally awaken, possess and can harness psychic powers. Espers are quite rare, but once awakened can become quite powerful in their own right.

Geryuganshoop claims to be the strongest psychic combatant in the universe, this is however simply self-proclaimed, as Tatsumaki is currently shown to be the most powerful esper in the entire series.
