Polibra craft small pots from river mud, carefully filling the pots with water from their home river. During battle, they wield the water from their pot as a weapon, controlling the liquid with their psionic powers.

It is rumored that a boy with psychic abilities suddenly transformed into Polibra while he was assisting research into extrasensory powers. Its highly developed muscles never grow fatigued, however much it exercises.
