Here is a more detailed profile on the immensly powerful Toa of Lightning.
About this creation
A powerful warrior that few can surpass, Toa Leithe wields a divine lightning staff sent from Mata-Nui, himself. It is said that Toa Leithe went into the Great Temple of Ga-Metru as a matoran, and came out as a Toa Netra wielding a holy staff.
With this staff, no evil can get close to him for fear of its holy barrier.It can fire intense bursts of lightning and can summon massive storms, capable of vaporizing entire mountains. It could vanquish even Makuta if taken off guard. While Toa Leithe is a force to be reckoned with, he is still very young and still has much to learn. He is not very patient and has been known to jump into situations without thinking.
Toa Netra, Phase one: Enhanced armor and weapon. Slight physical change to resemble that of a Toa Nuva.
Phase two: Physical improvement: mastery over lightning invokes staff to reveal its true form.
