Neziregia

Neziregia is an alternate dimension which exists within the world of Denji Sentai Megaranger. It is ruled by Evil Electro-King Javious I.

It is unknown how Neziregia came into existence, considering the circumstances by which it does exist. The dimension itself is in actuality a zone completely filled and created by Nezire Energy, the source of which is the "Javious Heart" within the Death Neziros spacecraft. The dimension completely surrounds the Death Neziros, with Nezire Energy surrounding it.

Aside from Javious, who appeared to be a being who ruled the dimension like a god but was actually completely locked within the Death Neziros unknowingly, many other creatures were born or created within the space as if their own lifeforms. All of the Kunekune are beings created from the Nezire Energy, as are more complex lifeforms such as the monstrous Guirail.

In order to gain the means to conquer the dimension of Earth, Javious lures scientist Professor Samejima from the company known as I.N.E.T. into this world, unknowing of the scientists own ambitions and desires for control. Rechristiening himself as Dr. Hinelar, the scientist became the commander of Neziregia's forces but began performing his own experiments as he used his mind to discover the truth behind the dimension. Ultimately learning the truth of the Javious Heart within the Death Neziros, Hinelar creates his Jaden Sentai Neziranger as a means to both combat the Megaranger created by I.N.E.T. after his departure and to drain his master of energy. When the Neziranger are completely destroyed, Javious dies and likewise Neziregia is completely destroyed, with all remaining Nezire Energy within the Javious Heart and within Hinelar's hands as the ship heads to Earth.
