Lets talk about Mega Man ZX NDS

In Mega Man ZX, hundreds of years have passed since the battles between
humans and Reploids (robots). After fierce wars between the two sides, peace was
finally restored and the two groups were able to establish various cooperative
nations within the “Inner” area of the universe. However, danger zones remained
in the undeveloped “Outer” section where independently evolved robots called
“Mavericks” began wreaking havoc. A group called the Serpent Company scours the
Outer universe to provide energy created from otherwise unattainable items to
the Inner population and also serves to protect these peaceful nations from
Maverick attacks over the years. On an excursion to the Outer region, they
discover relics of ancient technologies in the ruins. These relics, called
Biometals, are living, conscious materials, with records of information and
weapon data from history housed within.
