Pacifista

The Pacifista (パシフィスタ Pashifisuta?) are human weapons (人間兵器 ningen-heiki?) developed by, the currently unknown, Marine head scientist. They are cyborgs, built in various ways. Sometimes by using others as molds, or perhaps making their own, original, design. It's been rumored the funds required for the construction of just one Pacifista are roughly equal to that of a Marine-issued battleship.

Appearence
The only revealed Pacifista so far, Admiral  Alpha appears to look like a normal hedgehog, albeit robotic.
