XXX-01EN Earthquake Naga Gundam

""

XXX-01EN Earthquake Naga Gundam is a unit of uncertain providence. Having been recovered in a collection of confiscated parts and gear by the EFA, it was immediately considered infeasible to actually deploy because the nonstandard 'leg' system had to be manually controlled at all times. Only the development of the S-Type cybernetic control device, which allowed the user to synchronize part of their brain with their machine, allowed it to be controlled correctly - but because it would require the user to mentally convince themselves that they had no legs, it was still considered unlikely to be used seriously. That changed when Fern Calico, who had recently recieved a modified S-Type cybernetic control device, was able to use it as her own.
