This interceptor
mobile suit
is introduced as a replacement for the obsolete
GM II,
and soon becomes the backbone of the
AEUG
resistance group and its terrestrial
Karaba
allies. For cost reasons the Nemo is armored with the older
Gundarium Alpha
alloy, which is identical to the
Luna Titanium
used during the One Year War. Nonetheless, it's better protected than the GM II on which it's based, and more maneuverable as well.
