The Gogg is
Zeon's
first mass-produced amphibious
mobile suit.
Like the later models in the series, it's a squat, monstrous machine with thick pressure-resistant
armor
and multi-segmented arms tipped with sharp claws. The water-cooled
reactor
housed within the Gogg's hulking torso is large enough to power a pair of built-in
mega particle cannons.
However, the Gogg can only operate for short periods out of the water.
