Signature mobile suit of the Principality of Zeon in all Universal Century-era Gundam media. Recognizable by its green paint job and eerie single red camera-eye. It's almost as much of a mascot for the series as the original Gundam MS is.

Most other Zeon mobile suits share at least some of the Zaku's design DNA, but most notably the Gouf.

"This is no Zaku, boy, no Zaku!"
