Name: Gunzoo (ghun zu)
Height: 1.8
Mass: 800 lbs
Homeworld: Believed to be SR388

During their brief settlement of SR388, the Chozo created a series of automatons to make their daily lives easier, to keep them company, to difficult or dangerous work, and to guard and defend important sites and buildings. When the Chozo were forced to leave SR388 most of these automatons were left behind.

Some of them deteriorated beyond repair while other continued their original programming or simply kept functioning without a purpose at all, becoming a hazard for the life of SR388 or any unfortunate visitor who might stumble on these machines. The Gunzoo is an enigma to the scientists of the Galactic Federation who studied the various ancient Chozo robot designs that were found on the world of SR388. Although the Chozo were definitely capable of designing and making machines for the sole purpose of conflict, there was never any mention of a period in their Empire's centuries long existence for any need for such devices. Although the Chozo had a proud warrior order, there was no known force at that time that could truly match the strength of the Chozo. Not even the then already present Space Pirate Legions posed such a threat that the need for a dedicated automated war droid was there.

Most of the Chozo's droids with weaponry were used for security tasks when some form of aggression was needed such as the ‘Wallfire' or ‘Autrack'; the Gunzoo on the other hand is designed primarily for offensive battles. Instead of just guarding a pre-programmed corridor or area, the Gunzoo actively searches for life forms, which it then engages with its multiple weapon systems. This is a radical departure from the Chozo's ideology of peaceful existence; only believing that violence was needed when their people were threatened. And then only if no other solution was possible. Yet the Gunzoo droid design proves that there was something on SR388, which forced the Chozo to use their knowledge to create, dedicated combat robots in order to combat this threat.

The Gunzoo itself is a powerful automated weapons platform, equipped with a sophisticated droid AI and a power anti gravity drive system, which gives it excellent mobility. It is equipped with various weapon systems such as plasma cannons and flamethrowers. Although its armor is not strong as that of the Autom, the Gunzoo is one of the more powerful left over droids on SR388. Current Federation weaponry is capable of damaging and destroying a Gunzoo, but caution is suggested when in the vicinity of a Gunzoo unit, and Galactic Federation Police are warned to avoid rather than engage a Gunzoo if possible.

Note: Since the X-Incident, Federation scientists have suggested the theory that the Gunzoo was the Chozo’s earliest response against the growing X threat before they created the lifeform known as Metroid.
