-Guysack

Pilots: ---

    Like the Command Wolf, Guysack is seen commonly among bandits, making it a readily available Zoid on the black market. These are some of the most frequently abandoned Zoids that were left behind as sleepers by the Republican Army, when they pulled out of certain lands. Because these Zoids are triggered by tresspassing, they are frequently regarded as a threat, and captured by those who wish to reuse the now-unregistered Zoids for criminal use. Standard Issue is brown.

- Bowl's Guysack

Pilots: Bowl

    Bowl is a pilot that appears in the first episode of Zoids. His Guysack is a custom painted blue one, but is noted to be an extremely low class Zoid. While it seems to do ok picking on a human, Bowl is determined to use this Zoid to prove his skill, in order to obtain an upgrade.

    It is indicated in the first episode that Bowl's Guysack was a Wild Zoid that was captured, instead of purchased or gifted. It was likely a sleeper Zoid left behind from the war, found near the Elemia Ruins.

- Guysack SS

Pilots: Stinger, Dennis

    "Stinger Special"
    Stinger's customized Guysack.

    The Guysack SS is the first customized Zoid seen to be used by Stinger. It is fast, efficient, and piloted better than most that you'll see throughout the entire series.

    It's not just a unique color, either. The Guysack SS has had the tail gun modified to launch a cartridge that, upon impact, will release a fast spreading toxic gas that'll cause paralysis in opposing pilots. This gas can travel very easily through poorly insolated cockpits and works within a minute. It is said to last for over an hour.
