Pick a senario, any senario 😛
The Saix was a good runner, and that made it fairly effective in evading Death Saurers and the larger heaver Zoids, but the Saix had no weapons that could possibly even affect it. the theory was that it made a good behind enemy lines attacker and flank assaults, but not real good in direct assault.
The Zoidians formed the basic blueprints, but never got beyond that stage before the Death Saurer began it's rampage.
