The Geno Saurer is a Tyrannosaurus-type Zoid, created by the Guylos Empire, and used during the Helic-Guylos wars that occurred on Zi after the meteor strike of ZAC 2056.
The Geno Saurer was one of the first new Zoids designed after the destruction of the third moon of Zi and the resulting meteor shower. The Zoid's design came about by scaling down the Death Saurer, and adapting its technology. Geno Saurers were the first Zoids to be equipped with the newly-developed Organoid System. This system, derived from technology found in an ancient ruin, enhances the Zoid's intelligence and abilities.
The Geno Saurer is a very capable Zoid, being fast and agile, while also very well armed and armoured. The Zoid's main weapon is a Charged Particle Cannon, a derivative of the Death Saurer's main weapon. While smaller and less powerful than the older weapon, the Geno Saurer's cannon remains potent. The Zoid's only weakness is that it needs to be anchored and completely stationary in order to fire the Charged Particle Cannon. Another problem is caused due to the massive heat generated by such a weapon, causing the weapon to only be able to fire once every couple of minutes. The thick tail of the Geno Saurer is covered with vents and filled with heat-sinks to partially compensate for this problem.
In the anime and the games, the Geno Saurer (as well as the Geno Breaker) is depicted with an additional weapon. It is able to launch its hands on long, retractable cables like grappling hooks to grab and restrain Zoids at a distance, and pull them into its line of fire. In addition, these "grappling claws" can deliver an electric shock, though it loses the ability to shock opponents when it becomes the Geno Breaker
