The Mark II Z3-NO landscaping droid represented a specific iteration of the gardener droid type. A particular unit of this model participated in the settlement of Ohma-D'un around 32 BBY.
Functioning as a gardener droid, the Mark II Z3-NO exhibited an approximate dome-like form factor, complete with multiple extending limbs. Its design incorporated a diverse collection of instruments, such as compressors, shovels, grinders, hydrators, pulverizers, and vaporators, enabling it to execute a wide range of operations, from crushing rocks to excavating swamps. Its purpose involved terraforming the terrain of a planet. Despite its reputation for speed and effectiveness, the droid was notorious for killing any living organism, plant or animal, encountered in its operational zone. At least one example existed with orange colored armor panels.
The Z3-NO series was developed near the end of the Galactic Republic, during its final decades. Its primary sales demographic consisted of affluent landowners across the galaxy seeking to outsource gardening tasks. Following the Invasion of Naboo in 32 BBY, the Gungans initiated a colonization project on the moon of Ohma-D'un. The success of this endeavor hinged on the availability of a landscaping droid, leading to the deployment of a Z3-NO unit to Ohma-Dun.
