Octuptarra combat tri-droid

The Octuptarra combat tri-droids were advanced combat automata used by the Techno Union and the Confederacy of Independent Systems during the Clone Wars.

The stilt-legged spider-like automatons had large balloon-like heads atop their thin stalk bodies, armed with laser turrets. They were named after the eight-eyed gasbag-headed vine walkers native to Skako.

They were standardly equipped with three laser turrets, one one each side, below each photoreceptor. A certain variant was filled with a gaseous virus that would be released upon the droids' destruction. The virus variant were nicknamed "virus droids".

Their rotating multi-jointed assemblies allowed them to change facing almost instantly and they could fire from extended ranges, though they were vulnerable in close-quarters fighting. It was almost impossible to destroy such droids, as all sides conceivably faced the front.

The octuptarra was a smaller cousin of the tri-droid, which was used by the Separatists in campaigns on Mygeeto.

During the Second Battle of Coruscant, a group of octuptarra tri-droids used laser beam cannons against Jedi Masters Mace Windu and Yoda. The beams could be maintained, similar to the OG-9 homing spider droid's turret, so the Jedi were able to destroy several tri-droids with one beam by deflecting it with their lightsabers.

Following the execution of the Separatist Council by Darth Sidious's new apprentice, Darth Vader, these units were de-activated, although they remained a common sight on some worlds like Uba IV.

Trivia
These droids fired yellow bolts, a rarity in Star Wars canon.
