Slither vines were a bioengineered Imperial weapon created on the planet Setron.
Originally created on the planet Setron in an Imperial laboratory, slither vines hung from places such as ceilings or trees. Slither vines would react to touch but would become more aggressive if shot at by blasters. Slither vines could survive in the jungle, inside the ruins of the laboratory, and underwater.
Originally created in an Imperial medical laboratory overseen by Doctor Royce Hemlock, the slither vines were engineered to be an Imperial weapon. However, when the Empire lost control of the vines, they evacuated and ordered a Base Delta Zero on their facility, orbitally bombarding the base with the intent of wiping out the slither vines. Instead, they survived and grew in the ruins of the facility and into the surrounding jungle.
Around 18 BBY, the Bad Batch traveled to Setron in search of the laboratory, where they believed their comrade Omega was being held. They met the clone cadets Deke and Stak, who decided to lead them back to their camp in hopes of helping the two clones get information. En route, Wrecker brushed up against a slither vine and was attacked, although Hunter was able to slice off the vine with his knife.
Upon learning the reason for their visit, Deke offered to take Hunter and Wrecker to the facility to collect information regarding the Empire's experiments and Omega's location. As they did so, slither vines attacked them and their ship. A particularly large vine attempted to eat the group, using its vines to grapple onto the ship, but was killed after a large amount of explosives were dropped through its mouth.
