Spore

This ancient entity was imprisoned 400 years before the Galactic Civil War in an asteroid by the Ithorians. Spore was a genetic construct of Ithorian botanists, who had hoped to merge the DNA of a vesuvague tree and a Bafforr tree with other material to create a sentient plant. Instead, they created an evil creature which needed more minds to expand its thoughts and work its damage. It could use the minds of almost any living creature to augment its own power, and it was thought that Spore could control several thousand minds at one time. With the help of the Jedi Knights, it still took over 100 years for the Ithorians to capture and neutralize Spore, entombing the entity in an asteroid where is was forced into dormancy by the hard vacuum of space. The Ithorians could not kill Spore, because of their adherence to the Law of Life. When Mining Station Alpha was established on the asteroid to collect minerals, the Ithorians carefully monitored their progress, lest they discovered Spore's tomb. Unfortunately, the tomb was discovered by Hodge and his team shortly after the Battle of Yavin. Spore was released, and the ripples of evil permeated the Force. Emperor Palpatine sent the Dark Jedi Jerec to capture Spore, but the entity had already escaped its prison and hidden itself in the body of the mining chief Hodge. Fandomar was livid with fear, and rushed to escape the asteroid before Spore could infect anyone, but she was too late. She brought Hodge - and Spore - back to Ithor, and Spore attacked the rescue party that came to find them. Black vines snaked out from Hodge's mouth and eyes, entwining the Ithorians and threatening to capture Hoole. Each vine that touched a being infected it immediately, including the Shi'ido Hoole, and Spore raced to infect the Tafanda Bay. Jerec then intercepted Spore on Ithor, and offered it the chance to get off the planet if it would infect the crew of the Vengeance and make them his slaves. Spore agreed, but had no intentions of helping Jerec for very long. Spore tried to capture Tash and Fandomar, but a group of space slugs smashed the Vengeance, dropping her shields and causing it to explode. Spore was split into a thousand small pieces and neutralized in the vacuum of space.
