Anti-clone viruses were theoretical ailments that the CIS were allegedly creating throughout the Clone Wars. The Galactic Republic's clone trooper Tup killed Jedi General Tiplar in the midst of the Battle of Ringo Vinda, and his evident memory loss regarding the event perplexed both the Jedi and clones, leading them to consider the chance that his behavior was potentially due to a virus, a poison, or some form of illness. General Tiplee, a Jedi, suggested that an anti-clone virus was a potential explanation. The reality was that Tup's behavior stemmed from a defective inhibitor chip, a biological mechanism placed within each clone soldier to guarantee their obedience in carrying out the Jedi's demise during Order 66.
