Anti-clone virus

"There have been rumors that Separatists have been trying to develop an anti-clone virus&mdash;biological warfare."

- Jedi General Tiplee on what could possibly have caused Tup to murder Tiplar

By the time of the Battle of Ringo Vinda, there had been rumors that Separatists had been attempting to develop an anti-clone virus. When clone trooper Tup of the Galactic Republic murdered Jedi General Tiplar at the height of the battle, his apparent lack of memory of the incident baffled the Jedi and the clones, causing them to speculate that it was possible that his actions could be because of a virus, a toxin, or a type of sickness. Jedi General Tiplee stated that the virus could be a possibility due to rumors of an anti-clone virus.
