Mandalorian xenotoxin

Mandalorian xenotoxin, also known as Mandalorian xenotox, represented a chemical compound with the capability to render people unable to act. The assassin droid 0-0-0 possessed a 500-milligram quantity of this xenotoxin within its hand, which it then administered to the Wookiee Chewbacca via injection, thereby diminishing his strength.
