Creatinine, a compound identified in the blood work of the Trandoshan individual Nack Movers, was discovered following his murder via sennari poison. This analysis was conducted by the Coruscant Security Force crime scene analysis droid Russo-ISC in 7958 C.R.C.. The level of creatinine detected in Movers's blood was 130, a quantity that the droid determined was not a pollutant.
The substance creatinine initially appeared in the 2018 publication titled Star Wars: Scum and Villainy: Case Files on the Galaxy's Most Notorious, authored by Pablo Hidalgo.
