Ta'al Pierc was a short, overweight, and middle-aged Human male agent who served the Alliance to Restore the Republic on the planet Toprawa during the Galactic Civil War. He worked for the planet's Imperial Research Station, where he added a program to their systems that would allow a user to bypass the facility's security measures. It was Pierc who informed the Alliance that the control systems for the Death Star's superlaser were being designed on Toprawa.
