Brain Bleacher
Formally, the Cerebellar Holographic Mnemonic Re-Encoding Induction System, more commonly known as 'brain bleach,' this device loosely resembles, and is about the same size of, a conventional smart phone, which is a useful camouflage.
This is the "forget it all" device. Multiple options for its use render it highly adaptable to various situations. These include the wholesale wiping of memories, and the ability to substitute one pre-programmed 'memory' for another, as well as to make up a new 'memory' on the fly. The original memories are recorded in the device's own memory chip for later archiving at Headquarters, so if it is desired to recover the memory for the individual, it can be re-downloaded.
