This is a gun that can successfully disable and kill any practitioner of alchemy with a Professional Rank or lower.

Po created it in 1955, to disable his granddaughter before she could take over the world. She stole it, and told all who saw it, that SHE created it.

In season six, it came into Mozart's possession after Mandy dropped it, until he lost it in the ocean.
