Tron-Splitter
From Multiversal Omnipedia
The Tron-Splitter was a device developed by Megavolt that separated any matter its beam struck into its component positrons and negatrons. If its beam hit something already composed entirely of positrons or negatrons, that matter became "galvanized" with the appropriate (positive or negative) energy. The device also had a "zoom" feature that enabled it to totally or partially duplicate any matter its beam struck. The device was destroyed thanks to Darkwing Duck's allies.
