Bitsy was an artillery laser cannon that was mounted atop the Moomo Williwaw, a Pelagia Duplex Command Assault Gunship owned by the Moomo Brothers at the time of the Mandalorian Wars. Millennia later in the Republic Dark Age, the cannon was recovered and used by the mercenary force Rusher's Brigade. The Brigade deployed the weapon in 1032 BBY, during an attack on the city Calimondretta, on the planet Syned.
