Meteor Blaster

From Brickipedia, the LEGO Wiki

Meteor blasters are a weapon used by all hero factory villians except 7145 Von Nebula. They are similar to thornax launchers from BIONICLE, but they are black instead of silver, and fire green zamor spheres (the exception is 7162 Rotor, who has an orange laucher).
