C-4000 are explosives created by the Hero Factory.
History[]
Merak 9 once received a shipment of C-4000 and the Alpha Team was called in to guard it. They were attacked by XPlode and Rotor under orders from Von Nebula. During the fight, XPlode left Rotor there and William Furno attempted to Hero Cuff Rotor, but Rotor toyed with him until Furno threw his Dual Fire Shooter into his propellers. Rotor then revealed a smaller Meteor Blaster and Preston Stormer shoved him out of the way, and Rotor escaped.
