To start off with Qubik was no more than Nobrocybix’s ultra high-tech portable stereo. But of course he couldn't help making improvements to it, which ended up with him equipping Qubik with an artificial intelligence that made him able to mix as well as any human (fortunately DJ Korr is no ordinary human )... And the sonic cannons are just a little added bonus for when the Junkz get into trouble.
