Hyperflux Cannon

Pull my finger.

As the Hyperflux Cannon charges up, its spinning vortex collects energy straight from the cosmos, with the vortex generating a heat shield that protects its user against incoming fire. Worse yet, when the cannon actually fires, its blast can create miniature black holes that completely destroy whatever target is unfortunate enough to be hit by it. A terrifyingly powerful weapon, it is of course only logical that a Decepticon scientist like Shockwave would have the Hyperflux Cannon as his left forearm.

Fiction

Spinning makes everything better.

• Shockwave (Voyager, 2013)
  • Series / Number: 02 / 003
  • Accessories: Chest armor panel, 2 shoulder/foot armor panels

Part of the second wave of Prime: Beast Hunters Voyager Class toys, Shockwave has a permanently attached "Hyperflux Cannon" as his left forearm. By repeatedly pressing down on the trigger on top of the cannon, the barrel of the cannon spins while opening and closing, revealing more of its translucent red tip, giving the impression that it's glowing/charging. The left tread on his backpack unfurls and connects to the cannon to act as a hose.
