10. This Minigun
Where You've Seen It: Predator & Terminator 2: Judgement Day This massive handheld cannon first appeared in the 1987 action classic Predator, starring Arnold Schwarzenegger. It was the weapon of choice of Jesse Ventura's Blaine, and has since become a staple of video game arsenals everywhere. If you're not familiar with it, it's basically a detached helicopter cannon capable of firing up to 6,000 rounds per minute. The name minigun is ironic, because it's an awesome piece of machinery us mere mortals couldn't even pick up, let alone fire at aliens. Its second usage was in another Schwarzenegger gem, this one being Terminator 2: Judgement Day. In what's still to this day arguably Arnie's best work, the minigun is used by the Terminator to keep the police at bay, obliterating several cop cars in the process. While there have been many miniguns used in movies since, these have been confirmed to be one in the same, and we're going to assume that Arnold now has thing monstrosity from his living room ceiling or something equally garish in accordance with his personality.
