On this week's episode of CNBC's "Jay Leno's Garage," the late-night legend pilots a real-life, futuristic MegaBot and battles an oven. Frankly, the kitchen appliance never stood a chance. The 15-foot, 15-ton robot fighter is equipped with weapons for hands. Plus, it's powered by a 430-horsepower Chevy V8 engine, making for the "most over-the-top use" of one Leno says he has ever seen. "This is a classic example of, 'Absolute power corrupts absolutely,'" he says, before nearly striking himself in his robo-face with his robo-claw.

"Hey, Jay, can you just hold off here for a second?" says MegaBot co-founder and backseat driver Matt Oehrlein. But it's too late. Absolute power has corrupted absolutely. Leno grabs an oven, shakes it like a schoolyard bully robbing a smaller kid of his lunch money and throws it down. Then he bellows out an evil laugh fit for a Bond villain. "If our country is ever attacked by an oven, boy, this is the machine you want to have," he says.

Mechanical engineer Gui Cavalcanti originally founded MegaBots alongside Oehrlein, an electrical engineer, and Andrew Stroup, a builder, in 2014, with the dream of making the kind of over-sized robot fighters you see in video games or films in which they befriend Shia LaBeouf. "We're trying to blend Formula One and UFC," Cavalcanti tells Leno, who describes the MegaBot shop as "where really big dreams, and really big nerds, come to life." Last year MegaBot's Eagle Prime battled the Japanese robot Kuratas, built by Suidobashi Heavy Industry, in a much-anticipated duel that some critics found ultimately underwhelming. "MegaBots is like if BattleBots took an Ambien," wrote Quartz.
