Last year, Nerf released its Rival Nemesis MXVII-10K, a 100-round, full-auto ball-blaster that took Nerf's high-speed Rival line to its most freakishly fun extremes. This year, just ahead of Toy Fair 2018, Nerf showed Popular Mechanics its new contender for top dog when it comes to positively dumping the foam on your friends and frenemies. Here's your first look at the beautifully bonkers Nerf Rival Prometheus MXVIII-20K.

Like the before it, Prometheus fires Nerf's spherical yellow Rival rounds at speeds of up to 70 mph or 102 feet per second out of the barrel. Unlike its predecessor, the Prometheus sports a 200-round hopper as well as an 'advanced acceleration system' that can put balls on the bulls-eye as fast as eight per second, much faster than any other Rival blaster so far. Believe you me, it is a downright bewildering pace. In our tests with a prototype unit, I went through 200 rounds in 36 seconds, or 5.5 rounds per second on average:

The Prometheus is battery-powered with an built-in battery that connects via a wall charger, unlike the Nemesis which supports replaceable battery packs. At $200, it's a pricey proposition, but you've never seen anything quite as intimidating—or thrilling to fire—than this frankly overkill bad boy. Short of building something yourself, you'll be hard-pressed to find anything closer to a fire hose for foam.

NERF RIVAL PHANTOM CORPS HADES XVIII-6000

In addition to the Prometheus, there's also the new Rival Phantom Corps Hades XVII-6000, a high-capacity single-fire blaster for the more conservative marksman. With room for 60 rounds, the Hades is the bigger brother of the smaller and packs a slow but serious punch. It may not lay down covering fire quite like the Prometheus, but bulls-eyes make a wonderfully satisfying * PUCK * and its internal magazine is ridiculously fun to open and close.

The Hades will retail for $70 and will be available alongside the Prometheus in fall 2018.
