The Three Brothers is a great bad-guy centric addition to your Lego Nexo Knights collection. The vehicle-like monster Rumble is definitely the star of this set. He features a really neat jaw-chomping feature that moves his lower jaw when he rolls forward. As a play feature there are some really nice possibilities here because there is enough space to swallow a good sized item, such as a Nexo Knight in a Battle Suit! Rumble also features a rear-mounted catapult that can sling Gravellers against those pesky knights. The overall model has a really nice chunky design that could carry quite a few minifigures. The build is also very sturdy and can hold up to play without coming apart. The massive front wheels are probably our favourite design choice, as they make Rumble look very intimidating! The little storage compartments for the Gravellers is also a nice little touch, as we're always misplacing those things on our Lego table. The rest of the set is predominantly minifigures, with Axl, Roog, and Reex. Axl is very similar to other iterations in previous sets, but now features some bright orange elements on his armor. He is still as beefy and powerful looking as always! Roog is the coolest of the granite brothers, with his huge stone hands. But both he and Reex have really nice detailing and nice armored shoulder/head elements. Overall a nice set that helps even the balance of power between the baddies and the Nexo Knights.
