LEGO set 70313, Moltor's Lava Smasher, is part of the Nexo Knights theme and depicts a lava themed vehicle connected with Moltor. Released in 2016, it contains 187 pieces and includes 2 minifigures, setting Moltor against Aaron Fox.

Moltor's Lava Smasher belongs to the Nexo Knights setting, where futuristic knights face lava based enemies and monster forces. The model represents a compact attack vehicle for Moltor, giving the villain side a clear buildable presence within the theme’s conflict.

The set is made up of 187 pieces and 2 minifigures listed in the source: Moltor and Aaron Fox with 1 x 2 Plate with Clip on Back. The build focuses on a small action vehicle, using a design language that fits the lava faction rather than a neutral knight vehicle.

It is suited to play scenes, compact display layouts, and collectors who want a representative opponent for Aaron Fox. Within Nexo Knights, it sits as a smaller supporting set, useful for expanding the enemy side and adding variety alongside larger or hero focused models.
