Description

Two BrickHeadz, one famous stand-off

40631 recreates one of the most quoted moments in The Lord of the Rings, Gandalf's confrontation with the Balrog, in LEGO's chunky BrickHeadz style rather than as minifigure-scale scenery. Building two figures instead of one gives the set a bit more presence than a standard single-character BrickHeadz box, and it invites builders to display the pair together rather than separately. At 348 pieces the build is substantial for the format, since BrickHeadz sets are normally built from far fewer pieces than this.

No minifigures, all character

Unlike most Lord of the Rings sets in the wider LEGO range, 40631 comes without any minifigures at all, putting the full focus on the two oversized BrickHeadz heads and bodies. That makes it a set for collectors of the BrickHeadz line specifically, or fans who want Gandalf and the Balrog as a stylised display piece rather than as playable figures alongside a fellowship set. It's a reminder that BrickHeadz trades screen-accurate scale for a big-headed, cartoonish likeness built purely for the shelf.

Fire, stone and shadow in one palette

Black and light bluish grey form the bulk of both figures, covering Gandalf's robes and the Balrog's rocky, shadowed form, while dark bluish grey adds depth to the stonework details shared between the two builds. Red stands out as the Balrog's fire, the one warm colour against an otherwise cold, grey-toned pairing, and it's what makes the demon instantly recognisable next to the wizard beside it.

108 unique parts behind the pair

With 108 unique parts across 348 pieces, the set relies on plenty of specialised BrickHeadz shaping — the signature square heads, hands and stud-and-tube joints — alongside smaller detail pieces for robes, flames and rock texture. The parts list on this page runs through both figures individually, useful for checking exactly which elements go into Gandalf and which build the Balrog, or for spotting pieces that might suit other fantasy-themed projects.
