Gandalf the Grey and Balrog Reviews
Brickset
“40631 Gandalf the Grey and Balrog accordingly includes the first LEGO Balrog, although in BrickHeadz form. Nonetheless, the figure appears absolutely unique among BrickHeadz, while Gandalf is the perfect adversary for Durin's Bane. 40631 Gandalf the Grey and Balrog has... More attracted particular attention among the three The Lord of the Rings BrickHeadz packs, primarily because of the Balrog. The figure represents a notable departure from standard BrickHeadz in some respects, but I think the designer has managed to balance any unusual features with the series' customary characteristics.”

“This Balrog Brickheadz is HUGE, thanks to its wingspan and height, and really nails the “flame and shadow” look. We’ve never gotten a Balrog depicted in LEGO Lord of the Rings, so this makes for a great pairing with Gandalf, who faced off on the Bridge of Khazad-dûm in... More Moria,”
