BrickEconomy Expert Review
“Ronto the Master Dragon offers a mixed experience, delivering a mid-sized dragon build with four minifigures at a reasonable price point of $49.99. While the set improves in person compared to promotional images, the mismatched molded head and brick-built jaw hurt its overall appearance, especially for fans expecting greater accuracy to the show. Still, it introduces a new dragon mold and brings a notable character to LEGO form for the first time, making it a worthwhile—if imperfect—addition for Ninjago collectors.”
