Fierce Blade Lion (Qiji 3601)

About this set

The Blazing Blade Lion is a mech set from KEEPPLEY's Nucleus Crystal Boy line, set number 3601, with 246 parts on the box and a 6+ age mark. Difficulty is rated 2/5, so it sits firmly in beginner territory. The finished model is a lion-shaped mech in red, orange, gold and black, with gold parts concentrated on the head and outer limbs over a black frame, giving it clean visual layering. It uses joint structures, so the limbs can be posed, and it comes with weapon accessories. The main draw is the official Nucleus Crystal Boy license and the 2-form transformation, which is the part worth trying first once the build is done. Build the black frame before adding armor panels, and watch pin orientation at the joints, since fixing a reversed pin later is annoying. At 246 parts it is a roughly one-hour build, a good fit for kids aged 6 and up new to mech sets, and for collectors who want a small lion mech for the shelf.
