Derpy Tiger’s LEGO personality starts with a very carefully designed face
A desk review of KPop Demon Hunters set 72537, where shaped bricks, printed eyes and adjustable poses work together.
Character first, piece count second
Some character models need a label before the subject becomes clear. Derpy Tiger and Sussie Bird 72537 takes on a more expressive challenge: capturing a personality through the face. This desk review examines LEGO’s published design story and product information, without claiming a hands-on build.
Announced in June and released on August 1, 2026, the 825-piece KPop Demon Hunters set brings the two characters into a display that also invites posing. The most interesting question is how physical parts and graphics cooperate to make that display feel animated.
The eyes are a collaboration
LEGO’s account identifies Senior Design Master Wes Talbott and graphic designer Conrad Hallenburg Sode Rasmussen among the people behind the model. It describes a process that combined the shape of the brick-built face with printed features, paying particular attention to the angle and almond shape of the eyes.
That relationship is worth studying in the official photographs. The physical structure establishes a head and muzzle; the graphics give those surfaces a very specific expression. Our interpretation is that either layer would be less convincing alone. Building a recognizable character requires judging the face as a whole, rather than treating decoration as a final afterthought.
A shelf display that can change its mood
The product description lists two facial expressions, movable parts on Derpy and a rotating neck and posable feet for Sussie. The accessories include two love notes and a flowerpot, with a storage compartment in Derpy’s head. With the bird on top, the model measures approximately 21 cm high.
Those options suggest a pleasing way to live with the finished build: choose a pose with a small narrative. A note can turn a static arrangement into a delivery; a change of head position can make the bird seem to notice something beyond the display. These are suggested arrangements, not observations from our own testing.
What to look for before deciding
Compare the official front and angled photographs at the size you expect to see the model on your shelf. Consider whether the expression still reads from across the room, and whether you want space to reposition the accessories.
For custom character builders, the useful exercise is to start with one expression and make several small variations in eye angle or mouth shape. Photograph each from the same position. A tiny adjustment may change the personality more than adding another layer of detail. Derpy provides a lively subject for thinking about that relationship between geometry, graphics and character.
