Comparing Two Obscure Collectible Figures That Keep Coming Up
People ask about Pseudoscorpiones Rex versus Scorpius Rex constantly on collector forums, mostly because they look similar at first glance and both carry a scorpion theme. The confusion makes sense. Both are aftermarket or bootleg toy figures that borrow heavily from Jurassic World design language, but they come from completely different manufacturers, target different audiences, and have very different build quality. I've handled both extensively, and I'll walk through what separates them beyond the marketing photos. The most persistent myth I see is that these are official Jurassic World licensed products. They're not. Both are unauthorized third-party figures, usually sold on marketplaces like AliExpress, eBay, or niche toy sites. Scorpius Rex is the more established of the two, having appeared in various Jurassic World toy lines from Mattel around 2018-2022 as an official figure. The Pseudoscorpiones Rex version is almost certainly a bootleg knockoff that reuses molds or creates its own inferior version. This distinction matters because it affects everything from plastic quality to paint application to resale value. Here's what you actually need to know before buying either one. The Scorpius Rex figure, even in its bootleg iterations, typically stands about 6 to 8 inches tall with a articulated tail that can curl upward into a striking pose. The sculpt tends to follow the film design closely: ridged back plates, a bulky body, and those signature scorpion-like tail segments. Paint application on decent versions covers most of the surface area, though joint areas often show bare plastic. The cheaper versions skip paint entirely and sell as unpainted gray or black resin-style figures.
The Pseudoscorpiones Rex is a different creature altogether, and not just because of the name. This figure appears to be modeled after an actual pseudoscorpion rather than a dinosaur, which explains the much smaller size and different body proportions. These figures are typically under 4 inches tall with eight visible legs, pincer-like pedipalps, and a tail that lacks the segmented stinger of a real scorpion or the Scorpius Rex toy. The sculpt quality varies wildly between manufacturers because there's no single standard mold. Some are crude and misshapen. Others are surprisingly detailed for the price point. I ran into a specific problem last year when a buyer sent me both figures side by side for identification. The photo made them look nearly identical at thumbnail size. Under magnification, the differences became obvious: the Scorpius Rex had joint articulation points molded into the legs and tail segments, while the Pseudoscorpiones Rex was entirely static with no moving parts. More importantly, the material was different. The Scorpius Rex used flexible TPE rubber for the tail, which allowed posing but degraded over time and became sticky. The Pseudoscorpiones Rex used rigid PVC, which doesn't sag but snaps if you force the legs into position. I learned to ask buyers specifically about material flexibility before recommending either one, because the maintenance requirements are completely opposite. The Scorpius Rex needs occasional powdering to prevent tackiness. The Pseudoscorpiones Rex needs gentle handling to avoid breakage. The pricing tells a story by itself. Genuine Mattel Scorpius Rex figures in sealed packaging run anywhere from $15 to $40 depending on the release wave and condition. Unsealed copies in decent shape go for $8 to $20 on secondary markets. The Pseudoscorpiones Rex figures typically sell for $3 to $12, mostly because they're novelty items without brand recognition. If someone is charging premium prices for a Pseudoscorpiones Rex claiming it's rare or limited edition, they're inflating the value. These are mass-produced from China with no scarcity.
Another thing people get wrong is the biological accuracy angle. Neither figure is scientifically accurate, but for different reasons. The Scorpius Rex is a fictional dinosaur created for the Jurassic World franchise, so it was never meant to be paleontologically correct. It's a genetic hybrid monster with a scorpion tail appended to a theropod body. The Pseudoscorpiones Rex claims to represent real pseudoscorpions, which are tiny arachnids no larger than a grain of rice in most species. A 4-inch toy version is already massively scaled up, but at least the body plan resembles the real animal: elongated cephalothorax, folded pedipalps, and a non-segmented abdomen. If you want actual scientific accuracy, neither figure delivers, but the Pseudoscorpiones Rex gets closer to representing a real organism's anatomy than the purely fictional Scorpius Rex. The display and storage considerations matter more than most buyers realize. I keep both types in separate containers because the Scorpius Rex's TPE tail off-gasses and can transfer residue to other figures stored nearby. I use acid-free tissue paper between joints and store them at room temperature away from direct sunlight. UV exposure makes the painted colors fade noticeably on both figures within a year, but the Scorpius Rex's vibrant green and yellow markings degrade faster than the more muted tones on the Pseudoscorpiones Rex. I recommend using UV-protective display cases if you plan to keep these out long-term, otherwise expect noticeable color shift within 12 to 18 months of shelf display. For anyone deciding between the two, the answer depends entirely on what you're looking for. If you want a posable dinosaur figure with articulation and a connection to an existing franchise, go with a legitimate Scorpius Rex from an authorized retailer. If you want a small decorative arachnid figure at a low price point, the Pseudoscorpiones Rex serves that purpose adequately despite its limitations. Don't buy either one expecting museum-quality craftsmanship. They're both budget-tier collectibles. The Scorpius Rex has the advantage of official design reference material. The Pseudoscorpiones Rex has the advantage of being a genuinely unusual subject for toy collectors who specialize in non-dinosaur creatures.
