Cosmic Legions: Mortal Thorn ACU-3 Action Figure (Preorder)
Four Horsemen Studios' Cosmic Legions line has earned a devoted 1:12 scale collector following for its extraordinary world-building and interchangeable part systems, and the Mortal Thorn ACU-3 is one of its most ambitious entries yet. Representing the cutting-edge third generation of Autonomous Construct Units from the lore of Cosmerrium, this figure captures the tension between technological marvel and corporate intrigue — a must-have for sci-fi collectors invested in the Cosmic Legions universe.
This figure arrives factory sealed in its original packaging. The fully articulated PVC construct stands 6 inches tall and showcases Four Horsemen's signature weathered metallic paint work, blending gunmetal silver with aged bronze accents across the armor plating. The set includes a standard antenna head and a striking alternate skull-faced head with blue glowing eye details, a swappable eye attachment, a grenade launcher, a pair of antennas, and three swappable armor pairs covering the shoulders, thighs, and shins — allowing for meaningful display variation right out of the box. The interchangeable armor system is the hallmark of the Cosmic Legions line, letting collectors mix parts across figures in the wave.

Jays is my first stop in collecting. I preorder things through Walmart, Amazon, Hasbro Pulse, etc., but Jays always seem to get the items and either meet or beat the other companies pricing. I always end up cancelling my pre-orders and going with Jays. Better selection, price and MUCH MUCH better shipping quality. You can't even compare anyone else's shipping and packing to Jays. And that's why Jay's blows them all out of the water.
Great fast shipping, packaging with care. I am definitely buying from Jay's again! Such peace of mind knowing my items will arrive minty. 5 stars!
Perfect and careful packaging, shipped super quick. Thank you, will definitely be following the store!
Didn't pull any punches in item description. Came extremely fast and well packed. Extremely happy being a first time buyer! Thank you.
I've been buying from Jay's for a while now and I am never disappointed with the experience. Prices that can't be beat, easy PayPal option, and lots of bubble wrap surrounding the products. The fact that they go out of their way to make consumers happy keeps me coming back.
This is my 3rd or 4th time I have ordered from Jay's. The orders are always correct and arrive pretty quick and packaged extremely well. Best in the industry.
