Article Summary

Upgrade your Cosmic Legions collection with the new Experiment AA-20 Character Pack from Four Horsemen Studios
Includes two alternate head sculpts, helmeted and unmasked, plus two pairs of interchangeable hands
Accessories are paint-matched for Experiment AA-20 and compatible with most Mythic and Cosmic Legions figures
Pre-orders now live at $13.99, with shipping expected in Q3 2026 for new ways to customize your figures

Cosmic Legions takes place in the Cosmerrium galaxy, a vast setting with multiple factions, planets, and conflicts. The stories center on groups such as the Traders Union of the 5 Circles of Cosmerrium (T.U.5.C.C.), heroic adventurers, space zombies, and alien warriors. Figures are 6" scale, highly articulated, and often interchangeable with parts from other figures. Extra add-on packs are also released, featuring additional heads, weapons, hands, or armor, allowing collectors to customize or create entirely new characters. Four Horsemen Studios has now debuted some brand new Character Packs for their recent Cosmic wave, like the Soldiers of the T.U.5.C.C. Experiment AA-20 Upgrade.

These packs are designed to enhance your existing figures, instead of releasing a whole new figure. Specifically, this set includes two alternate head sculpts, an unmasked head and a helmeted head, as well as two pairs of interchangeable hands. All of which have been paint‑matched to work perfectly with the Experiment AA‑20 figure from the T.U.5.C.C. faction. However, Four Horsemen was sure that these head sculpts and accessories would also work perfectly with other releases, including the Mythic Legions line. Collectors can change up their collection in Q3 2026 for $13.99, and pre-orders are already live on BBTS.
