Rediscover a fan-favorite gimmick with the Function X Series by FansProject, a celebrated line of 3rd party Transformers featuring fully transforming headmaster-style figures. Designed for collectors who love retro-inspired mechanics with modern articulation and stylized detail, this series delivers dynamic alt modes, classic character nods, and high-quality builds.

Each Function X figure transforms from a robot into a vehicle, beast, or cybernetic alt mode, with a removable head unit that becomes a pilot-style companion. These designs blend 1980s toy influence with FansProject’s signature aesthetic—angular, tech-heavy, and collector-focused.

Why collectors choose the Function X Series:

• Headmaster-Inspired Design – Removable head units transform into companion figures, paying homage to one of the most iconic G1 features.

• Stylized but Recognizable – Classic character archetypes reimagined with FansProject’s sleek sculpting, sharp lines, and updated proportions.

• Solid Engineering – Reliable transformations with strong joint tolerances, quality materials, and poseability built for display or handling.

• Unique Alt Modes – Includes everything from futuristic tanks and jets to cyber-animals—each packed with detail and personality.

The Function X Series offers a unique niche in the 3rd party Transformers world by delivering homage figures that don’t copy—they reinterpret. The result is a toyline that appeals to longtime fans of the originals while providing something fresh and modern for today’s collectors.
