Key Features

• Movie-inspired 2-in-1: The design reflects the Transformers One origin story and provides both robot and Cybertronian truck modes for cinematic play.

• Compact 4-in size: At about 4 in (10 cm) tall in robot mode, it is easy to handle, store, and combine with other figures for staged battles.
• Cog lockout feature: The built-in lockout limits conversion until unlocked, which helps avoid accidental transforms during rough play or transport.
• Durable play focus: The simple mechanism and solid construction prioritize repeated interactive play rather than delicate display detail.
