Transforming Robot Building Blocks & Mecha Kits
Power Blockz transforming robot building blocks turn one model into two: build a truck, a car or a jet, then convert it into a standing mecha without taking it apart. The collection holds around 30 transforming block robots and mecha building kits, mostly Power Blockz exclusives produced with Sembo, alongside designs from Jiestar, TL, Tuomu and Seed. These are original designs, not licensed characters.
Car-to-robot building sets and mecha warriors
For a classic car-to-robot building set, try the Transforming Super Commander Car Robot or the Mecha Car Transformation City Robot Warrior. Truck fans can build the Convertible Semi-Truck Commander Robot or the Mechanical Transformation Truck Car Robot. Other conversions include the Transformation Flying Birds Robot Sky Knight, the Convertible Wasp Scout Robot from Tuomu and the Mecha Deformation Dinosaur Transformation. For armored warriors, look at the Bull Demon Mecha Warrior or the Endless Dawn Calamity Knight Mecha Rider from Jiestar.

Do these robot kits really transform without taking them apart?
Do these robot kits really transform without taking them apart?
Kits with “transforming” or “convertible” in the name, such as the Convertible Semi-Truck Commander Robot or the Transforming Super Commander Car Robot, are designed to switch between vehicle and robot using hinges and joints. Others, like the Bull Demon Mecha Warrior, are posable mecha figures rather than converting builds.
Are these official licensed robot characters?
Are these official licensed robot characters?
No. These are original mecha designs from Power Blockz, Sembo, Jiestar, TL, Tuomu and Seed, inspired by the wider robot and mecha genre. None of them is an officially licensed character. Titles describe the vehicle mode and style of each robot. They are sold as building and display kits for adult builders.
