Are you ready to face the ultimate challenge? Meet XT4, the tough and sassy robot that will put your hero skills to the test! This gadget-wielding cyborg has escaped from the Hero Factory and is now wreaking havoc on his home planet of Mechna. With razor disc slicers, striking blades, and a laser slicer, he's a force to be reckoned with. Can you defeat this heavy-metal machine and save the day? Don't forget to team up with hero 6221 NEX, or even combine with him for an even bigger model. But beware - XT4 is highly flexible and poseable, making him a formidable opponent. Think you're up for the challenge?
