A father in Shaoxing, eastern China’s Zhejiang province, has manmade a gigantic transformer for his son, who is a fan of the heroic autobots.

The transformer is 4.2-meter tall and weighs 4 tons. What makes it even more unique is that it has room for people to sit inside and control its movements.

It took the father over a year and nearly $90,000 to complete. The doting father is hoping this colossal and unique present could ignite his son’s creativity.
