At a recent Nokia event in Hong Kong, Optimus Prime and Starscream showed up to impress telecommunication aficionados with their ability to become Power-Wheels-sized conveyances. Watch as these Transformers become robots only somewhat in disguise.

Starscream had a little trouble, which suggests that the Energon's got him leaning. And here are some more real-life Transformers (of various robotic and non-robotic vintages):

- A Transformer on American Idol.
- A transforming beer can.
- A transforming Swiss parking lot.
- A Taiwanese robot that can turn its wheels into legs.
