Lego Transformer

Here is Jonathan's Lego Transformer, called "Rockalot".

Here is his origin story;

Once there was a professor that had just invented a gun, and he wanted to try it out on something, so he shot a plane that was flying overhead. The gun turned the plane into this transformer. He is a good transformer.

Here he is as a robot.
 

This is his alternate mode, a giant rocket.

And here he is in his other alternate mode, a hover car!
