Martian Shape Shifters

The Martians has a number of giant robots.

They could take a medication that would allow them to shape shift into any body configuration they wanted.

They could become living radios, or even tiny helicopters.

They found it helpful, but the drawback was once they achieved a new shape they had to retain it for a long period of time, perhaps months, so choose wisely!

This one had an extra strong skin so it would not be burned by the acid fuels they used.
