Metamorpha

Metamorpha was a Class M planet in Galaxy Telpha 7. It is the home to a sentient humanoid species, the Metamorphans.

Hundreds of years prior to the 2260s, an asteroid collided with the planet, and brought about rapid chemical changes. As a result, the planet entered a state of rapid changes and upheavals on the surface, and the populace was converted to energy.

This state of affairs continued until the 2260s, when the USS Enterprise (NCC-1701) visited the planet, searching for the planet's natural Tiantianium deposits.
