A huge cosmic cloud is reported moving into the outer fringe of the galaxy. Starfleet Command sends the Enterprise to investigate. Sensors indicate it is a strange combination of Matter & Energy. It seems to engulf and feed on the energy of planets. It makes a deliberate course change to head towards the populated planet of Mantilles indicating that it could be intelligent. Kirk sees it as a threat to every planet in the galaxy and if they can't communicate with it and make it stop it will have to be destroyed. Written by

Captain, I have completed the analysis of the target area. Unfortunately, the brain is so vast, our entire offensive armament will not assure its destruction. However, the brain could e completely destroyed if we convert the entire ship to energy aimed at the brain's cortex and expand the energy in one mortal strike.
That sounds like you're telling us to blow up the ship.
I believe that is what I just said, doctor.
