|First appearance||"War is the H-Word"|
The Sphroids are pink semi-sentient ball-like creatures on the planet Spheron I. Their leaders are known as "Brain Balls". The Spheroids appear to attack by hitting and bouncing on their target. They lost their planet in a war against Earth and had to relocate.
The Spherons were likely a very resilient race, considering that their home world had no natural resources of which to speak.
