Second Sensorite

The Second Sensorite was one of two Sensorites that boarded Maitland's ship.

After some tense moments, the two Sensorites negotiated with the First Doctor that he, Susan, Ian, Carol and John would accompany one Sensorite to the Sense Sphere while the other Sensorite would remain on the ship with Maitland and Barbara. (TV: The Sensorites)
