Porter was known to be calm and well-balanced.
In 2267, Porter was part of a landing party to Diad II that included Kirk, Spock and three other security officers. Their task was to round up crew who had failed to return from shore leave. They split up, with Porter and a lieutenant accompanying Spock. As they walked around a lake, Porter suddenly hallucinated something above them and ran fast into the savanna and waving his phaser in the air, retreating until he could no longer be heard. Overflow from the fantasy group mind of native butterflies was affecting the crew, making their own thoughts come to life. (TOS - The New Voyages short story: "The Winged Dreamers")
