Adam was one of the young humans and aliens who became a follower of Dr. Sevrin who sought the mythical planet Eden in 2268. An accomplished musician, he played a guitar-type instrument, singing songs of Sevrin's call for an abandonment of technological society and an embrace of the natural life that preceded it. After stealing a shuttle from Starbase 4, Adam and the rest of Sevrin's group were apprehended by the Federation starship Enterprise. He aided Sevrin in disabling the ship's crew and appropriating Enterprise shuttlecraft Galileo II,. He died, along with Sevrin, when he ate an acid-saturated fruit on a world he thought was Eden.
