Hepton was the Director of Operations for the Lorannan-Ycole Corporation.
He sent Thom Kelligan to make contact with the entity in Jupiter's atmosphere. After Kelligan was killed, Hepton decided the entity posed a danger to the Corporation and tried to destroy it. Now self-aware and a gestalt after having absorbed Kelligan, it fought to preserve itself. Norma Kelligan sacrificed herself to join with the entity and her husband's consciousness. The strengthened gestalt telepathically killed Hepton. (PROSE: Jupiter)
