A mercenary with no loyalty to any particular cause, Captain Shiner established himself as an enemy to the ThunderCats due to his repeated hire by Mumm-Ra. Shiner is a sophisticated and intelligent opponent, disdainful of the crude methodology of some of Mumm-Ra's other underlings such as the Mutants. In spite of his allying himself with Mumm-Ra, Shiner is not entirely without principles, and, perhaps surprisingly, seems to command a great deal of respect from the crew of his ship, the Vertis.
