Luminos (7506) is one of two non-human Super Joe adventure Team members and is part of the Night Fighters. He is essentially the same body mold as The Shield, except he is molded in all clear plastic and lacks a shield. His unique action feature is a small light in his head that will illuminate his interior sculpted face in a very cool way. The light can also be tilted down to illuminate his clear body cavity. Both of his arms and legs are articulated with clear rubber joints that deteriorated over time and therefore Luminos figures are always found in pieces as well.
Here are the original US Patent drawings for the Luminos figure.
