Aquaman battles a creature that at the end of the issue explodes in outer space. A few years later, the very same creature emerges in the Marvel Universe from an explosion in outer space. This has to be one of the most underrated and coolest hidden gems in Comics History. – Odinson, Lone Star Comics Archivist
