Aboras is one of two ancient Kaiju that were released in episode 19 of Ultraman. A monster whose rivalry with the fellow ancient monster Banila has persisted for centuries, the original Aboras was sealed away by humans in the distant past, but was released after scientists found and inadvertently activated the capsule he had been contained in. The stronger of the two monsters, Aboras managed to defeat Banila, but then turned his ire on the SSSP, forcing Ultraman to take action.

Aboras is one of two ancient devil beasts sealed away eons ago and the archenemy of Banila. The destructive twin behemoths remained trapped within their capsules, until the container for both capsules was unearthed, Banila's having fallen out. While Aboras’s capsule was taken by the Science Patrol, Banila’s capsule accidentally got transported to the dump, where the dirt from the excavation was taken. Aboras's capsule was tested on by scientists, but once it surged with electricity, the capsule was opened, releasing Aboras. Aboras breathed out the light blue mist at the buildings, then the buildings covered with the mist foamed up into a sticky goo and corroded.
