The Giant Bat Creature

The Giant Bat Creature  is the titular character and an antagonist in the sci-fi monster film Terror from Beneath the Earth. It has since become an iconic Mihmiverse monster.

Terror from Beneath the Earth
After years of atomic weapons tests deep within the Wisawa cave system, residual radiation has altered the fauna in terrifying ways - including creating a man-sized, grossly mutated, bat-like creature with unusual powers!

This giant bat monster has a distinct taste for human flesh and posseses the ability to paralyze its prey using an internally generated electric field!

The Giant Bat Creature kidnaps Danny Johnson and Alice Johnson. Dr. Edwards and Rosemary Bennett go to the Phantom Lake Police Department after finding Alice Johnson's notebook. After reporting the find to the local sheriff, Dr. Edwards and Rosemary are tapped to lead a rescue attempt. Along with the sheriff and small-town farmer Stan Johnson, the rescue party quickly comes to the realization that if the caves don't get them, the Giant Bat Creature just might!

Dr. Edwards calls upon his colleague, Professor Jackson, to create a sonic device that will be a weapon against the Creature. However Professor Jackson had urgent business elsewhere and sent his pregnant wife, Julie Ann Saint Marie-Jackson with the device.

However, Dr. Edwards refuses to use the sonic device to kill The Creature, as he has moral objections to killing what is, as far as he knows, an animal just trying to survive, even if it was trying to eat women and children. Stan Johnson amplifies the sonic device to kill the creature.

The movie ends with "The End?" as the Bat Creature twitches a bit, suggesting it is not quite dead.

Destination: Outer Space
The Giant Bat Creature appears in a tavern/cantina on a distant planet.
