The Probe Bat heavily resembles the Gryphon, but also resemble bats. The Probe Bats are very big, having twelve-foot wingspans.
In lake Apopka, the bio-metallic meteor begins to stir like a mass of liquid metal, enters a cave and absorbs a whole colony of bats creating the Probe Bats. In Kentucky, the Probe Bats continued to absorb animals after Godzilla appeared in San Francisco, returning to the cave with their genetic collections to deliver to the main mass of the probe, the Gryphon, which is slowly starting to take on a definitive form. Vaught, upon hearing Kenoshita's story, concludes that Godzilla was headed for Kentucky, where the meteor crashed. When Vought finds a tunnel leading to the a series of caves and gets to the probe, it had already become the Gryphon.
The Probe Bats can fly.
The Probe Bats can absorb the genetic material of Earth's animals.
