Unidentified Chiropteran (Transformers)

The "Chiropterans" are an unnamed race of bat-like creatures from the planet Cybertron.

Biology
The Chiropterans are organic bat-like creatures that scale around the same size as Humans. Given by Nightscream's beast mode, these Chiropterans had grey-furred skin and a long, pointy nose. They could also apparently emit a sonic echo.

History
The Chiropterans lived on Cybertron roughly many centuries ago, their existence predating the Cybertronians. However, they later went extinct due to unknown causes.
