Shrike-bat

Shrikebats are large, purple, flying, vaguely reptilian creatures. Found on Dromedon and Dread, a group of them is referred to as a "wreck" of shrikebats, or, more commonly "aiiiiiieee get them off get them off my eyes oh dear gooaaaarrrrrghkklgkglllll".

They're extremely vicious creatures. Thankfully, they don't like it when you invert polarities, which drives them off.

The Transformers cartoon
Kup had an encounter with shrikebats on the planet Dread. While narrating his time as a prisoner of the Orbs, he told tale of a wreck of shrikebats attacking his fellow prisoners.
