Transformers: Prime - Season 2 - Eps 7: Crossfire
Megatron sends Dreadwing, Airachnid and Breakdown to investigate the trail of a potential Energon source, but what Airachnid doesn't know is that Dreadwing and Breakdown have actually been ordered to kill her for her treachery. She eventually catches wind of this, however, killing Breakdown and running off into the woods. Upon arriving at an abandoned Energon mine, Airachnid encounters Starscream cowering from a large Insecticon. After using her abilities to control the creature, she contacts Megatron and tells him to come to the mine, planning to use the Insecticon to kill him so she can claim Decepticon leadership...
