Transformers: Prime (2010)

S2E7 Crossfire

Megatron dispatches Dreadwing, Airachnid, and Breakdown to trace a possible Energon source, unaware that Dreadwing and Breakdown have been secretly instructed to eliminate Airachnid for her betrayal. Sensing danger, Airachnid confronts Breakdown, ultimately killing him and fleeing into the forest. She discovers an abandoned Energon mine where she finds Starscream in a panic, cornered by a formidable Insecticon. Utilizing her powers to dominate the creature, Airachnid contacts Megatron, luring him to the mine with the intent of using the Insecticon to eliminate him and seize control of the Decepticons for herself.
