Airachnid (Transformers One)

Airachnid is Sentinel Prime's surveillance officer and primary enforcer. To call her "no nonsense" would be an understatement; the only time she smiles is when she's causing suffering or going in for the kill. She is an unrelenting and humorless hunter and spy with a vast array of receptors and scanners at her disposal, which allow for her to keep tabs on anything -- and anyone -- that might jeopardize Sentinel's claim to power.
