During the Great War
During a battle on Cybertron, Arcee requested rendezvous points from Team Delta, while bantering with Tailgate: he had failed to tag a sniper at an artillery depot, forcing her to break rank and engage the enemy hand-to-hand. Before she could regroup at his position, Arcee was captured by Airachnid and tortured for information. She proved too resilient, so Airachnid brought in the wounded Tailgate and killed him, despite her desperate pleas that she knew nothing about what the Decepticon wanted. As Airachnid was about to dispense with Arcee, Bumblebee and Cliffjumper burst in, forcing her to take flight. As the duo took away Arcee, she was in hysterics about her inability to save her partner. 
The team's fate is currently unknown.
