Presenting Arcee from the Transformers Prime animated series. Arcee is a Cybertronian Scout - when is she never a scout? One of
Optimus Prime's best actually.
Except this particular Arcee is suffering from a severe case of Survivor's Guilt. Before the Autobots in the Transformers Prime universe abandoned Cybetron in what would be later called the Great Exodus, Arcee was paired with an Autobot named Tailgate.

During a mission, Arcee was captured and tortured for information by the Decepticon Airachnid. When Arcee refused to reveal any information, Airachnid brought our Tailgate - who was apparently also captured. Tailgate was tortured will Arcee admitted that she did not have any valuable information. Satisfied, Airachnid killed Tailgate. Arcee was rescued before Airachnid could do her in as well.

After the Exodus, Arcee was again paired with another Autobot, Cliffjumper. He not only looks like Tailgate, he gets killed too - well later he gets re-animated as a psychotic Zombie, cut in half by Megatron and scattered in a mine. Anyway, this drives Arcee - understandably over the deep-end and Arcee ends up hating having to be paired with anyone. Ironically, she's assigned by
Optimus Prime to protect the human Jack Darby. You can imagine her joy at having to protect someone from the Decepticons.
