Hidden Spark on Earth (TFP)
82 parts Complete MatureA terrified girl finds herself mixed up with three other children in a war that had somehow reached to them. Unlike the other children, she did not have a home to go back to. Scars like hers run too deep and she does not know what worth she could even give to the transformers who have now become her guardians to protect her from decepticons.
Her near constant presence in their base seems to be a bother to the transformers, she can tell even if they do not say it out loud to her. The girl is not a fool. However, when they realize just how deep her pain truly was and how far she is willing to end it, Optimus is unwilling to give up on her. She does not understand his reasons, they slowly become clear.
And when she finally runs in with Optimus's arch enemy, she finds herself eyeing off a certain decepticon leader in a way that she should not have. And she did not know why. Megatron himself feels he simply had taken something so precious from Prime, and enjoys watching the autobot panic in trying to find her. But, the girl began to confuse his spark. So much so he questions so much about himself.
