Michelle is the moll of the crimelord Victor Drath.
The Transformers cartoon
Michelle was present when Drath and Old Snake transferred Rodimus Prime, Springer, Ultra Magnus and Arcee into humanoid Synthoid bodies. She didn't seem to like this very much, and when the humanized Rodimus turned up on her doorstep, she helped him hide from Drath's men. The next morning over breakfast, she said she would help Rodimus get into Drath's house and help him get back into his original body, but instead she led him into a trap, allowing Drath to recapture him. She was later arrested along with Drath and his men.
