Moonlight is Libbys adopted daughter that she found in Transformers: DOTM after they all defeated Sentinel Prime. She found her close to one of the broken cars with her parents missing so she believed that they passed away.

She only exists in the movies from DOTM onwards. She grows older and starts to take up after Libby and even become part cybernetic. She is still growing old and has a very close bound with her mother Libby.
