Darth Plagueis and TPM Sidious vs. Tenebrous-possessed TPM Anakin

1. Force
2. Sabers
3. All-Out

I read a really interesting fanfiction that tackled the concept of Vader being transported back to his TPM body a while back. He was much weaker because the body he was in was less used to using the Force and had less midichlorians overall due to his smaller overall number of overall cells. It was a great time travel fic. Wish I could find it again.
