A plot where Torchwick fakes his allegiance to a greater evil in order to protect Ruby could be really engaging. He has to keep up the act while secretly helping Ruby and her team.

Their relationship would be full of mistrust, but also moments of understanding as they both fight against a common enemy.
One plot idea could be Ruby trying to redeem Torchwick. Since he's a villain in the original series, Ruby could see some good in him and attempt to turn him to the side of good.
