SW Characters That Have Potential

If Disney were to bring back some SW characters, which ones would be full of potential.

Name who they are and what Disney could do to make them great again!

I’d rather they make new interesting characters rather than recycle old ones.

Exar Kun, Ulic Qel-Droma, Naga Sadow, Revan, Nihilus, Freedon Nadd, Kyp Durron

Tulak Hord would be a fine choice.

Lots to work with, especially in Lightsaber skills.
