Darth Bane vs Darth Malak

Bane.

Bane, of course.

Bane wins.

Bane every time in a difficult fight.

Bane destroys. Hasn't changed.

In fact, Bane can probably kill both Darth Malak and Darth Revan at the same time, albeit high diff.

With orbalisks, Bane 9/10. He is much too durable, and more powerful with orbalisk armor.

Without orbalisks, probably bane 6-7/10. Malaks a better dualist and his power is comparable, but bane is more skilled and knowledgeable with the force.

Bane dominates.

Malak>Exar Kun>Bane
