Darth Malak and Darth Bandon vs Darth Traya and Darth Sion

Battle takes place on Korriban

Which Master and Apprentice teams wins?

Traya and Sion, Bandon is a weak link in comparison to those two; and while Malak is above either of them on their own, he isn't strong enough to defeat them both by himself. Which is essentially what it'll boil down to, Malak vs the duo.

Team 2.
