In my opinion, Kabal, but storywise, Mavado is probably more important.

i like kabal, but i admit that mavado is a pretty sick character, story and style. mavado should have better special moves and a better fatality, but kabal should just be revamped (look and story-wise) and his specials should be enhanced. but overall i choose kabal because he was my best character in mk3.

Look i'd go with Mavado,he just looks like a bad ass.But playablity hands down Kabal,he has better moves and combos.And the fact that Mavado used rubber bands to fight hurt him in my eyes.But both have alot of promise and i would like to see them both return to finish thier feud.

Mavado is the best
