Sora Bulq vs. Mace Windu vs. Depa Billaba vs. Echuu-Shen Jon

The four Vapaad practicioners decide to face off against each other! Who would win in this battle of the dark form?

The one who didn't turn to the Dark Side because of it.

Well, while Echuu did somewhat turned to the dark when fighting Sev'rance Tann, he went back to the light and started to meditate. But if there is no ganging up, then it's Mace Windu.

Even if they gang up, we've can expect Windu to shrug off most attacks, however that could be too much.

Depa > Sora
Mace > Depa
Mace > Sora
Mace > Echuu
Echuu ? Sora
Echuu ? Depa

Judging by how Shen Jon does, we can find the winners.
