1. Hero wins. Just better.
2. Wrath. Easily comparable to Kenobi + Korriban.
3. Don't know enough about them.
4. Sion. The GI is no match for a true Sith Lord, especially on Malachor.
5. Sadow shits on him. Vader at that point struggled with random Jedi Masters.
6. Dooku will always dominate.
7. Scourge, he feeds off of Vrooks spite to reach unfathomable levels of power.
8. Horn force pwns him probably.
9. Jaina can replicate Revan's feat.
10. Probably Kun. Luke is always very hard to gauge.
