MALE DOMINANCE!!!
~~~~~Naga Sadow's Assessment~~~~~
Raw Power: This is a bit tricky to gage. In my estimation, he is the second most powerful of the Ancient Sith – behind Marka Ragnos. The Ancient Sith used amulets, Sith Swords, and other items to increase their power – as well as doing Sith experiments on themselves to alter their physical and Force strength. So, that makes it difficult. However, On Ziost at a council of the Sith Lords, (they are voting on a new Dark Lord of the Sith), one Sith Lord pronounces: “The strongest of the Sith Lords. The bloodline is strong in Naga Sadow.” Quite the ringing endorsement, and about the best power estimate we can get on that front.
Force Mastery: Naga Sadow certainly excels in this department, although again – we don't get to see a whole lot of it directly. He was an extraordinarily gifted Sith Sorcerer. He was able to use Sith alchemy and sorcery to alter numerous races and bend them to his will, even creating the Sith wyrm through his experiments. His knowledge was great enough to turn Freedon Nadd into a powerful Sith Lord; allow Aleema and Satal Keto to found the powerful Krath secret society using Sadow's Sith Sorcery teachings; and turn Exar Kun from an Anakin Skywalker-like saber master into a powerful Dark Lord of the Sith with incredible knowledge and mastery of Sith alchemy and sorcery. Naga Sadow's ship – powered by a Sith crystal probably designed by Sadow himself – was powerful enough to use the Force to rip the cores from stars.
Naga comments on the Old Republic's blaster technology: his thoughts? “Not very impressive.” Implying the Sith had access to more advanced stuff. Or at least, Sadow himself did. During their battle, he doesn't throw a brick at Ludo Kressh, he rips three out of the tomb wall to slam into Ludo. That takes a lot of precision and control. Clearly, he doesn't want to damage or destroy the temples. He is capable of using Force Drain. His amulets – we all know – are incredibly powerful. They amplify the wielder's rage a hundred thousand fold (no, I didn't make a mistake there), and “with every pulse of anger, the amulet doubles the power of its discharge.” Capable of vaporizing several Massassi warriors at once and destroying stone walls easily, as well as blowing massive holes through the Sith wyrm. He's a master of Sith illusions, and might have actually taken Coruscant had Gav Daragon not betrayed him. Over the skies of the capital city, one spectator cries out, “It's an incredible fleet! Tens of thousands of ships!” Naga himself says that:
“Here in my meditation chamber I can see the galaxy in my mind's eye. I can visualize vast armies, powerful fleets, invincible warriors. And with my Sith arts, my imagination can make them real!”
Combat Ability: Here's where it gets really tricky. We only actually see him fight one opponent ever. Sadow's Sith Sword glowed when he struck it to the ground. He says, “I call upon the power of the Sith, the power of my Jedi blood, the power of the Dark Side!” It answered the call. For those of you not very familiar with Sith Swords:
”The alterations [of the Sith Sword] allow the blade to deflect blaster bolts and lightsabers, just as lightsabers themselves do. The blade also focuses the Force energy of the user, giving an unnatural sharpness. As the wielder grows more proficient in the power of the Dark Side, the blade becomes more deadly...Sith Swords are effective against lightsabers because of the way their alchemically altered metal refracts the lightsaber's energy.”
They do weigh much more than your typical lightsaber, though (2 kg for a saber, 6.5 kg for a Sith Sword), which would make them slower. This taken into account, his Sith Sword is seen as four blades at one point, while Ludo's is depicted as two, indicating that Naga Sadow was pretty fast. Before the battle ends, Ludo is the one bleeding and Naga has his sword extended directly out, while Ludo's is down and looking worried. Then, Ragnos interrupts. Added to his saber abilities are his tremendously overpowered amulets, his talisman, and lightsaber resistant armor which also increases his physical strength. It is safe to say that his combat abilities are certainly dangerous to just about anyone in the mythos.
Conclusion: Here's where it gets fun. I think Naga is definitely top tier. Not on his own, no. But with all of his equipment and whatnot? Definitely. And its wrong to hold it against him for using his equipment. It'd be like Batman without his belt, or Ironman without the suit. Naga, presumably, made all of his equipment. He even gives a Sith amulet to Gav Daragon, who was essentially expendable. If he hadn't made them himself, I don't see why he would be so generous with them. The Sith Council calls him 'the strongest of the Sith Lords' and acknowledges the power in his bloodline. Ludo fears him and his proficiency with Sith alchemy, saying so at several points:
“Your rebellious actions and experiments are a threat to us all.”
“Stepping in dangerous waters, unleashing powers you do not understand.”
Sadow, personality-wise, seems like the Sith we're used to seeing. Arrogant, devious, powerful, brilliant. He's clever enough to stage an attack on Ziost and frame the Old Republic for it, getting himself declared Dark Lord of the Sith in the process. He lures Ludo, his archrival, into attacking a useless base and then counterattacks with his own massive fleet. He uses his Massassi warriors to slay numerous Sith Lords, and personally kills Lord Simus – the wisest Sith Lord and personal teacher and mentor of Naga. Then he summons up the largest fleet the Sith empire had even assembled, faster than 'any force in the history of the galaxy.' His attacks on the New Republic would have been successful, despite being vastly outnumbered – if his meditation sphere hadn't been struck by laser-fire from Gav and disabled. Nonetheless he manages to escape, destroying large numbers of Empress Teta's fleet as well as Ludo Kressh's, before staging his death and living out the rest of his days on Yavin.
He seems to not be nearly as frightened of Marka Ragnos as other Sith Lords are (which either indicates a higher level of common sense or a higher level of power). When confronted by Ragnos himself on Korriban (as a ghost), he's actually blatantly rude:
“What is so important that you could not leave us in peace to resolve our own differences?”
After Ragnos commands Ludo Kressh and Naga Sadow to make peace (an offer which Ludo is eager to do), Naga rejects this notion outright: “It requires more than the pronouncement of a ghost for me to forget my sworn enemy, Ludo Kressh.” So, yes, Sadow is definitely a badass. Plus, he is definitely the coolest looking Ancient Sith (and he's bald!). Combine this with his powerful amulets, strong Sith Sword, stronger magic, and impressive knowledge of “ancient” (even by the Ancient's standards) Sith knowledge – I would say that Naga Sadow is definitely a top tier combatant and Force user, capable of beating nearly anyone if he were to fight smart...which is a given, seeing how cerebral he is.
