The hero of the story, but hero may be a loose term to describe him. Cade was a Jedi Padawan who was separated from his fellow jedi and family when the Sith attacked the Jedi Temple on Ossus. After being rescued by a pirate crew, he became a pirate himself.Despite his obvious inheritance, Cade doesn't want to know anything about either Jedi or Sith; he just want to be left alone. But as he's about to discover, sometimes things aren't the way one wishes, and that we must take what is given.
Anti-Hero: Type V in the beginning, Type IV through the main series. By Legacy — War, he is a Type III.
Gun And Sword: His most used weapon is a lightsaber, but unlike the Jedi (or the Sith) he isn't above using blasters, sometimes at the same time.
Healing Hands: Force Resuscitation. To wit; it can heal normally fatal wounds, and also kill much more efficiently than any known weapon. Two big drawbacks; it's fueled by the dark side (the Jedi on Ossus were trying to figure out how to fix this), and the recipient must accept it, or at least not actively reject it, or it won't work. It was made compatible with the light side later, though.
The Hero: He's forced to take this role by virtue of his bloodline only. If he had his own way, he'd still be smuggling and racking up bounties in the Outer Rim with no worries.
Mage Killer: Hates Jedi after seeing one kill his father. Specializes in Yuuzhan Vong weaponry, over which the Force has no control. This caused some friction between him and Cade when he reveals he's a Jedi, but they got over it.
The trusty droid that has served the Skywalker line for generations, and is given to Cade partway through the series. Apparently he was owned by K'Kruhk in the meantime. He doesn't receive the usual attention he usually does though, but does get a few gags and plot-important moments.
Demoted to Extra: He's basically just here to show that Cade isn't entirely the last remnant of his line.
The main villain of the series, Darth Krayt is a powerful Sith Lord who abolished Bane's Rule of Two to instal the Rule of One. Unlike the other Sith Lords, rather than just gaining power for his own sake, Krayt seeks to bring order to the Galaxy, even if that means to commit genocide. Ruthless and unforgiving, Krayt rules the Galaxy with an iron fist. He used to be a Jedi named A'Sharad Hett, who upon seeing the Republic and the Jedi order fall under Palpatine, plus the Yuuzan Vong invasion, decided to turn to the Dark Side and create a powerful New Sith Order that would keep the galaxy safe and united.
Big Bad: Of the entire series until the end of War, save for the interim period while he's dead, during which time Wyyrlok handled the role.
Body Horror: His Vong infection threatens to do this to him.
Darth Vader Clone: Shares many traits with Vader, down to being a fallen Jedi, though with the twist that he's the Big Bad rather than The Dragon (and his Dragon, Wyyrlok, more strongly resembles Vader's master, Palpatine).
Really 700 Years Old: He was born in 47 BBY, and was friends with Anakin Skywalker when he was a young boy. He lived until 138 ABY, and fought Anakin's descendant far down the line, Cade. He accomplishes this by hibernating in order to prevent his Vong infection from killing him.
Sealed Evil in a Can: Due to his infection with Vong biots, he must hibernate to extend his life and prevent the infection from killing him.
The Emperor: He has the strength of personality, but his authority is pretty much limited to the select few who follow him out of genuine loyalty. He allowed the military and his moffs to take the controversy surrounding the Ossus Project and run with it to start a war that ended with the galaxy being handed back to the Sith on a platter, and his tenure as emperor on Coruscant lasts only a few days.
Evil Overlord: Subverted; he's a ruthless but fair ruler, by all accounts.
This is epitomized in one scene from War in which he subverts the dickery of previous Emperors by choosing not to use chemical weapons on the Sith homeworld. Why? Because he's better than that.
Then played straight in the last issue, when he goes full Fallen Hero, as he gets so desperate to win, he's willing to use the aforementioned chemical weapon on Coruscant.
Head-in-the-Sand Management: He really should have known better than to trust Veed and Calixte, or to ally with the Sith during the Sith-Imperial War.
It's All About Me: As long as he's Emperor when the Sith are finished, he doesn't really give a damn what he has to do to accomplish that goal.
The Hero: Ironically much more so than Cade, the actual protagonist. Antares is very much Lawful Good and wants to serve his emperor, protect Marasiah and stop the One Sith. Despite being sorely tested, he doesn't slide anywhere near as close to the Dark Side as Cade, nor does he allow Emperor Fel to do so.
Heroic BSOD: After revealing to the Sith vital information, under the false belief that they had Marshia Fel captured.
My Master, Right or Wrong: Whenether Roan Fel takes some morally questionable decisions, he's torn between loyaltly to him and to do what is right. When Fel, in order to extreminate the Sith, planned to use a lethal virus in order to wipe out all life on Coruscant (not knowing that it'll kill everything except the Sith), Antares fights and kills him.
Berserk Button: Never tell him about surrender. Unless it's the enemy's surrender.
Breakout Character: John Ostrander, the creator behind Stazi, only meant to include him on Trust Issues as a way to explain what had happened to the remnants of the Galactic Alliance. However, due to positive fan reaction and his own enjoyment in writing the character, Ostrander decided to expand the character further and create an arc that revolved around him.
Ascended to a Higher Plane of Existence: He's a force ghost. His time and nature of his death remained a mystery, but it's obvious that, after 130 years, even if he wasn't killed he would have died of old age.
