Tangible God
Lets all love Lain
To be a Villain or Hero, you would have to be on the level of Famous.
Well, despite everyone else, chances would have it that the Villains would win. They have the God-like Ragnos, Sadow, Kressh, and the other famous Ancient Sith.
Then you have Freedon Nadd, Exar Kun, Ulic Qel-Droma, Revan and Malak, Kreia, Sion, Nihilus, Bane, Kaan, Plagueis, Palpatine (at his zenith as Dark Empire Palpatine) Vader, Dooku, Maul, and any other Sith that is of Famous Villain status.
Not to mention all those famous NON-Sith. I guess you've got Saul Karath, Tarkin, Jango and Boba, Piett and Motti (possibly Famous villains) Pelleaon, Thrawn of course, Warlord Zsinj. Then I guess you have to add the famous Yuuzhan Vong whom I'm not naming.
They may not all have superior weapons, but they're Villains. Stack them up against:
Luke(NJO God?) Han, Chewbacca, Leia, Lando, Ackbar, Yoda, Obi-Wan, Anakin Skywalker, (good one) Mace Windu, Ki-Adi, Aayla Secura, (sighs) I sadly assume that Kit Fisto and Plo Koon COULD be heroes. Jaina, Jacen and Anakin Solo, Bastila, Carth, Canderous, Lord Hoth, perhaps Vrook and Vandar, etc. etc...
Unfortunately Ragnos and his Ancients alone would likely decimate anyone, even without lightsabers, maybe with the exception of NJO Luke. I know you said no God Powers, but you can't mention alot of the EU Villains without their Godly abilites, that's who they were.
All in all, the Heroes are heading for an early grave, despite Han's lucky shot.
