Vergere. Or, as we like to call her, Torture Chicken.
She originally started out as a Jedi that ended up with the Vong and picked up...a fair bit of their ideology. Tortured Jacen Solo to basically mentally break him in an effort to convey her ideology. Some people
really really really like that ideology, the character, and the book it's in (
Traitor, in the NJO series). Stover is one of our favorite EU authors, but to be brutally honest, we always found Vergere to be incredibly preachy and toeing the line of 'cringe Grey Jedi' stuff.
Her ideology is supposed to be above the petty Jedi and Sith ones, but it just comes off to us as, again, incredibly preachy. We're not going to say the Jedi are 100% right (the Sith sure as hell aren't) but Vergere is...yeah. 'There is no Dark Side' 'The Force is the Force' comes very close to some of the worst bits of the EU.
(her being retconned into a Secret Sith planting the seeds that would later turn Jacen into Caedus is...well, if you're going to be making Jacen Solo into Bargain Bin Anakin Skywalker, that's the way to do it.
Lots of people hated it, though, because lots of people liked her ideology.)
The Ganner was great, though
