"What they hey is a Tri-Droid?"
That is a question most often uttered around this...thing. It's a three legged robot alligned with the Seperatist movement during the Clone Wars, 20 years before some farmboy blew up the Death Star while harboring secret fantasies about his own sister.
The Tri-Droid most overwhelming talent is its ability to push members of online Star Wars forums, or "dorkboards", to jam through long group conversations about everything BUT the Tri-Droid. It's a beautiful thing, and it brings people together.
