What makes a character the worst? It could be that they did something horrible, maybe their only reason for being there was to drive the plot in an aggressively annoying way, or they simply have no appeal — truly, there are tons of possibilities.
When it comes to science-fiction, it could be any of those, and more. The worst characters in sci-fi can be anyone, really, but there are definitely some names that come to most people's minds right away... *cough* Jar Jar *cough*
Regardless, most of the characters the fans either don't like or love to hate are often considered to be the worst for their onscreen behavior, or for whatever they did in their given story. Maybe they let all the dinosaurs out of their paddocks, or they wouldn't stop screaming no matter what was going on. It could be anything.
These 10 characters were certainly given a purpose, but that doesn't mean the audience had to fall in love with them. There are message boards devoted to how despised these characters were, and while it's often not the fault of the actors playing them, some of these are just the worst.
