3 of the most controversial people to ever appear in Star Trek

Star Trek is one of the best franchises in the history of pop culture and science fiction at large. It's a franchise that features top-notch talents, some of the very best storylines, and characters that stand the test of time. It is about as perfect as something can truly be. Yet, nothing is ever truly perfect.

Starting with Gene Roddenberry, the series creator, and going through the franchise's history, the series has always been a constant melting pot with unique and different personalities. Sometimes those personalities weren't always the best. The original trio of names, Roddenberry, William Shatner, and Leonard Nimoy were all imperfect men.

Good men at their core, but flawed. As we all are. Some stories paint them in a less-than-ideal light. Roddenberry was very difficult to work with, to the point he attempted to sabotage the franchise. Shatner was known for being difficult to work with as well and was at times so self-conscious that others found his behavior off-putting. Nimoy had several issues in his home life, including issues with alcohol.

Yet, none of them were "bad" men. While most of the franchise featured a controversial name or two through its run, most of the core cast and crew, and the more notable guests, were good people. They marched for workers' rights, spoke out against injustices, and were largely just a force for good. Even if they faltered from time to time.

Yet, not all of them were good people. Some were downright awful, for one reason or another. Today, we're looking at three of the worst people to ever appear on screen.
