Star Trek has a wide array of major names that fans flock to. Mostly, these are the captains. The types of characters that you build show around. Other times, secondary characters take over and dominate the fandom. People like Seven of Nine and Worf come to mind. Yet, while popular, these secondary characters aren't really the ones you want to build around.
Not after they've starred alongside other major names. They have their stories told, albeit not as the primary focus, but they get seen. They feel like complete characters. Yet, what about the quieter characters in the background who seem like interesting characters but we rarely get to see a lot of them?
Those are characters we'd like to see get their own shows. So which characters deserve their own shows after a season or more in the background?
Harry Kim
He had some really cool episodes in Star Trek: Voyager, but Harry Kim really didn't evolve on the show. He started the series as a single ensign and ended it the same way. Everyone else around him got promoted, fell in love, had kids, and the like, but Harry? Nothing. Coming back into a series where Kim, now a battle-hardened veteran recounts the stories of his career up until that point could be unique and interesting. Kim, the former ensign, is now maybe a captain or even more, and maybe he's left Starfleet. Maybe he's a bounty hunter or a rebel leader. Something about him really works when you go beyond the bright-eyed, bushy-tailed rookie he was on the bridge of Voyager.
George Kirk
The lesser-known brother of James T. Kirk, George Kirk is a science officer who's always been in his brother's shadow. We know he dies in the Original Series, but what about his life before then? We've seen some of his life play out on Strange New Worlds, but there's still so much more to him. More importantly, what if George doesn't actually die? What if his death was a cover-up for something more? Sure would be interesting to explore that.
Katherine Pulaski
Coming into the fold during Star Trek: The Next Generation's second season, Katherine Pulaski is a hardnosed doctor who really isn't interested in androids like Data. But why? We know a little bit of her back story and her dislike of droids, but what if there was a deeper reason? What exactly do we know about Katherine Pulaski?
