With a serialized format and an endlessly creative writing team, Star Trek has given fans marvelous, novel aliens, worlds, and phenomenons since it debuted. One of the franchise's most successful series was Star Trek: The Next Generation, starring Patrick Stewart as Captain Picard. After The Original Series was prematurely cancelled, Gene Rodenberry was desperate to give his vision another go. Lucky for all Trekkies, he got that shot in the '80s.

Overall, fans agree early TNG could be a bit rocky. The series had cheesy plots, lackluster scientific intrigue, and Riker had way too many love interests. However, around mid-season 2, things started to pick up and the show became a cultural icon, spawning several other series, films, and books.

Though things improved, Star Trek definitely still had its flaws. Most often, they were bizarre, unsavory characters that somehow managed to get involved in whole episodes or more. The only thing that made them bearable was that the creators caught on pretty fast to what their fans didn't like. Of all the unsavory folk, Enterprise never showed of discussed them again past their initial episode.

However, devout Star Trek fans even the characters Star Trek tried to make them forget. After all, they can only never write about them again. The episode(s) they took part in? Writers and creators can't retroactively change those. For some fans, that's more than enough to burn a bad or illogical character into their minds.

Here are 25 Characters TNG Wants Us To Forget.

Dr. Katherine Pulaski

When Gates McFadden, actress for Dr. Crusher, had disputes with some of the creators, she was written off and replaced with Dr. Katherine Pulaski. However interesting Pulaski could be, some writing missteps and internal backlash spelled doom for the new doctor. For example, they put her at odds with fan favorite Data, questioning his humanity and autocracy a little too rudely. Furthermore, a different favorite, Patrick Stewart as dear Captain Picard, wanted McFadden back. Unfortunately, Pulaski only survived one season before creators axed her. A few fascinating episodes couldn't save her from the star power of Picard or Data.

Ronin

In what is named one of the worst Star Trek episodes ever, Dr. Beverly Crusher is slowly being possessed by her grandmother's ghost boyfriend. "Sub Rosa" irks a lot of fans, and the main source of that irking is Ronin, the main antagonist. However attractive he seems to be, his main goal is to get Beverly in his clutches to extend his own life.

Between being a creepy leach and the bizarre concept, Ronin is quickly discarded post-episode. Sure, he may have infected Beverly's mind and make her go a little ghost guy crazy and almost abandon ship, but definitely no therapy required.

Unfortunately for everyone involved, Ronin is tragically unforgettable.

Daimon Tog

Until Deep Space Nine, the Ferengi got a pretty horrible reputation as wanton schemesters with little respect for other people. Few episodes do this better that "Menage A Troi", where Deanna, her mother, and Riker get taken away by a Ferengi named Daimon Tog. Tog only wants them for Lwaxana's powerful Betazoid powers, thinking they'd make him a better businessman. Throughout the episode, Tog is creepy, rude, and generally lecherous. It's an uncomfortable watch, to say the least. Lucky for fans, the show quickly abandons him once the episode ends and no one sees the worst of the Ferengi ever again.

Leah Brahms

In desperation to fix the ship, Geordi once made a hologram representation of Enterprise's designer, Leah Brahms. As one does, he accidentally falls for her. Of course, when meeting the real her, things don't work out so well because, shockingly, she's more complex than what's in her file.

However, awkward Geordi charms himself out of the situation and Leah just leaves the ship as his friend. Though this is a big development in his character, realizing he shouldn't fall in love with ideas, the lesson's ignored almost immediately. He later falls in love with a girl just by snooping through her diary and pursues her, despite knowing she might be a dangerous shapeshifter.

Minuet

While Riker does have a problem falling for any pretty face that comes his way, there is a special place in his heart for the hologram, Minuet. During a program update from an alien race, the species takes the ship hostage. However, the more life-like program they created to keep Riker and Picard busy, Minuet, begins to become more real than expected.

Later, when "Romulans" try to trick Riker in a sort of mind prison, they use Minuet as his wife. With such an oddly deep bond to the holographic gal, it's odd those are the only two times he really mentions her.

Jenna D'Sora

On his road to humanity, Data had more than a few awkward missteps. However, few are quite as awkward as his brief romance with Jenna D'Sora. A fellow scientist and music lover, Data and Jenna grew to be close friends during their time on the Enterprise. When Jenna and her long time boyfriend, Jeff, broke up, though, the pair chose to try a romantic relationship.

Quickly, things began to go awry. Though Jenna was frustrated with Jeff's unemotional responses, Data's actual complete lack of emotion was problematic. He did his best, but the lack of ion behind his actions drove them apart. They broke up amicably and no one saw Jenna on Enterprise ever again.

Alkar

Star Trek: The Next Generation did its best to show the complex duality of politics, its goodness and its evils. One of the cringiest portrayals was Alkar, a galaxy-renowned mediator who was using the youth of women to keep himself alive longer. With the self-important, manipulative reasoning that using their lives saved more lives on warring planets, he was a real scumbag. He almost destroyed Deanna Troi with his antics.

Though he es away before the episode ends, no one talks about the implications of his secret life. Was he really all that good a mediator, or did his manipulative ways seep into that, too?

Selar

In "The Schizoid Man," Star Trek fans met a fascinating and beautiful young Vulcan woman named Selar. She was filling in for Dr. Pulaski as she is a different high-ranking medical officer on the ship. However, after this episode Selar never appears in person, only is mentioned in ing.

While the continual acknowledgment is good, Star Trek definitely wants fans to forget what she looked like. Why? Because the actress who plays Selar is the same actress who plays K'Ehleyr, Worf's paramour only 14 episodes later. Between a cool-headed, one-off Vulcan and the fiery half-Klingon ambassador, Star Trek would prefer you K'Ehleyr. She does have a kid with Worf, after all.

Brenna Odell

Sometimes Star Trek has a decidedly strange idea on the future. One of those cases is the Bringloidi, a group of human settlers that moved to a different planet and decided to become 1800's rural Ireland. Yes, you read that correctly.

Among all this madness is Brenna Odell, the daughter of their leader. Brash and unapologetic, her father may lead but she's the one who keeps a lot of it together. With pick up lines involving feet-washing, though, she certainly only makes the weird, Irish stereotype of an episode even more uncomfortable. Despite her sensual relationship with Riker, the show is happy to forget she ever was on the ship.

Paul Stubbs

When a lifetime of work is on the line, it's understandable for people to get a little testy. However, perhaps not as testy as Paul Stubbs. Dr. Stubbs ed the Enterprise team to launch a probe into a neutron star he'd spent all his life studying.

However, when Wesley Crusher's nanobots project goes awry and accidentally creates sentient life (yep, that happened) they take over his probe and plan to leave with it. Afraid of losing his probe, Stubbs plans to commit casual nanobot genocide to ensure the success of his lifelong dream.

Things worked out well for everyone, but maybe someone should be concerned about the mad scientist that almost destroyed a species.
