This will be fun, looking at characters who really aren't as great as their popularity suggests. No order in this one.
1. Tenten from Naruto
Tenten is the resident weapons master of Konoha and had so much potential only to be humiliated in the Chuunin exam and be thrown into the background despite standing on the same level as Rock Lee and Neji. She had practically no role afterwards.
2. Tyson Grainger from Beyblade
For the supposed leader of the Bladebreakers, he's a terrible leader, it's any wonder his much more popular teammates left for their own interests in G Revolution, not to mention he ignores much of the advice given by his team overall.
3. Usagi Tsukino from Sailor Moon
I'd forgive Usagi so much more if the original didn't make her so incompetent, needy and whiny, it's any wonder Precure destroyed this series in ratings.
4. Iona Hikawa/Cure Fortune from Happiness Charge Precure
Speaking of Precure, a Cure at worst is forgettable, generic or plain. Iona is a bitch; she blames Hime for all her problems despite the fact that it was her own fault that her sister got taken. Even when she joins the team, it's hard to forgive her for her behaviour.
5. Hatoko and Suzuka from Angelic Layer
She was built up as the main rival to Misaki and Hikaru and was wise above her years but she was defeated before given the chance and even burst into tears afterwards, child or not, you cannot build a character like that and then expect her to act her age afterwards.
6. Chao Lingshen from Negima
Supposedly Negi's descendant but her motives are confusing, does she want to reveal magic or not? Sadly this doesn't get answered. As for her non canon roles she's just a seat filler. Even her canon role is reduced to nothing once it ends which fills half the manga run.
7. Char Aznable from Gundam
He's the eternal rival of Amuro but looking on his history, he has an unhealthy obsession with underage girls. One out of possibly five female characters was actually an adult, the rest were teenagers.
8. Gary Oak from Pokemon
Was built to be Ash's eternal rival, he lost before Ash in the Kanto league, made little to no impact in 90% of his appearances, when he did battle Ash it was the best episodes of the franchise but after that his job was done. Paul from Sinnoh was a better rival.
9. Fuko Kirisawa from Flame of Recca
For the lone female fighter of team Hokage she's awful! Gullible enough to fall for enemy tricks twice, wasted Fujin's powers, got lost, trapped, brain washed multiple times and rescued by Raiha just as many times. Are you sure Fuko is meant to be the fighter? Yanagi is stronger despite not even being capable of fighting.
10. Future Trunks from Dragonballz
Controversial but justified, his only real contribution is killing Freiza. If you consider the Android 13 movie canon, he failed to mention six other androids next to 17 and 18, inadvertently unleashed Cell on the very timeline he tried to save, even when battling Cell he performed worse than Tien and even when he has to save another future he gets called out on all the times he messes with time and how frequently it brought about worse scenarios including attracting the attention of Babidi and Majin Buu triggering Super Saiyan Rage. It gives Vegeta much more father points when you consider the original Trunks to be a better character who even calls out his own future self.
