Come on, guys! Let me describe The Team Wannabe here! I can be a great troper!
A character wants to be part of some group, whether a gang, club, or being a superhero's sidekick. They will follow them around constantly to the point of stalking. They will hang around wherever they hang around. They will keep begging and pleading until they get in. Sometimes they even might, but usually they just stay the wannabe since Status Quo Is God. In a few cases they might get spurred enough to start to resent the group that rejected them, becoming a villain (or hero, if the group turns out to be evil).
The Tagalong Kid is often this. An Ascended Fanboy is often a former wannabe.
A Sister Trope to Leader Wannabe.
Compare Never Be a Hero, I Just Want to Be Special, Hero with an F in Good, The Chosen Wannabe.
Contrast The Drag-Along.
Compare/Contrast Jumped at the Call, Honorary True Companion, 11th-Hour Ranger.
- In Gall Force, Mitty is the Tagalong Kid variant. Sandy allows her to follow them because she's the local expert on where the best hiding places are.
- In Saint Beast, Shiva is desperate to enter the Saint Beast rank to be close to Judas, and even nearly gets another candidate killed over it. He ends up the only contestant who doesn't get in because of this, and his later petitions to be let into the group are shot down for the same reason.
- Yukari from Girls und Panzer is a big tank otaku who really wants to join the school's tank club and particularly Miho Nishizaki's crew, Miho being the younger sister of a famous family of tank commanders. She becomes an Ascended Fangirl pretty fast.
- William of Log Horizon wanted desperately to join Debauchery Tea Party while leveling his character, but they disbanded before he had a chance. Even after he formed a highly successful guild of his own he still resented the Party for not waiting for him. He grows out of it after going on a raid with Shiroe, after which he asks to add him to his friends list.
- Hetalia: Axis Powers: The Baltic state Estonia really wishes he was the sixth Nordic member, to the point that he usually goes around introducing himself as such. He also attends their meetings, invited or not.
- Romania is a huge fan of Ancient Rome, and considers himself to be one of his descendants (and thus an Italy brother). He tries to get acknowledged as such at one point, only for South Italy (also known as Italy Romano) to shoot him down immediately.
- Jimmy Olsen always wanted to be a superhero like Superman, but he doesn't exactly gain much respect from the other superheroes. Even with the countless times he gains and loses superpowers unexpectedly, no one seems to bat an eye at him.
- In an issue of Generation X, it's revealed that The Toad once tried joining the Hellfire Club's Inner Circle. He was later given shelter by Emma Frost because she felt sorry for him after the Inner Circle's members laughed so hard at him.
- In Runaways (2015), Molly is this to the Night Witches - Jubilee is not keen on having an 11-year-old in her gang. She later gets in after Pixie's death creates a vacancy.
- Deadpool is this to the X-Men. They've continuously turned him down; not only because he's not actually a mutant, but because they (like 99% of the superhuman community) find him extremely annoying (well, that and the whole "killing people for money" thing puts them off).
- Hitman (1993): Tommy Monaghan applies for a spot on the Justice League, mentioning that he kills people for money. When turned down, he helps out the next applicant by telling him not to mention money. However, it's subverted as he had no real intention of joining the Justice League: he was just there to look at Wonder Woman with his X-Ray Vision.
Now I can die a happy man.
- In Voyages of the Wild Sea Horse, the giant Ahab tried to join the original Giant Warrior Pirates but was refused for being too young. He's still sore about this a century later and is trying to recruit a new pirate crew to free Dorry and Brogy so he can be part of the new Giant Warrior Pirates.
- Syndrome of The Incredibles is an example. He was a Tagalong Kid who wanted to be Mr. Incredible's sidekick. He tried numerous times only for Mr. Incredible to brush him off and state that he works alone. This led "Buddy" to have a Broken Pedestal moment and signified his Start of Darkness. He spends the rest of his life orchestrating his Roaring Rampage of Revenge.
- Anybodys of West Side Story really wants to join the Jets.
- Katsushiro from Seven Samurai.
- The naive young gun Chico from The Magnificent Seven, a Composite Character of Katsushiro and the other Seven Samurai team wannabe, Kikuchiyo.
- The Kid from The Matrix, he wants to be like Neo, but Neo states he's better than that, he freed himself after all.
- John McClane becomes this in A Good Day to Die Hard because of his stubborn obsession to protect his son, much to that son's annoyance.
- In Deadpool 2 Dopinder wants to be a mercenary killer, but is treated as a Janitor by Weasel. He does eventually realize he's not the best in a direct fight. Though he can run over child abusers with his cab.
- Kirie in Ai no Kusabi was this before taking the Sixth Ranger Traitor route after taking one Pretender Diss after another from the other gang members.
- Chang in the second season of Community wants to be part of the study group.
- John Cleese in the Monty Python Abbatoir sketch, which rails against the Freemasons who rejected his membership application.
- Roy Harper spends late Season 1 to the middle of Season 2 relentlessly pursuing Oliver in his vigilante activities just so he can be his accomplice. Oliver initially hates the idea, but Roy being injected with Mirakuru forces him to take him in for closer monitoring.
- Laurel Lance from the end of Season 2 desperately tries to join Oliver Queen's crime-fighting circle - despite the fact that essentially the first thing they told her was she had no place in 'Team Arrow'. Given the team are a group of highly skilled fighters and genius level hackers, who view each other as family, while Laurel's only connection is being Oliver's turbulent ex-girlfriend, it's not surprising they're wary of her (her almost rotting Oliver to the cops also did not help). To add insult to injury, she only knows about his secret identity because a villain told her, while Oliver invited everyone else in because he trusted them. By the end of Season 3 Laurel has undergone enough training to be useful, though most of the team are gone by that point. note Tragically, everyone's hesitancy about letting her become a vigilante is justified in Season 4, when she's killed in the field.
- Malcolm Merlyn is a manipulative take of this trope, using schemes to force Oliver and his gang to cooperate with him on numerous occasions.
- In Hi-de-Hi! Peggy's entire character arc was her desperately trying to join the camp entertainers, The Yellowcoats. Many a Zany Scheme was attempted in this aim.

- Doctor Who: Adric, the first companion to be introduced in the Eighties, is first seen trying to get into the gang of teenagers (led by his older brother, Varsh) who have broken away from mainstream Alzarian society.
- A young Magnum TOKYO desperately wanted to join the Dancing Fools in World Championship Wrestling, but was kicked off for his efforts.
- Diana Allers in Mass Effect 3. A reporter for the Alliance News Network, she begs Commander Shepard to become part of the crew of the Normandy, positioning her reporting skills as vital to the war effort. Her overall contribution to both the story and War Assets system is very minor, and the player can choose to accept or reject her proposal.

There's a series of quests throughout the game to help her out of the various scrapes she gets into. Completing her entire quest chain averts this trope by not only letting her join BLADE, but becoming a party member.
- Reynold, civilian contractor of the Cheat Commandos, insists that he would be "a good mission guy", but the Commandos proper treat him with derision and dismiss him - when they're not locking him up and starving him, anyway.

- Marty (Mega-Girl), in the Whateley Universe, wants to become one of the Empire City Guard. She keeps trying to fight with them and they keep telling her parents what she's been up to. She's an extremely powerful Flying Brick but she's a sophomore in high school and she can't legally be a superhero until she's eighteen. Meanwhile, the Empire City Guard is the premier superhero team in New York City.
- Princess Morbucks in The Powerpuff Girls (1998) wanted to be a Powerpuff Girl ever since her debut episode, but only so she could have superpowers like them. When she's not out to destroy them, she's constantly scheming her way to get her way and be a Powerpuff Girl, but to no avail.
