Pokémon

Pokémon is a video game series, anime, manga, and movie series that surrounds creatures called Pokémon and people who catch and raise them. Some of these people raise Pokémon and use them in battle—these people are known as trainers. Trainers can compete against other trainers to see which one is better than the other. There are some trainers in the Pokémon world who act as bosses in the Pokémon games named Gym Leaders. These Gym Leaders, upon defeat by the player, will give a badge to them. Most of the time, a badge will be necessary to progress in the games to prevent weak players from going into areas they weren't ready for. In generation seven (read more on generations below), the Gym Leaders function was no longer used.

Many things in the Pokémon world have been created in the name of Pokémon, such as the Poké Ball (a capsule used for catching Pokémon), PokéCenter (a clinic for Pokémon), and Poké Mart (a store for items relating to Pokémon).

The Pokémon Games
The Pokémon games are split into eight eras (with the eighth one not released yet) called "generations". Somewhat like with generations of people, the games in one generation would have their differences from a game in another generation, like the Pokémon count or included features.

The Pokémon count is at 151. All are new in Gen I.

Gen II

Characters
Goofball Bad Guys - Team Rocket's Jessie, James, and Meowth. This trio of goofs made their best tries at nabbing that not-so-rare-or-special Pikachu from that Ash Ketchum over the years. The amount of times they were BLASTING OFF AGAAAAAAAAAIN is beyond alarming as Realistic Reality says that even after their first blast-off, their landing would have broken many bones in their bodies and rendered them useless to their boss, Geovanni. A few more blast-offs and they'd be dead from sustaining so many injuries.

Joke-Sake Name - Ash Ketchum and a lot of Gym Leaders. Many of these people have names that are play-on-words of what they're affiliated with. An example of this is Ash's last name, Ketchum, sounds like "catch 'em", alluding to the franchise's earliest mantra, Gotta Catch 'Em All!.

The Main - Ash Ketchum. Ever since he began his dream of catching every single Porkyman in existence—even the legendaries, mythics, and otherwise annoying-to-catch 'mans—in his hometown Pallet Town with his mom Delia Ketchum, he's been the Main of the series' anime, movies, and some fan games.

Misc.
Real Life Ruins Everything - Some religious people have a problem with the entire idea of Pokémon evolving as they don't believe in it; PETA despises the idea of children using small animals (despite the fact not all Pokémon are small or animals) for "cockfights" and even went as far as to create their own parody of Pokémon Black and Whiteundefined. Fortunately, Pokémon fans have strongly retaliated against these remarks and attacks on the Pokémon franchise.

The Title Warned Us - You know, All! 'Em things you Gotta Catch?
