Pokemon Generations is an animated adaptation of the Pokemon video game series, created to celebrate the franchise's 20th anniversary. In contrast to the mainline Pokemon anime series that most are familiar with, Pokemon Generations is a Truer to the Text adaptation, making it more similar to the 2013's Pokemon Origins.
Another thing that makes Pokemon Generations different than the other adaptations of the franchise is that instead of centering around the protagonist of the games (or characters based on them), it tells various stories that happened in the games from the point of view of other characters, major or minor. Some of them are told exactly like what happened in the games, while others are more in the vein of "What if?" scenario. The stories themselves encompass the first six core series regions (Kanto, Johto, Hoenn, Sinnnoh, Unova and Kalos), with each of them getting 3 episodes.
The series is available through an online broadcast on the Pokemon official YouTube channel.
Tropes used in Pokémon Generations include:
Adaptational Badass: Gabby and Ty. In the original games, they're just reporters who interview trainers. In here, they're Intrepid Reporters who tried to get a secret data from the space facility and got away with it at the end of the episode.
Adaptational Heroism: Downplayed with Lance in Episode 4. While he's never a villain in the original games to begin with, his decision to knock out the enslaved Electrodes during the Mahogany raid might seem amoral to most. In this series, he frees them from the machine devices instead.
Adaptational Villainy: In the original Sinnoh-based games, the ghosts in the Old Chateau are harmless. In here, not so much.
Affably Evil: Like in the game he hails from, Lysandre is portrayed in Episode 16 as a polite yet stoic gentleman who wants to create a more peaceful world where conflict and theft are non existent... and just so happens to plan to do this by unleashing a 3,000 year old superweapon powered by this universe's God of Death and wiping out all people and Pokemon except for him and his henchmen, thus preventing the world from falling into chaos via overpopulation and greed- wait, what?
Alternate Continuity: Seems to be this to the other Pokemon adaptations, but especially the video games; while the stories are more grounded toward that continuity, they seem to branch more toward slightly different situations and details, especially the "What if?" stories.
Ambiguous Disorder: Whatever the case, something's just not right about Courtney. She seemingly has the gift of getting visions does not help the case...
Ambiguous Ending: Episode 10 ends with Cheryl and her Chansey screaming in terror as the ghost girl of the Old Chateau shows her terrifying shape. Wheter this is before her escort with the player character in Platinum ,later, or in a separate moment entirely is left hanging. In the former case, it might explain why she felt terrified with the mansion later on. In the latter cases, well...
Episode 7 saw Magma Admin Courtney getting a vision about Primal Groudon's awakening, in which it immediately destroyed its surrounding islands with Solar Beam and wiping out the Team Magma force that was in there, including Maxie and Tabitha.
Episode 8 has the awakening of Primal Kyogre, in which it caused a nightmarish heavy storm to hit the lands of Hoenn, and later implied to eat both Archie and Shelly.
Bolivian Army Ending: Episode 8 ends with Primal Kyogre launching itself toward the Aqua Submarine with its jaws gaping open, with both Archie and Shelly on board.
Cute and Psycho: Dear Arceus, Courtney. From her creepy speaking manners and her expressions toward Brendan during the "analyze" scene, something's definitely not right with this girl's head.
The tone in general, while still the lighthearted-adventurous variation in certain episodes, is definitely darker than most adaptation of the franchise.
Pokemon used as practical weapons are more indented, with an entire SWAT team and terrorist organizations taking advantage of them. While the former are more relieving, there's still the fact that people like Team Rocket and Team Plasma exist...
The terrorist groups are not glossed over and are more serious than their usual depictions.
Ghost Pokemon are depicted more closely to their original games dex data entries, in which they're more capable of doing terrifying deeds instead of just pulling harmless pranks.
And then there's also the legendary Pokemon, which are now presented as what they are in the original games- Most of them are creatures of mass destruction that can practically press the "End of the World" button when out of control.
Dragged Off to Hell: What Giratina decides to do to Cyrus. Cyrus doesn't mind, though.
Hotter and Sexier: Justified, as the series is aimed more toward the fans of the original games, most of which are already late-teen to adult by the time.
Although her appearance is more or less the same as in Omega Ruby and Alpha Sapphire, Magma Admin Courtney's dialogue toward Brendan at the end of Episode 7 has a lot of suggestive tones, with her facial expressions not helping.
Same with Aqua Admin Shelly. While she's already known among the fandom as quite a hottie in the original Ruby and Sapphire, the series ramps up her Fanservice vibe by giving her more risque expression and poses (including a Male Gaze and more pronounced curves.
In addition, the female Aqua Grunts are given more detailed midriff.
Downplayed with Cheryl. While she has more pronounced and delicate curves than her official game artwork and some of the close-ups of her eating can be rather suggestive, most of her scenes are played normally with her innocence played up more.
Parental Abandonment: Giovanni is shown in a flashback to have left his son, Silver in order to rebuild Team Rocket.
Pokémon-Speak: Averted. Pokemon are depicted with their cries from the original games.
Villainous Breakdown: During the standoff with his son in Episode 15, Ghetsis is eventually reduced to screaming at N in psychotic fury, calling him a tool.
