Here I will فہرست off all the Pokémon Ash caught within the first 16 seasons of the anime, what season he caught them, what episode he caught them, where he caught them, and their original trainers (if they had a trainer before Ash). Here are the first 20.

Kanto (Original Series)

1. Pikachu (episode 1- Pokémon- I Choose You!)

Pikachu was Ash's starter Pokémon that he received from Professor Oak. He received Pikachu because he woke up late on the دن he was supposed to start his Pokémon training. Pikachu didn't like Ash AT ALL when Ash first got him, and was very disobedient, refusing to help Ash catch a Pidegy, laughing at Ash when Pidgey flew away, and laughing at Ash when a Ratata took food from his backpack. He began to listen to Ash when he saw Ash protecting him from a flock of angry Spearow. He is currently traveling with Ash in the Kalos Region.



2. Butterfree (episode 3- Ash Catches a Pokémon!)

Ash caught him as a Caterpie, but instead of battling Caterpie and weakening him first, Ash just threw a Pokémon and managed to get a lucky catch. When Caterpie was sent out to fight against Team Rocket, he evolved into Metapod. In the following episode "Challenge of the Samurai" he evolved into Butterfree. Ash released Butterfree in "Bye Bye Butterfree" so he could raise a family with the گلابی Butterfree. He is living with the گلابی Butterfree at an unknown loacation.



3. Pidgeot (episode 3- Ash catches a Pokémon!)

Ash caught Pidegot as a Pidgeotto in the Viridian Forest, the exact same place where he caught Caterpie, but the difference was he actually battled against Pidgeotto instead of just throwing a Pokéball. It evolved into Pidgeot in the episode "Pallett Party Panic" and at the end of the episode Ash released Pidgeot so it could protect a group of Pidgey and Pidgeotto from a flock of Fearow which is led سے طرف کی a Spearow. Pidgeot is currently in the Viridian Forest.



4. Bulbasaur (episode 10- Bulbasaur and the Hidden Village)

Ash met Bulbasaur at the Hidden Village where he was a guard determined to protect the other Pokémon that were living in the village because they were all injured یا had been abandoned سے طرف کی their trainer. Bulbasaur hated Ash, Misty, and Brock when he first met them, but after he witnessed them protecting the other Pokémon from Team Rocket they gained his trust, and he allowed Ash to battle him and Ash successfully caught him. He is currently acting as the peacekeeper for Professor Oak at his lab.



5. Charizard (episode 11- Charmander- the Stray Pokémon!)

Ash caught Charizard when he was a Charmander. Charmander had a trainer named Damian, but after Charmander lost in a battle, Damian left him on a rock promising to come back for him when he had no intention of doing so. At the end of the episode, Charmander learned to use Flamethrower, and Damian wanted to take him back, but Charmander saw that Damian didn't respect him, so he used Flamethrower on him making him run away. Charmander evolved into Charmelon in "March of the Exeggutor Squad" and after that he began disobeying Ash. He evolved into Charicard in "Attack of the Prehistoric Pokémon!" but was still disobedient towards Ash. It wasn't until the episode "Charizard Chills" that Charizard began to obey Ash after Ash helped him regain his strength after losing to a Poliwrath. He is currently at Professor Oak's lab while Ash travels in Kalos.



6. Squirtle (episode 12- Here Comes the Squirtle Squad!)

Ash and his دوستوں were traveling on their way to Vermillion City when they heard about a group of trouble making Squirtle called "The Squirtle Squad". Ash's Squirtle was the leader of the trouble making squad. After Ash saved him from being crushed سے طرف کی a rock, he decided to شامل میں Ash. He is currently back with the Squirtle Squad who are now firefighters that help out Officer Jenny.



7. Kingler (episode 13- Mystery at the Lighthouse)

Ash caught his Kingler as a Krabby on the ساحل سمندر, بیچ and his Pokéball was sent to Professor Oak's lab right away afterwards because Ash already had 6 Pokémon with him at the time, which is the maximum amount a trainer can have with them at one time. He evolved into Kingler in the episode "Round 1- Begin". He is currently at Professor Oak's lab.



8. Primeape (episode 25- Primeape Goes Bananas)

Ash and his دوستوں were traveling to Celadon City when a wild Mankey comes around and when they make Mankey angry, he steals Ash's hat which makes Ash furious. Soon afterwards, Team Rocket showed up, and after James kicked Mankey, he got angry and evolved into Primeape. Ash called Charmander out to battle against Primeape and he successfully defeated him allowing Ash to capture him. Ash and Primeape won a competition for Fighting types called "The P-1 Grand Prix" in the episode "The Punchy Pokémon" and after the competition Ash gave Primeape to a trainer named Anthony who Primeape is currently training with.



9. Muk (episode 30- Sparks Fly for Magenemit)

While Ash and his دوستوں were traveling through Gringey City Ash meets a group of Grimer led سے طرف کی Muk who have made the city so fifthly that it's a desolate wasteland. Ash battles Muk and manages to catch him (I'm just guessing that Muk is a male, although Muk's gender was never confirmed in the anime). He had to be sent to Professor Oak's lab because his Pokéball stunk so bad. He is still at Professor Oak's lab even though the stench he had before has been removed, and usually he can be seen smothering Professor Oak whenever Ash calls.



10. Tauros (x30) (EP035)

Most شائقین know about Ash's Tauros and that the episode he caught them in was banned from airing outside of Japan due to the immense amount of firearms in the episode being pointed at Ash, Kaiser, and even being fired at Team Rocket. There was a video of the episode on YouTube in Japanese with English subtitles, and I watched it once, and I think another reason the episode was banned was because Team Rocket held Kaiser hostage and forced him to tell them about the whereabouts of Diratini, and when he refused to talk James کہا something to him and the English subtitles translated that James told Kaiser "You are really starting to piss me off." That's not appropriate language for a children's show, so that could've been another reason the episode hasn't aired outside of Japan. Ash's Tauros are currently at Professor Oak's lab and he would use Tauros from time to time in battle, and usually when he returns to Kanto after a journey and goes to Professor Oak's lab such as in "The Dream Continues" all 30 of his Tauros are super excited to see him and they all trample him.



Orange Islands

11. Lapras (episode 84- The Lost Lapras)

After a while Ash gains Lapras' trust and he catches him. From that point on Lapras acted as the transportation from island to island up until Viva Las Lapras when he was finally reunited with his mother.



12. Snorlax (episode 95- Snack Attack)

As the gang continues traveling through the مالٹا, نارنگی Islands they stop on the first of the Seven چکوترا Islands. Ash is about to eat a چکوترا when a woman named Ruby accuses Ash of being a thief that has been stealing all the islands grapefruit. Ash explains to Ruby that he and his دوستوں just arrived on the island and Ruby apologizes. Once they find out the thief is actually a Snorlax Ash decides to capture him. With the help of Jigglypuff and her lullaby Ash is able to catch Snorlax, who falls asleep due to the lullaby, before falling asleep himself. Snorlax is currently at Professor Oak's lab while Ash travels in Kalos.



13. Heracross (episode 119- A Sappy Ending)

Team Rocket چرا لیا, چوری کی her and tried to convince her to شامل میں their side, but after Ash saved her she joined him instead, and this is also probably the biggest reason she fell in love with Ash and always tried to get his attention. In the episode Current Events, Team Rocket managed to catch her and then sent out Arbok and Victreebel commanding them to attack Ash. Seeing Ash in pain made Chikorita so worried and she evolved into Bayleef and saved Ash. In the following episode Turning Over a New Bayleef she attempted a few times to run into Ash's arms the way she had as a little Chikorita, resulting in Ash getting mad at her. While Ash was helping Brock set up the gangs lunch Totodile began dancing around right اگلے to Ash, attempting to get Ash's attention. Bayleef then wanted to run into Ash's arms but she imagined Ash spilling the food and yelling at her, so she walked up to him as cautiously as she could, but he still yelled at her and the last thing he کہا to her was "Get away from me and stay away from me."

Later on, Ash and his دوستوں arrived and Ash attempted to apologize to Bayleef numerous times, but she wouldn't forgive him. It wasn't until Ash helped free Bayleef and the woman's Pokémon from Team Rocket that Bayleef began to realize Ash was truly sorry for yelling at her and she helped him to free the other Pokémon and forgave Ash.
