First Appearance: Episode 3 ("Ash Catches a Pokemon")
Evolves: Metapod: Episode 3 ("Ash Catches a Pokemon"), Butterfree: Episode 4 ("Challenge of the Samurai")
Leaves: Episode 21 ("Bye Bye Butterfree")



Caterpie is the first Pokemon that Ash caught by himself. Caterpie was in the wild when Ash simply threw a Poke Ball at it and caught it, and the rest, as they say, is Pokemon history. It was caught without being weakened because it was already a weakling to begin with. Caterpie shows its strength later by defeating the Team Rocket's Pokemon, Ekans, Koffing, and Meowth all by itself and then evolving into Metapod. Metapod can only use the "Harden" attack, so it was pretty useless in battle. It was captured by some Beedrill and when it was released it evolved into Butterfree. It left to be with a female Butterfree, and the end of that episode had a short montage of Butterfree clips.

#17 and 18: Pidgeotto/Pidgeot
First Appearance: Episode 3 ("Ash Catches a Pokemon")
Evolves: Pidgeot: Episode 81 ("Pallet Party Panic")
Leaves: Episode 81 ("Pallet Party Panic")
Pidgeotto is the second Pokemon Ash catches. It is a bird-type Pokemon who is very loyal to Ash. Most people feel sorry for it because all it ever does is blow away Koffing/Weezing's smoke screen and punch holes in Team Rocket's Meowth Balloon, and think Pidgeotto could've been treated better. It leaves in Episode 81 ("Pallet Party Panic") after evolving to Pidgeot to help a flock of Pidgey and Pidgeotto defend itself from the threats of a gang of Spearow and Fearow.
#1 BulbasaurFirst Appearance: Episode 10 ("Bulbasaur and the Hidden Village")
Bulbasaur is the first of the three starter Pokemon from the Red and Blue video games Ash gets in the TV show. It was raised in a village for sick Pokemon, acting as their bodyguard. Bulbasaur decides to join Ash after he helps his village defend itself against an attack by Team Rocket. Bulbasaur is a stubborn Pokemon who refuses to lose. It uses its Vine Whip to attack its foes or as a rope (for saving people falling off cliffs). It refuses to evolve into Ivysaur in Episode 51 ("Bulbasaur's Mysterious Garden").
First Appearance: Episode 11 ("Charmander, the Stray Pokemon")
Evolves: Charmeleon: Episode 43 ("The March of the Exeggutor Squad"),
Charizard: Episode 46 ("Attack of the Prehistoric Pokemon")
Leaves: Episode 134 ("Charizard's Burning Ambitions")



Charmander was abandoned by its trainer. The trainer kept promising to come back for it, but it never did. Charmander, being the loyal Pokemon it was, waited for weeks where its trainer told it to stay, but he never came. Ash found it, and after convincing it that its trainer was no good, Charmander decided to stay with Ash, Misty, and Brock. Charmander, a fire-type, will die if the flame on its tail goes out. Once it evolved into Charmeleon, it stopped obeying Ash. It quickly evolved into Charizard about three episodes later but doesn't start to obey Ash until halfway through the Orange League episodes (to be more specific, in Episode 105, "Charizard Chills"). Charizard is one of the most popular Pokemon because it is so strong, and finding a Trading Card Game card of Charizard is next to impossible. Charizard leaves Ash and the gang in the Johto League to train with other Charizard.
#7 Squirtle
First Appearance: Episode 12 ("Here Comes the Squirtle Squad")
Leaves: Episode 147 ("The Fire-ing Squad")
Squirtle used to belong to the Squirtle Squad, a gang of Squirtle abandoned by their trainers. It was the leader of the gang who would pull pranks on all the people in the town. It joined Ash, Misty, and Brock after Ash helped the Squirtle Squad against Team Rocket. Squirtle is the first water-type Pokemon of Ash's group, and is the only one of the three starter Pokemon from Red and Blue in the TV show who hadn't gotten enough experience to try to evolve to Wartortle (Charmander evolves twice while Bulbasaur had enough experience to evolve, but decided not to). It left Ash in Episode 147, "The Fire-ing Squad" to re-join the Squirtle Squad after it helped then defeat the defending Pokemon Fire and Rescue Grand Prix, Team Wartortle.

#98 and 99: Krabby/Kingler
First Appearance: Episode 13 ("Mystery at the Lighthouse")
Evolves: Kingler: Episode 75 ("Round One--Begin!")
Krabby is the sixth Pokemon Ash catches. He is sad that he has only six Pokemon at any given time and catches Krabby just to increase the number of Pokemon he has (Obviously so he can brag about it to Gary). Krabby stays with Professor Oak most of the time, drinking tea and making poetry with the doctor. Krabby's very first battle ever is in Ash's first Indigo Pokemon League Battle, and in that battle, it evolves into a Kingler. Kingler defeats all three Pokemon, Exeggutor, Seadra, and Golbat and wins Ash his first League victory en route to a top sixteen finish. It's rarely seen after the Pokemon League Competition.
#57: Primeape
First Appearance: Episode 25 ("Primeape Goes Bananas")
Leaves: Episode 29 ("The Punchy Pokemon")
Primeape used to be a Mankey before Ash caught it. It was lured to Ash and the gang by Brock's delicious-smelling donuts and then it stole Ash's hat. Ash tried desperately to get it back because the hat is an official Pokemon League Expo hat--and therefore hard to come by--but he is unable to. In his attempts to retrieve his irreplacable hat, Mankey evolves into Primeape. Ash manages to catch both the hat and the Primeape after being beaten up by it, but it won't obey Ash (much like Charmeleon/Charizard would later). Only during the P-1 Grand Prix did Primeape start to obey Ash. It was in this episode that Primeape stays behind to train to become a P-1 champ.
#128: TaurosFirst Appearance: Episode 35 ("The Legend of Dratini") (Japan), Episode 65 ("Showdown at the Po-Ke Corral") (US)
You're probably wondering why I have two episode title for Tauros's First Appearance. Well, Ash catches Tauros by accident in "The Legend of Dratini," one of two episodes from the show's first season in Japan that is yet to air in the US. He tries to catch a bunch of different Pokemon in the Safari Zone, but a Tauros would always get in the path of the Safari Zone and get itself captured instead. Ash probably has about 20 Tauros, enough to have his own private stampede. In its first US episode, Episode 65 ("Showdown at the Po-Ke Corral"), Ash's herd of Tauros stops Team Rocket from seizing Professor Oak's laboratory. Tauros is used off and on throughout the course of the series. Ash uses it at the end of the Orange League (Episode 112, "Enter the Dragonite") to fight a Dragonite, after defeating a Venusaur, but the Dragonite beats it with a Thunder attack. It is also used in the Johto League (Episode 146, "Tricks of the Trade") to beat other Tauros at a festival. Ash wins all the battles and has to send it back to Professor Oak's place to stop people from wanting to try to trade for his Tauros.
#131: Lapras
First Appearance: Episode 84 ("The Lost Lapras")
Leaves: Episode 113 ("Viva Las Lapras")
Lapras is captured by Ash when he first meets Tracey. Lapras is bonded by a bunch of punks, and Satoshi rescues it with the help of Tracey. It is later captured by Team Rocket, but Ash saves it again, this time keeping it. Lapras is used mainly to ferry Ash, Misty, and Tracey around in the Orange League. It helps Ash win his first Orange League battle with Cissy by using its Ice Beam to beat her Blastoise in a wave-riding contest. Ash's Lapras isn't the only Lapras the gang has encountered. In the Christmas Special, "Holiday Hi-Jynx!" a telepathic Lapras belonging to Santa Claus brings Ash, Misty, Brock, and Santa's Jynx to the North Pole. There, they meet with Team Rocket and battle, saving Christmas. Lapras are known to be intelligent and powerful.
#143 SnorlaxFirst Appearance: Episode 94 ("Snack Attack")
Snorlax is a big Pokemon (you'd be big too if you weighed 1,014 pounds!) which usually sleeps all the time. Ash met a Snorlax earlier in Episode 41 ("Wake Up, Snorlax!"). That Snorlax was blocking the way of a river, stopping the flow of water to a nearby town. Since water is essential to life, Ash had to get it out of the way. He couldn't catch it or move it, so he had to try to wake it up. After a while, he discovered that only a Poke Flute belonging to an old hippie can wake up a Snorlax. Fast forward to the Orange League. Snorlax was stripping this chain of islands of its fruit, so to stop it, Ash catches it. Ash doesn't use Snorlax very much. Snorlax can actually become very powerful if you train them well, but we all know Ash isn't about to do THAT.
#214: HeracrossFirst Appearance: Episode 119 ("A Sappy Ending")
Heracross is a beetle-type Pokemon. It is the first Gold-Silver pokemon Ash catches. Heracross really loves tree sap, or anything else sweet, for that matter. It's a powerful Pokemon, using the horn on its head to toss its opponents. Heracross is used now and again and is eventually given to a young boy at the Pokemon Trading Festival so that he may do a school project on it. The boy promises to give Heracross back, but don't count on Ash to come back for it (he never did come back for Primeape...)
#152: ChikoritaFirst Appearance: Episode 126 ("Chikorita Rescue")
Chikorita is the first of the three starter Pokemon in the Johto League. Chikorita is a grass-type with attacks similar to Bulbasaur's, and is known for learning powerful grass-type attacks, like Razor Leaf and Solar Beam, very early. Ash's Chikorita has a crush on its trainer and is constantly trying to get his attention. Will it replace Bulbasaur? Only time will tell.
#155 CyndaquilFirst Appearance: Episode 141 ("Good 'Quil Hunting")
Cyndaquil is the second of the new starter Pokemon Ash catches. Ash saw a wild Cyndaquil, and follows it deep into the forest, so deep that he loses Brock and Misty. Team Rocket tries to capture it, so Ash sends out Pikachu, Chikorita, and Heracross to fight it, but they aren't powerful enough. However, Cyndaquil's fire attack is more powerful than the three Pokemon and it wins. Cyndaquil then decides to stay with Ash. It is the fire-type of the game, sort of filling the void left by Charizard seven episodes ago. In fact, once Ash gets Cyndaquil, he kind of forgets about Charizard until it leaves later in the Johto League. Cyndaquil must wait for the flame on its back to ignite before it can attack.
#158: TotodileFirst Appearance: Episode 151 ("The Totodile Duel")
Totodile is a water-type alligator Pokemon. When it is first seen, Misty, being a water-Pokemon trainer, wanted to keep it for herself, but Ash wanted it, too. In a mini-tounament similar to the one held for Togepi (in Episode 50, "Who Gets To Keep Togepi?"), Misty and Ash fight for the right to keep Totodile, and Ash wins. Totodile loves to dance and is constantly happy. Somehow, Ash's Totodile is the Pokemon equivalent of Brock.
#164 NoctowlFirst Appearance: Episode 164 ("Foul Play")
On his way to Goldenrod City, Ash encounters a special Noctowl. This particular Pokemon is special because of its unusual color and size, as well as its above-average intelligence. The Pokemon is pursued by a man who plans to use traps to capture it instead of Poke Balls, but the owl Pokemon still manages to escape. After Team Rocket's attempt to capture Noctowl is foiled by Ash, the bird pokemon decides to challenge the young trainer. Ash's Pikachu battles, and of course, wins. Ash wins the respect of Noctowl and captures it, adding it to his team. Noctowl is the evolved form of Hoothoot. It's one of the stronger bird Pokemon in the game and is a useful member of your team. Ash hasn't really used Noctowl much, just like in the battle with Morty, the Ecruteak City Gym leader.
