Green (Japanese: グリーン Green) is Red's main rival in the Pokémon Pocket Monsters manga. He is based on Blue from the original Pokémon Red and Green. His full name is Kai Midorikawa (Japanese: 緑川 開 Kai Midorikawa), which contains the Japanese word for "green" (緑 midori).
Green's debut was in Introducing the Pokémon Clefairy, bumping into Red, whom he immediately recognizes. The two Trainers have a race to get there to Professor Oak's laboratory, as they end up starting on their Pokémon journey the same day. Green was able to get to the lab first as Red got caught up with a Nidoran♂. In the lab, Green chooses a Charmander with a fierce personality. Afterwards, he begins on his journey. Green ends up catching ten more Pokémon simultaneously. When he reached the Pokémon Center after Red rushes his Clefairy there, he shows Red eight Pokémon out of the ten that he caught as opposed to Red catching only one. He watches Red heal his Clefairy from outside and has his Charmander fling a bug at the Pokémon Center where Red is in order to annoy him. Green goes to the Pewter Gym sometime during Red's arrival to Pewter City where he and his Charmander get overwhelmed by Brock's Pokémon's strength. He leaves the Gym and tells Red to be careful when facing Brock.
After Red's challenge with Brock, Green then shows up in Red's campsite, catching a Golbat that was attacking Clefairy. Green turns around and leaves, mocking Red in the process. He joins Red in the search for the legendary Pokémon, Mew after it took the Moon Stone from Misty. Green continues the search with Red and it was a long one until Charmander runs past Red as it was able to find Mew. Green finds it in an abandoned water mill where it was revealed to be run by Bill and his assistant who is in fact a human in disguise as a Mew. However, Green, not noticing this, throws a Poké Ball at Bill's assistant but Bill blocks his Ball from catching Mew. This caused Clefairy to battle Charmander. During the battle, Charmander immediately goes to its Charizard stage, leaving Clefairy at a disadvantage. Bill shrinks Charizard but accidentally shrinks Clefairy as well in one of his machines. Green then gives up in catching Mew. As soon as both of the transformed subjects change back, Bill's hideous appearance causes Green and Red to run away. Afterwards, Green goes his separate ways.
Green returns in Catch That Pokémon Thief!! where he buys items to make his Pokémon stronger. He briefly tells Red about what happened after Clefairy foils the robbery. In the next chapter, he goes up to Red in a suit mocking him about how he wouldn't become good at the slot machines. However, this changed when Pikachu was able to get three 7's in a row. As a result, Green turns around and leaves. In Big Struggle with the Powerful Opponent Venusaur, Green is on a motorboat and has Charmander blast Red's normal boat to show them that Green is better than them. Red encounters him in The Life-or-Death Magic Duel at a restaurant. Professor Oak contacts him and Red and tells them about a legendary bird Pokémon residing in Seafoam Islands. Green goes there immediately and finds a cave in the next chapter. He trains Red as soon as he gets there in order for them to capture Articuno. Green encounters the Articuno but gets frozen by its Blizzard, leaving Red to handle the situation. After Articuno is caught, Green and the others are freed.
In Get The Flying Machine!!, after Blue beat Red in getting the flying machine, Green flies on his Charizard with both rivals telling Red about him not having anything for flight transportation. Green participates in the No. 1 Pokémon contest in Aim to be the No. 1 Pokémon! using his Meowth. Green's performance starts by having Meowth throw coins to the audience and then evolves into Persian. Persian then devolves back into a Meowth. The judges give him good comments about the performance. He participates in three other events afterwards, notably the baseball match that happened in Pokémon Baseball Tournament!!.
Green reappears in Bring Down the Strongest Pokémon!! where he witnesses the creation of Mewtwo done by Bill after Giovanni and his twin brother force him to do so. He competes in the curry cooking competition later on. After Red took on the Elite Four in Red VS Green?!, he trains with Green as he became the Champion. Green then reappears in The Pokémon Banana League, parts 1 and 2, where he and Red were battling for the Champion title. He was shown to have caught a Gengar and Koffing during that time.
During Where is Chikorita?!, he steals a Chikorita from Professor Oak but returns it to him at the end of the chapter.
Green returns after a long absence in Clefairy, Form Teacher Of Class 1P!! of the Pokémon Ruby-Sapphire manga. He cameos in that chapter and is wearing Blue's FRLG outfit.
In the Pocket Monsters BW manga, Green reappears again in PMBW31 and PMBW32.
Green takes Pokémon much more seriously, although has questionable ethics in attaining his goals. He has tried to stop Red from getting ahead from Green as seen in Part-Time Job At The Swimming Pool!! when he had Clefairy trip on Ditto in order to mess up.
