No, Jessie and James from the anime are not in Pokémon LeafGreen.
Jessy has had 10 failed partners in the last 2 months when she met james.
Jessie gets Wobbuffet after losing her Lickitung in a Pokemon Swap Meet in Johto.
In the manga Jessie and James get married in the end. They are not married in the anime series, just partnered together in Team Rocket. James has consistently complained about his unwanted fiancée Jessiebelle, although has has not been able to get through to her or his family that he wants nothing to do with her.
I agree, I've heard that they're both 17. Which could be more right as Jessie says so in the anime. It's most likely that they're around 17 or 18. Seeing as, in the beginning, Ash was 11, Misty probably around 12 or 13 and Brock was 15, I can't see Jessie and James being that much older..
in the anime it appears to be koffing or carnivine
Jessie from Team Rocket started out the anime show with a low level ekans. Over time, the Pokemon got much stronger and evolved into Arbok. As far as I know, she still has it.
Yes, Pokemon is an anime.
Yes Pokemon is considered an Action anime.
Because the manga were made by fans. The anime was made for young children and doesnt have any (confirmed) romance. The manga are more like doujinshi, really, so all kinds of things happen in them.
Pikachu is an anime character from the anime, Pokemon.
The answer to your question is quite simple, although not too obvious if you are a fan of only the anime.Yes, Kojiro (James) does care for Musashi (Jessie). Not only is this shown in very small doses during the anime, but towards the end of the manga, we come to find out that Jessie and James end up quitting Team Rocket, marrying, and starting a life of their own. This also includes Jessie's pregnancy which is not elaborated on, but clearly shown.Hope this helps :]
