Meowth is unusual among other Pokémon for its ability to speak like humans. During the earlier episodes of the series, Meowth liked to think he was somewhat in charge of the group, and was responsible for many of its plans and objectives. Most of Meowth’s background story is explained in the anime episode "Go West, Young Meowth". Meowth came to Hollywood on the back of a truck after seeing a film called "That Darn Meowth" dreaming of good food as seen in the film. He eventually joined a gang of stray Meowth led by a Persian. One day, he fell in love with a female Meowth who let him know that she preferred being with humans to being with a street Pokémon. To impress her, Meowth learned to walk and speak so as to be as much like a human as possible. Afterwards, however, the female Meowth looked down on him even more than before. After Meowth joined Team Rocket, she was abandoned by her owner, and joined the same gang that Meowth left. Ultimately, she fell for the Persian that led the gang. Meowth is an integral part of the team, counting Jessie and James as his only real friends, but he is often excluded from the rapport between the two. When he lured Pikachu to their side in an episode, he seemed to have his own agenda as to what to do with it. Often, he explains why they should capture the main Pokémon of a particular episode, by indulging in an unrealistic fantasy of Giovanni’s reaction to their success, such as in, "Beg, Burrow, and Steal", when he suggests stealing Trapinch so Giovanni can use him to crack walnuts. It is possible this is an unhealthy coping mechanism, as James comments that these fantasies proved Meowth had "officially lost it". Meowth is essentially the "brains of the outfit" and appears to come up with the majority of the team’s plans; he seems to share his species’ thematic association with money, often being the one most concerned with practical issues such as the dismal state of the team’s finances. Because of this, Meowth is usually the one who operates Team Rocket’s Pokémon-stealing machinery, working in the background while Jessie and James confront the protagonists. Starting in the Johto season, Meowth learned to pick locks to aid their criminal lifestyle. He is also skilled at piloting the Team Rocket hot-air balloon (and other getaway vehicles). Among other things, he is also able to sing, dance, read, and write - skills that Pokémon rarely possess. Being able to understand what Pokémon as well as humans are saying, Meowth also often translates their speech for Jessie, James and other characters. Meowth was shown to care greatly for Misty's Togepi when it was an egg. He willingly battles for the right to raise it, and wishes Togepi happiness with its new owner. Later on he was infatuated by May's Skitty, and helped her escape, contrary to Jessie's plans. He has also remarked that if he had met Pikachu under different circumstances, they might have been friends. On occasion, Meowth befriends other Pokémon (usually ones that are outcasts like him) but by the end of the episode he is separated from his new companions. He also seems to have a good relationship with Jessie and James' Pokémon. In Pokémon Yellow, Meowth is one of the Pokémon that the player must defeat when fighting Jessie and James. This however runs contrary to the anime as he, unlike most Pokémon, is not trained or owned by either Jessie or James and rarely battles. One of the trophies in Super Smash Bros. Melee is "Team Rocket's Meowth". When viewed, it says that Meowth's dream is to become a rock star. This dream was also shown in one of the Japanese ending songs as well as a special CD released only in Japan. The plot of one Pokémon short revolved around him throwing a concert for his fellow Pokémon. In Pokémon Channel Team Rocket's Meowth acts like an emcee or newscaster. An armband he wears references a line from the Japanese motto. (Source: Wikipedia)
The male lead of the story. He is deeply infatuated with Yuuki and much of the series has him trying to confess to her. During the first several episodes, he comes into possession a pair of Yuuki's panties, which he spends time trying to return. Whenever he pictures Yuuki not wearing her panties or sees her naked, he has a tendency to get a nose bleed. When he finally confesses his love to Yuuki, she tells him she loves him...and everybody else. Yayoi, Sera, and Zero all harbor romantic feelings for him. When he was younger, he was accidentally hit by a falling spaceship and given a cyborg body. This allows him to transform into the warrior Cosmo Banchou, a parody of Tuxedo Kamen from Sailor Moon. The transformation is triggered whenever he experiences moments of intense sexual desire. By the end of the OVA, it appears he becomes engaged to Zero because of a galactic rule which may or maynot be true.
A twenty-five-year-old man on the run, being accused of a murder that he did not commit. He is interested in photography and takes pictures of everything he finds interesting, but never develops the film.
A rather eccentric, but intelligent high school student who tries committing suicide by jumping off of a building, only to be stopped after realizing that a man wearing a pair of white angel wings was taking pictures of him. He is then taken captive by the man, who is the fugitive Lee Hyuk-Soo, but finds himself willing to accompany him even after he was released as a hostage. He was picked on and avoided in school due to a malpractice case against his father, who is a doctor, concerning the performance of an illegal abortion on a minor which resulted in death. Because of the calamity that ensued, Han had to transfer schools several times, only to have the kids continue pick on him since his father was well-renowned. This drove him to try and commit suicide and run away with his kidnapper, Lee Hyuk-Soo.
Suneo is the fox-faced (inherited from his mother) rich kid who loves to flaunt his material wealth before everyone. He is often seen with Gian, serving as Gian's lackey while they bully Nobita together, though deep down he fears and despises him as much as everyone else. Some of the stories start with Suneo showing off some new video game or toy which evokes Nobita's envy. He has an extensive knowledge of science, and is a talented artist and designer. He has the habit to invite Gian and Shizuka to something or someplace, but always leave Nobita out with one excuse or another. In some scenes, Suneo is seen as a narcissist who loves to stare at himself in the mirror while telling himself that he is the most handsome guy in the world. He is still a bed-wetter and needs to wear diapers when he sleeps, despite being in the fourth grade. He considers this humiliating habit his secret weakness. Suneo is also very self-conscious about his height, being the shortest kid in his class. (Source: Wikipedia)
