Name: Pikachu
Age: Unknown
Species: Pikachu
Gender: Male
Trainer (if wild leave blank): Ash Ketchum
Persoanlity: Pikachu is extremely loyal to Ash, and while he is not always immediately trusting of strangers, he is generally friendly to humans and Pokémon alike. He acted as a guardian and big brother to Misty's Togepi, and has been seen mediating and even breaking up fights among other Pokémon, such as in Pikachu's Vacation. In Mewtwo Strikes Back, Pikachu, Meowth, and Meowth's clone were the only Pokémon not to participate in the giant battle; Pikachu stood motionless as his clone repeatedly slapped his face. Contrary to his distrusting nature, Pikachu took a liking to Misty very early in the series, and he has retained this liking of Misty throughout the series, such as when he was very happy to see her in The Scheme Team. During the Hoenn saga, Pikachu temporarily developed amnesia and sided with Team Rocket for a while. On several occasions, Pikachu has developed an "electric flu" causing him to become overcharged, and extremely powerful. During these instances, Pikachu will sometimes accidentally let off electric outbursts which can be set off on anyone, including Ash. In all of these cases, Pikachu did not intentionally mean harm upon anyone. As shown in a handful of episodes, the first being Showdown at Dark City, Pikachu has a special fondness for ketchup, but he will eat and enjoy almost any other human or Pokémon food. A running joke in the anime also seems to be Pikachu using Thunderbolt at the beginning of each series to destroy a female companion's bike or shock the companion herself. This has happened to Misty, May, Dawn, Iris and Bonnie. Pikachu, like his Trainer, is always happy to battle. He often tries his very best, but when he loses, he doesn't complain or feel bad about himself, especially when Ash reassures him. Ash and Pikachu are almost identical personality-wise, and thus are the perfect match for one another, and most others agree, with the exception of Burgundy, who in A Connoisseur's Revenge! said that Ash had a terrible relationship with all of his Pokémon, though this is more due to her inexperience in determining relationship. In general, Pikachu as a species is not particularly powerful, but Ash's Pikachu is an anomaly, overcoming odds in battle numerous times. In Pokémon Emergency!, Meowth remarked that Pikachu's power "far exceeds its evolutionary level". In Showdown in Pewter City, he defeated Brock's Onix with an Electric-type attack that triggered the sprinkler system causing Onix to be drenched in water, one of its weaknesses. Ash's Pikachu has also defeated very powerful Pokémon that Ash's other Pokémon were unable to, such as Dragonite and Metagross. He was also the second of Ash's Pokémon to defeat a legendary Pokémon in battle, defeating Brandon's Regice to win the Brave Symbol. He later fought Tobias' Latios to a draw in the the semi-finals of the Lily of the Valley Conference. He has helped Ash win innumerable battles and Gym and League matches. The possibility of evolving into Raichu was first raised in the episode Electric Shock Showdown. After suffering a crushing defeat by Lt. Surge's Raichu, Nurse Joy presented Ash with a Thunder Stone. Ash allowed Pikachu to decide, but smacked it away with his tail, choosing to become stronger as he is, and defeated Raichu using its superior speed. In the Sinnoh region, Pikachu battled a Raichu belonging to a trainer named Sho. The two were evenly matched, until Raichu used Hyper Beam to secure victory, a move Pikachu could not learn. At a Pokémon Center, Ash revealed that he kept the Thunder Stone he acquired in Vermilion City in case Pikachu changed his mind about evolving. Once again, Pikachu chose not to evolve, and defeated Sho's Raichu in a rematch with a combination of speed and spinning techniques learned from Dawn. In the interim, Team Rocket stole the Thunder Stone, as they also liked Pikachu to stay as he is.
