Ash was given Pikachu by Professor Oak as the original Kanto starter Pokemon had been taken. Originally, Pikachu would not listen to Ash and constantly shocked him. However, after accidentally angering a flock of Spearow, Pikachu had a change of heart when it saw Ash defend him. Since then, Pikachu has assisted and been very successful in many of Ash's wins and over time has adopted Ash's mannerisms. Pikachu does not want to be in its Poké Ball so it stays out all the time, often riding on Ash's shoulder or head. Pikachu's Moves: ThunderShock, Thunderbolt, Agility, Quick Attack, Thunder, Double-Edge, Tackle, Leer, Iron Tail, Volt Tackle and Electro Ball.
