Pokemon's First Appearance: Pokemon Gold, Silver & Crystal

There's a reason why gym leader Jasmine has an Ampharos a part of her squad. It's normally damaged by just about every type of attack, can do Hyper Beam, Thunder, Dynamic Punch and Fire Punch, and has good stamina and power. (And also has a base stat total of 500.) Ampharos' only problems is that it's weak against Ground attacks, and its speed isn't that great. Other than that, Ampharos is one of the best Electric-based Pokemon out there.
