I mostly took advantage of it learning practictly every move. It's type is electric beacause it has only one weakness, ground, wich is covered by it's moveset. Focus Blast covers 5 diffrent types, wich are normal, ice, dark, rock, and steel.Ice Beam also covers a lot of types wich include grass, it's weakness ground,flying, and dragon types.Earthquake also covers a lot, a total of 3, these types are fire, electric, and poison. PAyback I put in here to cover two types on the E4 that are ghost and psychic.With this moveset and type, this Pokemon has 1 weakness wich is covered by one of it's moves. It also covers every type but
3 wich are water, fighting, and bug types.
