After obtaining all eight Kanto Gym Badges and making it through Victory Road, you will arrive to Indigo Plateau where the Pokemon League is found. The Pokemon League is comprised of the Elite Four and Kanto Region Champion, five trainers you must defeat consecutively in order to become the next Champion. These trainers are the best of the best found within the Kanto Region, so be prepared for five difficult Pokemon Battles in a row.
The first Elite Four Member is none other than Lorelei, the same who specializes in using Ice Type Pokemon. Ice Type Pokemon are usually weak against Fire Type Attacks and Steel Type Attacks; however, that really isn't the case with Lorelei. This is because four of her five Pokemon (Dewgong, Cloyster, Slowbro, Lapras) are all part Water Types, neutralizing the effects of both Fire Type and Steel Type Attacks. With this in mind, it would actually be best to have at least one Electric Type on your Pokemon Team (as well as a few Pokemon with an Electric Type Attack) in order to defeat Lorelei.
