Elite Four Member: Lance
Just look who it is! Of all the trainers that could be the champion, Lance was the obvious choice. Even so, he proves to be a formidable final test in the Elite Four challenge. Such a strong trainer has a befittingly balanced team. Using Gyarados, Charizard, three Dragonites, and an Aerodactyl, Lance doesn't hold back. Commencing the match is Gyarados, who will set off a rain storm with Rain Dance to boost its Surf and make Dragonite's Thunder never miss. Kingdra will be your best friend for the rest of the time, starting with Charizard, who has a powerful Flamethrower attack along with Wing Attack and Hyper Beam for extra coverage. Surf on Kingdra should knock it out in one hit, especially if Gyarados's rainstorm is still on the field. Aerodactyl is next and can also be taken out with Surf, though Rock Slide and Wing Attack might put a dent in your Kingdra if its slower. Dragonite is next, the first of a triumvirate Lance has with different movesets to throw you off. If either of the Level 47s come out, be careful of Thunder Wave, which can slow you down, and Twister, which can knock you out. Counter it with Blizzard or Dragonbreath if you have those moves. Kingdra shouldn't have too much trouble due to its natural bulk and the weak nature of Twister, but once the final Dragonite comes out get ready for a fight. Outrage has the raw power to knock out an entire team, and the only thing stopping it from doing so is the confusion Dragonite suffers on the second or third turn of using it. Steelix or Forretress might be able to handle the hits as Steel-types are the only thing to resist Dragon-type attacks, so consider using them. Punish the Dragonite with a strong Ice-type or Dragon-type move of your own to end the battle and claim the title of League champion.
