The final test of any trainer in the Pokemon series is to take on the region's Champion in order to prove that they are the best of the best. Pokemon fans are likely familiar with the difficulty of these battles that challenge them to put their teams to the test against the strongest trainers in the game. However, some Pokemon Champions are far more memorable than others, whether that's due to their difficult nature, their involvement in the game's main story, or simply the effectiveness of their design.
