Blastoise and Venusaur can't even compare to Shillizard in terms of popularity. Normies love the generic fire-breathing dragon.
"Alain (Japanese: アラン Alan) is a recurring character who appeared in the Pokémon anime. He is a Pokémon Trainer seeking to defeat all Mega-Evolved Pokémon using his Mega Charizard X."
"Leon is known far and wide for taking part in the Gym Challenge at the tender age of 10 years old—and even more so for claiming victory in the Champion Cup on his first attempt. Ever since that victory, he and his partner Charizard have remained unbeaten in both League and exhibition matches."
