According to a poll on the IGN website, the most popular Pokemon are Charizard, Mewtwo, Blastoise, Lugia and Dragonite. A similar poll on the Dorkly website determined that Charizard, Mewtwo, Blastoise, Mew and Gengar were the top five most popular Pokemon. Other popular Pokemon on both websites include Scizor, Entei, Alakazam, Gyrados and Rayquaza.
Both websites listed Charizard, Mewtwo and Blastoise as the top three most popular Pokemon. Charizard, the most popular Pokemon, is from the first Pokemon generation and is a fire/flying type. To obtain a Charizard, trainers can evolve a Charmander into a Charmeleon and then a Charizard. According to Pokedex entries, Charizard spits fire that is hot enough to melt boulders, can fly close to an altitude of 4,600 feet and may cause forest fires by blowing flames.
Mewtwo, another popular Pokemon introduced in generation one, is a psychic type. Mewtwo was genetically engineered by scientists using DNA from another Pokemon, Mew. According to the Pokemon website, the scientists who created Mewtwo failed to give him a passionate heart.
Another first generation Pokemon, Blastoise is number three on the most popular list. Blastoise is a giant turtle, about five feet tall, with dual cannons protruding from his shell. Blastoise is a water-type Pokemon that trainers can obtain by evolving a Squirtle into a Wartortle and then a Blastoise. Blastoise's cannons are very accurate and can strike empty cans from a distance of over 160 feet.
