Charizard is the final evolution of Charmander in the Pokemon series. Since appearing on the cover of Pokemon Red version, he's been pretty popular with fans ever since. I like him because my Blastoise could easily take him down.
I also remember Charizard in the Pokemon anime. He was super strong in it.
Except he never obeyed any commands by Ash until much later on. Bummer.
I recently had to fight him in Pokemon: Heartgold, and Red's Charizard had some power. Even my strongest water pokemon had to struggle to finish him off.
And of course his original Pokemon card. This one piece of cardboard was worth about $150 back in the day easy. If you had one, you were admired by all those who played it. Consider yourself lucky if you managed to get one.
I didn't like him too much in Super Smash Bros. Brawl. I mainly stuck with Squirtle.
His Japanese name is リザードン (Rizadon) which is based off the English word "lizard".
