Sometime before [[ICYR3]], Charizard, as a Charmander, belonged to a Trainer named Cross. Cross released Charmander as he deemed it weak . Ash then took it in. Later, Charmander evolved into a Charmeleon.
Charizard made its actual first appearance in [[ICYR3]] as a Charmeleon . It was sent out to take on the wild Pokémon at Mount Tensei. Later, it was used to battle Cross's Incineroar. During the battle, Cross's Incineroar got the upper hand but Charmeleon evolved into Charizard when it was about to lose. Using its newfound power, Charizard defeated Incineroar with Seismic Toss. Charizard then faced off against Cross's Lycanroc but the outcome was unknown.
