Ash's Charizard/Manga/Movie adaptations/Pocket Monsters the Movie: I Choose You! Remix

Charizard, as a Charmander, belonged to a Trainer named Cross. Cross released Charmander as he deemed it weak and then Ash eventually caught Charmander. Later, Charmander evolved into a Charmeleon.

In ICYR3, Charmeleon was sent out to take on three at Mount Tensei. Charmeleon's caused the Nidoking to go running. 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.
