OH MY GOD THE FEELS. His mama died so a ditto turned into a charizard to take care of him until he could protect himself ; <--- Or Ditto is actually his dad, and his mom was the Charizard in the relationship
Adventure time and My Neighbor Totoro crossover. BTW My Neighbor Totoro is a really good Japanese movie it's not actually in Japanese it's by the makers of The Secret World Of Ariette and Ponyo. I will admit I am a big nerd for anime!
