Here's a sneak preview regarding a particular thing that has bugged me....
Many fans complain about what size they are depicted, especially in the anime.
Pokémon sizes are NONSENSE - Pokémon Fact of The Day
by TheJWittz (2013)
This has led to accusations that the animators haven't done their research properly or taking artistic liberties. However, I don't. That is because (unlike most people) I don't see the statistics given in the Pokédex as absolute fact and that every member of one species only comes in just one size and weight. In the real world species don't do that (unless their cloned). They come in varying degrees in size and weight. For example, the average height of an American adult white male is 177cm or about 5ft 10in (which is my actual height). But we all know that not every white adult American male is 5ft 10 in tall. Some are taller, some are shorter. With this in mind you shouldn't be surprised that when Ash's Charizard entered Charicific Valley in this episode he was a small runt compared to the others. This could have been an easy visual cue used to show his youth compared to the older (larger) charizards in the valley. But the fact remains. It's impossible for all normal Charizards to be 1.7m high and weighing 90.5kg. Some are smaller due to lack of nutrients during their youth. Some are big because of excess of nutrients throughout life, which (I imagine) Charicific Valley isn't lacking of. So stop complaining and stop accusing the animators for sloppy work. Do you know how hard it is to work on an animated TV show? I studied animation (and made a few myself) and that enough gives me an idea of how much time and effort goes into making animated shows and films. So shut up!
