>>37220489Some more info I just thought to add. A lot of people here seem to think it was supposed to be an actual t-rex come to life, but Shudo's own explanation makes it clear it's supposed to be a moving fossil. He describes it coming to life as a blue light starting to glow in its eye socket, and he continues to refer to it as a t-rex fossil in the rest of the summary.
And to give further detail on the theme of the movie idea, it was supposed to be make you question the world you live. Shudo goes into this when talking about this movie idea, and he goes into it a bunch when discussing Pokemon episodes he wrote, like the Diglett episode. Basically he was really obsessed with the idea that humans are unable to understand animals, and any attempt to do so requires anthropomorphizing them past what can objectively be known. Shudo goes into how it required to anthropomorphize the Pokemon in order to write drama surrounding them, but in doing so the Pokemon are effectively the same as humans with different shapes and powers.
Presenting the fact that there's a t-rex fossil in the Pokemon world, a world that had been established as being made of just humans and Pokemon (or just humans, as Shudo metaphorically saw it) would make one question the concept of what the Pokemon world is. The t-rex fossil is meant to be a force not able to fully understood by the characters, the same way animals and other outside forces aren't fully understandable by humans, confronting you with the question of how to define the world you life in, and what it means to exist in it, among other creatures and forces that are outside the bounds of human motivation.
Basically, trying to argue about whether a Pokemon could beat a t-rex or whether it makes sense for animals to exist in the world is missing the point, because Shudo didn't give two shits about the Pokemon universe as a universe. He just wanted to use Pokemon as a vehicle to tackle existential questions.
