Can we have a thread for when established lore and gameplay are at stark contrast?

For example it's repeated over and over again that Dragonair changes the weather, yet absolutely nothing about its movepool suggests this. It doesn't even get Cloud Nine or anything else relating to this.

DragonAIR is also sky blue and cloud white, can change weather, has wings and is constantly said to be able to fly, and seems to truly embody the sky like few other Flying Types do but isn't one, so there's that.

Another is that Copperajah is explicitly stated to resist water, but wasn't given a typing or ability that actually reflects this—in this case I feel it could have been Steel/Grass. It's already green from the copper; now just say it's a jungle-dwelling elephant, which Indian elephants are. It further fits as an herbivore and because elephants are often compared to trees because they are large and have trunks. Copperajah could have also had a thick extendable vine trunk quite like how other Grass Types tend to use Vine Whip, and photosynthesized with its ears mimicking how real elephants use them to cool off from the sunlight.
