People that use 2 different versions of the same species of Pokemon between battles

Just something I thought might be interesting to talk about. Most characters you can face multiple times will usually keep the same Pokemon for future battles but sometimes if you look closely enough, you’ll notice something about the Pokemon that points to it being a different member of the same species rather than the one you previously fought.

Here’s 2 examples, Mable from XY uses a different Houndoom (even if she could change its ability at this point, I don’t think there’s any way you can level a Pokemon down by 2 levels) and Cynthia uses a Lucario with a different nature for her post stark mountain battle in BDSP.

Any other examples you all can think of?
