Which "battle areas" reject high-leveled Pokemon in level 50 challenges?

Question

By "battle area", I mean places where players can battle NPCs but not get experience, money, or EVs by winning. Some of them (like Battle Frontiers) have level 50 challenges, where they either reject all Pokemon whose levels are greater than 50 or lower their levels to 50.

Comments

I'm a bit confused by the wording of the last sentence. Are you looking for all locations that have Lv. 50 flat rules, or all locations that reject Pokémon over Lv. 50?

All locations that reject Pokemon over level 50 in at least one of their formats

So you already know the answer to your question.

No, I'm asking for a list of all locations THAT reject Pokemon over level 50 in at least one of their formats. Notice that my previous comment wasn't a complete sentence.

Answer 1

All level 50 flat battles set a Pokemon's level to 50, if the level is below 50 it would either set it to fifty I think or leave the Pokemon at that level.
Now I know that wasn't the question, but y'know, just in case or whatever.
As for rejections of over 50s occurs in generation three or at least emerald by experience and likely also in gen 2 in all battle formats I think, purely by memory.
I am however aware that generation four, gen 5, 6 and 7 all set a Pokemon's level to 50 and don't reject them,if they are lower then 50 then they will stay at the level they are at in battle, because we love our focusend rattatas.
