Which Pokemon had their ability switched ?

Lots of Pokemon have switched their abilities over the past gens but as I am too lazy to search for them all can you guys tell me. Oh and maybe why they were switched (just curious)

Note: I don’t mean abilities that change your ability I mean the Pokemon that had diferent abilities before gamefreak changed them
