heres a hint for links, when answering/ asking a question, if you need to put a link, click the globe with an arrow on it, copy+paste the link into the web address thing, then in the brackets where it says link description here, put something like source, or source1, I should be a link below, then when you are done with the source thing, click out of the brackets.

Answer 2

-arceus via plates, every type
- melloetta via relic song, normal psychic to normal fighting
-darmantian via zen mode, over half pure fire, under half fire psychic
-hoopa via the prison bottle,ghost psychic to dark psychic
-shaymin via the gracieda(or being frozen), grass to grass flying
-rotom via multiple locations throughout the games, electric ghost and electric paired with: grass,water,fire,ice, and flying
-Wormadam via what form it is as a burmy when it evolves, trash bug steel, plant bug grass,sand ground bug
-castform via the current weather, water under rain, ice under hail, fire under sun, and no change under sandstorm, a shadowy aura, fog, strong winds, or normal weather, entering these or switching or being hit by gastro acid also revert it to its normal form.

That's it unless I missed any on the bulbapedia page, hope I helped!
