Gens 7 & 8 have been jarring, but I'm realizing the tonal and thematic whiplash of ORAS was a unique blend that hasn't been replicated since.
>meeting Regigigas requires a NICKNAMED Regice holding a CASTELIACONE, which makes Truck Mew sound absolutely normal in comparison
>Sea Mauville documents detail the failing marriage of the Cozmo family for some goddamn reason because he of all people isn't allowed to have nice things
>the airspace is littered with spacetime rifts and whatever the fuck Hoopa was doing (never explained)
>the postgame antagonist is a fucking chimpanzee who punches out Poké-NASA to save the people of another dimension who may or may not even exist; this person is presented as a good guy even though her actions nearly killed every living thing in the region TWICE
>Wattson has a trophy wife who doesn't even seem to be of drinking age
>the guy who hands out Lopunnite is terminating another guy's tenancy; it's played dead serious, and the player can do nothing to help
>Team Aqua is blackwashed, but that's small potatoes compared to everything else going on
>Looker drops out of the sky with amnesia for some fucking reason (also never explained or resolved)
>the new Wallace is a stripper who has groomed his niece for child pageantry
>the genesis of Mr. Bonding happens on-screen via the fusion dance of six old men

There's probably plenty of shit I'm forgetting, but the stuff I do remember was an absolute fever dream. The only recent thing that compares is the Haina Desert spaceman in SM, who himself seems to have been an offshoot of the Mr. Bonding insanity. This isn't a commendation or indictment of ORAS in anyway. This is just a lookback on the sheer "what the fuck" factor.
