I really didn't expect Eevee to be in the Q&A section or a huge variety of Pokémon in the Game Corner. Remember when everyone was in my Q&A because an Eevee was found there?? Pepperidge Farm remembers.
I believe I was the first to find a Shiny? I also remember finding some Aerodactly in the Game Corner... two of them at least. Also Lapras. but no pokeballs
So I've found 4 Mewtwos and have caught 3 of them so far. Did not think that would ever happen that's for sure....
I'm just going to give you the evil eye forever. More on topic, I suppose, I was surprised to not find Machop or Abra in the Video Games section at all, but I found literally every other commonly known species. This leads me to believe that they are both indeed section-exclusive (Machop I already knew that about, Abra I didn't). Seems there aren't quite as many section-exclusives as was previously thought.
I found a MissingNo. That was pretty weird; I hadn't been expecting it at all. Is that a new Pokémon, or is it a new addition?
https://lakevalor.net/threads/rare-pokemon-riddle.18742/ This thread explains the answer to your question succinctly well, I believe.
So I found two shinies in one day (Staryu and Cubone)..... Before that I didn't even know if they were even possible to find like everyone else. Quite the insane surprise!
I found a wild Beedrill today. Very pleasant surprise because Beedrill is my favorite Bug-type Pokémon. And ofc, I have to give him an awesome nickname. So I went with van Hellsting.
I find so many eevees here and there in different forums like GameCorner, QnA and SafariZone. I throw a great ball every time eevee appears, but it always breaks free. I'll throw an ultra ball next time.
Oh right, this topic exists. I forgot about that. ...I was trying to hunt to catch all of the Unown in the Q&A forum (I still am; there's only 1 left), and in the process of my hunt I found and caught a shiny Magnemite. ...Definitely didn't expect that.
I was hunting for Unown in the Q&A section about a week ago I think, and I found two Mewtwos while trying to track down all the letters.
But is not my fault I found two of them. XD It still doesn't make up for the two I skipped by accident ages ago.
I know it isn't your fault; it does still subtly bother me that people found multiple Mewtwos while I spent almost a whole month looking for just one. I know that also is hardly fair on my part; I've had some strange claims to fame as well (like two Missingno. found within an hour of each other), but the Mewtwo hunt is something that subtly bothers me, even though I know it definitely should not.
I ended up in the USUM section after clicking on a bunch of thread links and I didn't even realize it till I came across a Alolan Meowth!
Seems like it's been mentioned before, but I was surprised to stumble upon an Eevee in the Q&A. I guess I'm so used to looking for them in the Intro Lobby that it was a shock to find one anywhere else.
I was shocked to find a Suicune perusing through The Lounge, back when I first caught it. I was searching for Azelf and I didn't even think the gerbils had been released yet. Lo and behold, there it was.
