My alolan sandshrew (Now an alolan Sandslash!) I wasn't even trying to find it. I was looking for a magikarp.
I caught 3 rare Pokémon in a row one night. Chansey (who has been a thorn in my side for a while), Farfetch'd (best duck), and Aerodactyl (favorite fossil). I am so proud~
Right now it's one of my Alolans. I ran into a few rares (fossils, Electabuzz, Mr. Mime, Eevee) but I either passed them by or couldn't catch them. Oh well, I'm sure I'll find them again someday.
Probably my Porygon, sure Mewtwo was an awesome catch but I looked for Porygon for days while Mewtwo just kinda showed up. That's a scary thought, you with a Mewtwo army.
Finally caught Mewtwo after spending three full weeks specifically hunting for it. I didn't hunt every single day out of those three weeks, but I hunted for most of them. I'm glad I caught it just now, as I had gotten to a point where I was quite demoralised and had lost most urge to even post on LV at all. Yes, I suppose that is a matter of pride, but it is something that I said I would do, and I have made good on that promise finally.
The legendary egg I just caught right now, because, it was pretty hilarious. I only had one pokéball, I used it, it told me it broke out of it anD THEN BOOM NEVERMIND IT WAS CAUGHT. Gotta love this kind of things. xd
Mine was my first legendary egg because I was just trying to read into how some of the forums worked and it appeared.
Mine was my first eevee. I caught it at my very first try and I was proud at myself! It then evolved into Vaporeon and won battles for me, I'm proud at it ^^
Probably Van Hellsting, my Beedrill! I caught him before the catch tables were changed (And so Beedrill can't be found just browsing anymore) so I consider myself pretty lucky! ^^
My Azelf. I caught it on the second regular Pokéball I threw. Then again, it was the second I encountered. The first broke out of all the Pokeballs I threw at it.
