Wild Charizard

Couple of Blastoise

One Charizard and two or three Venusaur.

Outside of events, a few Blastoise here and there but none of the others. Caught Charizard and Venusaur (also Blastoise) during the starters event in late 2016/early 2017.

None of the Gen1 starters, but I have caught three Dragonites in the wild - one of them was even pretty good.

I came across a small Charizard nest in Tokyo about a year and a half ago. Caught my first one there.

3 Zard
4 To use
4 Saur

I caught one Charizard and three each of Blastoise and Venusaur during the Jan., 2017 New Year's starter event. I also caught a couple of Blastoises during the water event about a year ago, and I caught a random Venusaur a few months ago that was not part of any event.

During this event, I've caught two gen 1 pokemon in the wild for the first time, Dugtrio and Sandslash. After having caught my first wild Dodrio two weeks ago while visiting another biome, there are now only eight gen 1 pokemon that I have not caught wild (I've been keeping track since early in gen 1):

Clefable (encountered one once, but it fled on the first throw)
Primeape
Alakazam
Golem
Electrode
Gyarados
Flareon
Dragonite

I'm hoping to knock a few more off the list before the event ends.

They are pretty rare, more so than wild Dragonite (9 caught without map) in my town.

Outside events maybe 3-4 each of Charizard and Blastoise. 2-3 of Venusaur.

Only one of the 2nd and 3rd gen starter final evolutions is Fergalator (1 or 2).

Charizard, 2X caught once more ran.

Blastoise, once.

Typhlosion, from the research (5X raids). Did Pinap and double candy for 40.

Edit: I've also caught Meganium twice in the wild.

I don't remember when it was but yes...
A couple of Blastoise, Charizard and Venusaur...
Also G2 Starters... Never encountered yet a G3 Starters...

Yes, several. Stumbled on a Blastoise while just in an area (and, at another time, Typhlosion which I couldn't catch since I was still starting out). Then I've used trackers to get Venusaur and a pretty nice Charizard.

I never encounter them in my area!! But I catch 1 machamp every 2-3 days. Machop are common than pidgey, whismer and rattata combined in my area.

A couple Blastoise, a single charizard on a trip. Never encountered a wild venusaur afaik.

Yes, I caught all Gen1 starter final stage from the wild at least once each, but never from Gen2 or Gen3. However, they were always either low level or really crappy IV.

I also happened to have earlier Dragonite than Dragonair. It was a lemon IV, but I was low level and it was by far my best attacker, so I kept boosting it whenever I leveled up. I still use it even in raids and clearing gyms and even used TM's to get DT/O in spite of that... it became sort of a personal thing :)

I've caught all the starters in the wild except Gen3.

No, I'm sure I would remember that because I distinctly remember when I found a wild Venusaur once.
