Top 3 catches?

snorlax
gyarados
exxecutor
dragonair

1. 3x Dragonite
2. 3x Snorlax
3. 2x Lapras

My best catch was a 1406CP Snorlax that was on my block. Was my first wild Snorlax I caught and it just happened to have ZH/Body Slam.

It is now sitting at 2930CP and am still walking for more candies. Put a lot of dust and miles on to get him over 2900CP.

2nd - Shiney Karp. Only 34% but is now a 2833CP Shiney Gyarados.

3rd - 87% 15attack Egg now a 2722CP C/Solar beam Exeggutor.

1. 1x Dragonair 22CP
2. 1x Snorlax L/HB
3. 150x Heracross (they spawn like pidgey's and I still get excited when one pops up :))

1. Dragonite (1300 Cp)
2. Aerodactyl (1200 Cp)
3. 8x Snorlax (from 1700 to 1800 Cp)

HM. Vaporeon (2200 Cp)

Everyone have terrible IV, except for Vap

1. Level 30, 100% IV Magikarp. Gyarados has Dragon Tail and Crunch
2. Level 30, 96% IV, CP2878 Snorlax with Lick and Hyper Beam
3. 98% Vaporeon with Hydro Pump. Caught it at the beach back in August.

Honorable Mention: 1st wild Lapras on the Navy Pier in Chicago, was an adventure catching it.

Those are the most memorable ones

2 x snorlax (same day)
5 x labras
2 x gyarodos
2 x exxebutor
lvl 30 89 iv jynx

Although I have lived in two really small towns, maybe because it is near university, I did occasionally get good spawns.
4 all over 2200cp Snorlax and all with zh/bs but with low IV
Three around 500cp Lapras but with second tier IV

Aerodactyl, 2 Granbulls (same moveset lol), 2300+ Arcanine, a couple low-iv Snorlax I transferred to feed my hatched ZH/BS. An Ampharos ran away but by now I evolved a better one.

1. Dragonite (x2) - First one I caught a week into the game at 1000 CP with 78% IV. Now is 3285 with Steel Wing/Dragon Claw.
2. Snorlax (x4) - First one I caught a day after the above at 500 CP and 95% IV. Now is 3092 with Zen Headbutt/Hyper Beam.
3. Lapras (x3) - First one I caught around a month into the game. Had Frost Breath/Ice Beam, but only 900 CP with about 20% IV. Hatched a 98% IV one with Ice Shard/Ice Beam (my main Lappy since) a while later.

HM. Feraligatr (x1) - Caught about a month ago with Water Gun/Hydro Pump, 2026 CP and decent IVs. My main Feraligatr since the one I evolved got Bite/Crunch.

2800+ Snorlax with ZH / HB 82IV
1 Dragonite
1 Lapras.
Level 28 Typhlosin the first night of Gen 2 in an incense.
My first Venusaur and Blastoise were both pretty memorable too (pre-event and didn't have to candies to evolve them at the time).

Before nerf it was 98% IS/IB Lapras, now I don't know, maybe 2700ish dragon with lousy iv and SW/HB, I'll never power him up, so it make him almost useless, all laxes have lousy iv.
Maybe 91% larvitar or 98% karp. My catches aren't outstanding.

1. Eevee 100%, my Rainer, has probably earned 2000+ coins by now
2. Porygon 4%, before Valentines, was last required catch for my Gen I available-dex
3. Snorlax 40-49% (Lvl 25, L/BS), I suppose, even though I hardly ever use it

1. Dragonite with legacy DB/DC, excellent fighter despite 38% IV
   I forget what CP she had, but caught her after only 3 weeks so it was pretty low.... Currently maxed out at lvl 34.5/3036
2. Snorlaxes: CP 1940 with legacy L/BS;
   CP 2156 with ZH/HB
3. Vaporeons: CP 1883, 2072

1. Dragonite Db Dc ??? (2691) 78%
2. Snorlax L Bs 2493 61%
3. Snorlax Zh Bs 2584

1. Feraligatr 91 IV
2. 3x aerodactyl
3. Togetic

Funny because this was all in Australia and I live in The Netherlands
