Unique mons

Unown
Kingdra....waiting on my first Dragon Scale

I need to evolve a Meganium, but thanks to this event I can do it twice already.

Houndoom
Marcargo
Bellossom
Kingdra
Espeon
Umbreon
Charizard
Blastoise
Meganium
Omastar
Kabuto
Porygon
Chansey
And many more.
Also some never caught, like those Laprases, I didn't get at least one during the water event.

Still need Ampharos, Tyranitar (have candies but waiting for a higher than 90%+IV one), Sneasel, Piloswine and Unown.

As you can see ice mon are a pain for me, it is crazy their spawn rate on my area, I have been playing every day since launch, just reached level 37, and only have around 40/50 ice mon in total... I am crossing my fingers for an ice event soon...

Don't have any regionals either a part from MrMime that is my exclusive.

Five of those are on my zero list, and my "Just One" list is quite a bit longer than yours. I'm level 33 also, and my pokedex is at 211 caught.

Singles:
Charizard, Venusaur, Blastoise, Sandslash, Nidoqueen, Nidoking, Ninetails, Primeape, Poliwrath, Machoke, Graveler, Golem, Magneton, Grimer, Cloyster, Gengar, Hypno, Electrode, Marowak, Rhydon, Chansey, Gyarados, Porygon, Omastar, Kabutops, Dragonair, Meganium, Feraligatr, Crobat, Pichu, Cleffa, Bellossom, Politoed, Wobbuffet, Girafarig, Forretress, Scizor, Sneasel, Magcargo, Piloswine, Kingdra, Hitmontop, and Smoochum.

Most of those 100-candy evolutions, I either could evolve more of them if I wanted (such as I have 207 Bulbasaur candy), or I could have evolved more if I hadn't decided to evolve a bunch of the mid-stage forms instead (such as 22 Nidorina).

And my Gen 1 Zero list:
Dugtrio, Machamp, Farfetch'd, Muk, Hitmonlee, Kangaskhan, #122, Jynx, Lapras, #144, #145, #146, Dragonite, #150, #151.

So I'm mostly down to the regionals and things that aren't in the game yet for things I've never gotten yet.

Gen 2 Zero list:
Typhlosion, 176, 180, 181, 192, 201, Granbull, 213, 214, 222, 225, Houndoom, Porygon2, 235, Miltank, Blissey, 243, 244, 245, 246, 247, Tyranitar, 249, 250, 251.

So for gen 1 l do not have enough candy for second Machamp, Dragonite, Snorlax, and Charizard.
Gen 2 it is typholson, ampharos, tyranitar, steelix(only found one metal coat), girefarig, Blissey, stantler, militank, and unown

None of Gen 1 (have at least 2 of each)

Quilava
Croconaw
Feraligatr
Scizor (because I made 3 Steelix instead of a 2. Scizor)
Politoed
Sunflora
Bellossom
Espeon
Umbreon
Shuckle
Magcargo
Pupitar
Tyranitar

I have 0 of

Meganium
Typhlosion
Ampharos
Unown
Hitmontop

and all regionals except Mr. Mime

Houndour is very annoying in its uniqueness for me, I went to a supposed nest on the other side of the city and still got only one :( Other than that, I have a Chansey I don't care about, an Ampharos I don't have any candy for, a Muk I'll probably walk 'cos it's easier that all these 5km buddies, one Scizor with double steel moves who will have mates only if I get a spare Metal Coat, one Porygon2 and not so many candies for another, but a handful of annoying Up-Grades. Tangela with Infestation I don't care about, Hitmontop, Croconaw.

Playing since august lvl 33 still no dragonite... Yaaaayyy

1} Espeon
2} Umbreon
(used name tricks, no time to walk Eevee buddies, it's economically convenient to walk Blissey)
3} Girafarig
(Never met one by chance.
Fortunately I was told there was a nest, and went there to had a Giraffa to my Dex)

Same on u i m lv 33
