Lvl 1 trophy Pokemon

lvl 1 : 0
But there are two I keep maxing out that i got before lvl10.
A 100% Jolteon w Thunder (i evolved and powered him without knowing IV lol)
A 93% Venusaur with RL/PB. I use to put him in gyms before the CP update, now it'is more complicated but I invested so much in him that I'm still trying to use him.

I have a level 1, 46 CP Dragonite... it's a beast!

Level 1 Charizard 34 CP
Caught wild during new year event, it has Wing Attack and Fireblast. I used it a couple of times to train gyms, and once to conquer a gym under extreme conditions (under a windy dense snowfall):
There was just a Ditto into the enemy gym, so I left the Ditto trasform into it, and switched attacker into a Golem with Rock Throw...crazy...

Level 1 Snorlax 44 CP

Level 1 Ditto

Level 1 (or 2) Exeggcute 82-91% IV

I think I had a lev. 1 XL Horsea, which I powered up to lev. 3 to precisely calculate IV. It turned out to be 98% :D evolved it into a XL Seadra...

Evolved? None. I do however treasure my 0% IV, 10 CP Magikarp. I always put him on a gym a few blocks away from my home.

Level 1 aerodactyl and kadabra. I use them when training against 100 cp that people drop randomly

I saw a lvl 1 dragonite in a yellow gym once. It was such an odd sight, i can only assume they got it in the wild.

Keeping top attacking move sets for level 1 final form pokemon caught in the wild has been a game-long quirk of mine. What I have so far:

Pinsir: fury cutter, x-scissor
Slowbro: water fun, psychic
Jynx: pound, psyshock
Jynx: frost breath, ice punch
Cloyster: ice shard, blizzard
Tauros: tackle, earthquake
Magneton: thunder shock, flash cannon
Butterfree: bug bite, bug buzz
Beedrill: bug bite, x-scissor
Marowak: mud slap, earthquake
Raticate: bite, hyper beam
and of course Ditto

I think this is lvl 1 if not pretty close...

I have a lvl 1 Nidoking CP31...HP15,
a level 1 Primeape CP27...HP12,
and a level 1 Gyarados CP45...19HP.

level 1 Cloyster IS/B 31 CP 217 possible IV's below 50%. Also have a level 1 Venomoth.

My level 1 Beast

Without checking my collection, off the top of my head...

Snorlax
Beedrill
Chansey (legacy)
Kangashkhan
Pikachu (standard and Xmas)
Arcanine
Lickitung
Fearow
Haunter

For my 'ones and zeros' collection (lvl1 mons or zero IV mons)..I set myself a rule that they must be caught in the wild that way. I won't ever evolve a lvl1 mon to get an evolved version of it (just a little self imposed rule).
I have many more 'unevolved' mons at level1 but they are not worth listing here.

Caught only 1 Dragonite in the wild and it's Level 1. 47 CP!!!

I got Vaporeon L1 WG+HP with low IV...

Caught as a 100% squirt during starter event. Decided to roll the dice and was rewarded with this gym topper!
