What pokemon do you always get bad IVs on?

Most of the event-related Pokemon have bad IVs somehow. My biggest chance of getting a high IV one seems to be to catch a Pokemon that's not related to the event.

Also Machop...I am level 38 and have never got better than an 89 IV Machop. In fact, my 89 is now a Level 40 Machamp. Never got a 90 or better. Still holding out hope during this event.

Moltres from 7-day breakthroughs! I have always been unlucky with the starters too, including Bulbasaurs from community day, but it’s partly my fault for always prioritizing high level or weather boost over IV because of lacking stardust.

Magikarp. Used to be common trash in my biome, but never got one better than 93%.

Literally everything from a raid or quest.

Wailmer. My wife caught her first Wailmer as a Raid Boss, and it was a Perfect IV Wailmer. My daughter hatched a perfect IV Wailmer last week. Me? I've got one Wailmer with an 89IV, and 130 others that had less than that.

Most others I have at least 2 with IV's between 91 and 96, though not quite enough yet so that I can automatically transfer some Pokémon without checking.

Rhyhorn, they are all turd burglars.

In the past that would have been Anorith. But now it's Meditite. I have yet to have found one with 80+ IV and 15 attack, never mind seeking shinies lol.

Update: Siny hunted so hard I found 100% Makuhita, although normal one. Good to have in my gym attack team.

I think there are a few, but the two I can think of right now is Mudkip and Torchic.

I've caught 179 Torchic and only one has had good IV.
Mudkip is worse. 427 caught. I have found two with good IVs (91 and 96), but the rest have been awful.

I'm also unlucky when it comes to Larvitar. I think that out of the 62 I've caught/hatched only one had 15 in attack. I'd say that like 90% of the ones from eggs has had 14-15 in HP and really bad attack.
The two Tyranitars with good IVs I have are probably from raids.

Dratini. I've never had one better than 93%. Sitting on 1266 dratini candy, so I've seen a good number.

Beldum. 84% is like my best.

Moltres and Tyranitar. But what goes around comes around.

I have one Mewtwo 96%, 14 att and 7 Groudons , 2 x 98%, 15 att + 1 x 96%, 15 att.

Out of the pokemon that I actually want high IVs: Squirtle family. Almost all wild have been under 80%, and none overall above 90%.

Ralts, Makuhita and Kyogre. I've caught a ton of weatherboosted Ralts and Makuhita and somehow the IVs always manage to be bad.

Definitely Scyther for me, and surprisingly for how common they are, Eevee. I've caught almost 1,000 and have nothing above 93%.

Crappy being relative here since most raid catches are useable and IVs become a matter of splitting hairs, but any legendary I strongly cared about. After 31 Rayquaza raids and only half of those being successful catches I don't think any of them broke 91% - A majority of them I doubt broke 80%. Moltres was another problem child until I bagged a 96% from research; none of the six I actually caught last summer cleared 80%. Six Mewtwo catches later and the only one I caught that breaks into the upper 80's has a whopping 10 atk IV.

Scyther

Groudon. Caught 10 of 13, 1 at 89%, 1 87%, and the rest much worse than that.
Machamp raids, I would either get good IVs with steel moves, or crap IVs with C/DP, back when I didn't have enough CTMs (or FTMs, for that matter).
