Do you keep god-tier Pokemon?

A 0-0-0 level 21 Exeggcute appeared in my house last night. Better believe I kept it. It's the only one that I ever caught (that I know about). I also have two 10-10-10 Suicine that I kept.

Yup I keep all 0% IV, I check all the trash ones just to make sure I don't throw one out. Have about 8 of them it's a nice little mini collectors item.

I caught a 1995 Rayquaza today, came with no TMs, no rare candy, 13 golden razz, 3 revives, unnoticed number of potions. At least it was against AS/AA since only had 3 fighting it, otherwise a complete pit. In the past week I've hatched 98% Trapinch, 98% Swablu, 98% Mareep...all 15 attack. Pretty sure I've thrown a lot of good stuff away since start of the game...positive I've thrown a lot of REALLY bad stuff away.

I keep 0% if I notice them.

No.

I'm keeping them too, especially that despised diglett and some legendaries

000 is a keeper. Legendary 101010 is too. Hatched 101010: NEXT!

Lol i have a 10/10/10 mewtwo

It's unlikely I would even know if I got one. If a common mon is low or mid-level, and I'm busy grinding for stardust, I'll transfer it without checking IV's. And if I do check, and it's in the lowest appraisal range, I usually won't take the time to check the specific IV's before transferring.

I keep them and have several, with probably Eevee being the most valuable. It's not arguable but simple fact that they are rarer than 100% mons.

Yes, but I found them even more common in practice. I have encountered 4, but only 1 100% and it ran away lol.

I had a 10/10/10 Machamp from a raid for a long time but was recently purging my inventory and it got the axe. At the same time I also got rid of my 0/0/0 Minun, which was thematically fun but not enough for me to justify holding on to it.
