What was the rarest Pokemon that you encountered. Did you catch it? What was the CP/IV’s? For me it was a 247 Dragonite which ran away. My friend caught the same Dragonite with around 2500 CP second try.
Probably Dragonite, the latest one having 2434 CP and pretty weak IVs. I’ve encountered and caught two Dragonites in the wild so personally it hasn’t been the most uncommon Pokemon for me. I just caught my first Doduo today. I’ve got quite a list of Pokemon I’ve only encountered once, of which I would mostly like to meet another Scyther. Another Lapras or another Snorlax would also be nice
