Egg Pokemon Chart

The buddy --- egg distance system is broken since they removed eevee from 10 km eggs, she still a 5 km buddy. It also happens to all pokemon removed from 10 and 5 km recently, like slowpoke (2km egg, 3km buddy) and magby ( 5 km egg, 5 km buddy)

I don't know where people got this idea that all pokemon from a given egg hatching distance have the same buddy walking distance. It's just plain not true. For example, Bulbasaur and Charmander have always come from 2k eggs, yet they have always been 3k buddies, unlike Pikachu, who has always been a 1k buddy.

At the initial introduction of the buddy system, there were other similar examples of certain pokemon that didn't have the same buddy distance as most of the other pokemon with the same egg distance. The buddy and egg lists were similar, but not identical.
