Pretty much all baby Pokemon are pointless, in my opinion.
I would say Electivire, but if there was no Electivire, there would be no Magmortar either, and Magmortar is one of my favorite Pokemon.
Ambipom, Tangrowth, and Froslass (please don't kill me XD) I find unnecessary. I don't know why, I just don't like them.
As for Pokemon I want to see evolve, there are two: Dunsparce and Medicham.
Dunsparce, because it is one of my favorite Pokemon, but is very underestimated by people when it comes to stats.
Medicham, because I like Meditite's design, but I absolutely just can't stand Medicham's. I kinda wish that Medicham would evolve into something that looks a little more like Meditite.
