>Rowlett
Higher HP than Litten and Popplio. Decidueye doesn't gain HP upon evolving. Primarina ends up being the one with the most HP.
>Incineroar
Loses 30 speed points upon evolving
>Lycanroc Midnight
Gains defense rather than speed upon evolving, which makes its "signature" move (Counter) less effective since it receives less damage from moves that don't OHKO it (because even then it is pretty frail). Also Counter has negative priority so it being slow doesn't help with it at all.
>Crabominable
Loses Speed upon evolving and its defenses aren't that great, making it a slow, frail ice type which is a death sentence to any pokemon.
>Lurantis
Slow pure grass type with subpar bulk. Its signature is a physical solar beam yet it'll hardly ever survive two turns since it has tons of weaknesses
>Morelul
Base 50 HP and base 130 defenses makes Innnars Out really hard to use since lots of things can't OHKO it, meaning they won't get much damage when it faints.
>Palossand
Base 75 Sp.Def makes Water Compaction nearly useless since most water types are special attackers
>Zygarde 100%
Only stat that changes is HP, which is not really a good thing sine Power Construct activates when 50% Zygarde's HP goes below half.
What's up with all these weird stat changes upon evolving and awkward stats distributions that go against the pokemon's intended gimmick?
