>>27758111I think around half of all existing Poison-types came from Generation I, if not more.
Gen V had a golden age for Bug-types with plenty of great additions. Gen I kind of already had the Poison golden age from sheer quantity, but a lot of them have been left behind. I'd appreciate a Poison renaissance, reinvigorating old members and introducing new/uncommon combinations, but it seems unlikely.
At least Alola is giving us the fabled Fire/Poison.
>>27758175We got Dragalge. A poisonous sea dragon is way better than a walking booger.
Adaptability boosts its meh Sp.Atk, and it has solid Sp.Def for dealing with moves like Moonblast. I like using it in doubles.
