>>54728779I’m glad GameFreak are having a mini-Poison renaissance right now. There’s a lot of Poison Pokémon lines but for the longest time it just felt like they relied on the fact they introduced most in Gen 1. But even now a lot of it is revisiting Gen 1 and 2 Pokémon.
Gen 1 - 13 lines (All new type combos since it’s the first Gen)
>Venusaur line >Beedrill line >Arbok line >Nidoking line >Nidoqueen line >Golbat line >Vileplume line >Victreebel line >Venomoth line >Tentacruel line >Muk line >Gengar line >Weezing line Gen 2 - 1 new line, 1 cross-gen, 1 solo, no new type combos
>Ariados line >Crobat (Cross-Gen/new line end) >Qwilfish Gen 3 - 1 new line, 1 final evo, 2 solos (No new type combos)
>Dustox>Roselia >Swalot line >Seviper Gen 4 - 3 new lines, 1 cross-gen solo expansion (prevo and evo), 2 new type combos
>Budew and Roserade >Skuntank line >Drapion line >Toxicroak line Gen 5 - 3 new lines (No new type comboes)
>Scolipede line >Garbodor line >Amoongus line Gen 6 - 1 new line, 3 Megas, 1 new type combo
>Dragalge line >Mega Venusaur >Mega Beedrill>Mega Gengar
