gen 1 clears pretty comfortably here, a lot of gen 1's entire flavour just came from these lines.
gen 2 is pretty underrated honestly, I really like Spinarak and Ariados and Crobat is a poison type of all time for sure.
gen 3 is an odd one, Swalot is a bit underappreciated and Seviper is a narrow improvement over Arbok overall imo, but Dustox isn't even the best moth pokemon up to that point and Roselia is nice but again not my favourite of its line, even if it's also the only one in it that could've possibly stood on its own as a standalone mon.
gen 4 falls apart outside of Budew/Roserade/Toxicroak line.
gen 5 has scolipede line which i hate with a passion, and amoongus line which i also just dislike immensely. relying on garbage to save this gen is a lost cause
gen 6's poison mega lineup is good, though it also reminds me that i really wish most people didn't just show strong favouritism towards mega gengar specifically. dragalge line sure does exist
gen 7's alolan variant reps here are honestly some of the only ones where i don't consider them strictly like, overall worse then the originals. but still all i think of when seeing them is just "why though". side note, funny that it's the rainbow coloured one with the dark type. also i guess i like nihilego but everything else is whatever
gen 8 also did good with
half
of its reduxes, Galarian Weezing was over the top but welcome, and Overqwil was also a welcome addition too. Really wish new Slowbro/Slowking and especially Sneasler had never happened though. Also Toxel is an f-tier baby pokemon
gen 9 was a return to form if only for the dlc mons. Pecharunt is fun in all its hax bs glory
