Best Pokemon Generation by Type, DAY 11: Gen 1 Water vs. Gen 8 Poison

I've done this style of poll contest once before, back in either Gen VII or Gen VIII, so why not try it again now? The rules are simple: each day, I'm going to post a poll for a given Pokemon typing, with each generation's roster of new Pokemon filling in that typing. You just need to look at what each generation had to offer, and select which generation you think brought the best new roster (for any reason; you could say that a single Pokemon was so good that it overwhelms everything else the generation spawned, or you could select a generation that may be more well-rounded that the one that created your personal favorite). At the end of the day, one generation will be crowned a champion (with potential tiebreakers if need be), and that generation will advance to a second round, where the eighteen winners, and fourteen strongest runner-ups will be sorted into a 32-entrant tournament to crown which generation produced the best overall roster of a single typing.

The tournament has now begun. The discussion topic is here: https://gamefaqs.gamespot.com/boards/8-gamefaqs-contests/80744044 and the bracket is here: https://www.bracketmaker.com/tlist.cfm?tid=478370

Today's match features Gen I Water, which is so abundant that I couldn't even fit the word "line" alongside most of the Pokemon listed. It will be facing off against the first of two Gen VIII wild cards to make the field, this time with Gen VIII Poison. Poison didn't have a strong showing in its first appearance in the tournament, so we'll have to see if the underdog can dethrone Gen I for the second day in a row.
