Best Pokemon Type by Generation, Day 1: BUG

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.

For today's contest, we're doing Bug-types. Very common in early routes, but also offering some very unique designs and combinations later in their respective games. Given Gen VI's limited roster, I have folder Mega Evolutions into their list, as those were, effectively, some of the new Pokemon created in lieu of brand new designs for Gen VI. I'll keep the same concept for later typings as well.)
