sick fanfic but it's actually because bug is the tutorial for Evolution, they're supposed to be weak but evolve quickly to teach the player that evolution is more often than not a direct upgrade, however you have to tone them down so that the player can't just assrape the entire game with a Beedrill
and go figure, the game that first started to miss the point of the bug type and started to strip it of its identity was gen 5, what a surprise
