While butterfrees are admittedly cute and overall stronger than beedrills, I still like the bees better, if only because they're yellow and strangely lovely when they go around buzzing in packs. I've always found hives fascinating, and the way fully grown beedrills protect kakuna cocoons is just so endearing <3
Beedrills are common pokemon and definitely not one of the toughest species around, but they have their own special charm. (…At least to me.)
