>>12606933Bugs are all about manipulation and deceit. That's why they're strong against Psychics; which are incredibly smart, but weak against Fighting, which are too honourable and one-minded (punch-punch-punch) to be affected.
Similarly, bugs, at least in the world, have pretty much no brains to speak of, just instinct. Dark types machinations therefore do not work on them as well, since they're so one-minded that they'll keep doing what they were going to do regardless of any ruses Dark types attempt to pull.
